Suffolk Roadsafe to bring road safety campaign to many more travellers

After complaints about significantly increased levels of aggression on the roads, I’ve heard about some radical new plans by Suffolk’s Roadsafe team to make sure that their education programme gets to every road user in Suffolk. The poster campaigns, tv adverts, the website, and road shows are only allowing them to talk to a very small proportion of people who drive, cycle, or walk in Suffolk.

From today, 1st April 2015 the Suffolk Roadsafe team will be out running roadblocks on every entry point to the county, with some other roadblocks at strategic locations. Minor roads on the county boundary will be closed to motor traffic. At the roadblocks drivers will be asked random questions from the driving theory test. If the driver passes then be allowed on their way.

If drivers struggle with the questions the driver will be held to get some additional training. This is likely to affect people who have forgotten the rules of the road since passing their driving test, or passed it a long time ago and not kept up with the new rules since.

They are also planning to provide a variety of pedal cycles so that drivers can experience what it feels like to be someone on a bicycle. Random drivers will be selected for this to encourage more mutual respect between modes, through experiencing what it’s like using the other modes of transport.

Train passengers are not forgotten about either as the Roadsafe team will be working with Abellio Greater Anglia to broadcast information over the tannoy, and road safety information leaflets being given to passengers.

There will be long delays on the roads, however they are hoping this scheme will make the roads a friendlier place for all road users. If drivers continue drive without courtesy to others the Roadsafe team are looking to work with Westminster to pass some new laws, which mean that anyone who can’t pass a driving test at a random point in the future will have their driving license revoked.

Happy April Fools Day.

Deichmann in Bad Schwalbach

Das Personal bei Deichmann in Bad Schwalbach ist freundlich und hilfsbereit. Als Rollstuhlfahrer kann man dort sehr gut zwischen denn einzeln Gängen gut hin und her fahren und das man an die Regale kommt.

Auch der Behindertenparkplatz ist schön groß so das man keine Probleme beim ein und aussteigen hat. Auch von der Länge ist der Parkplatz sehr gut das ein großes Auto mit fast 5,00m Länge ganz rein passt.

Wenn man dort parkt hat man die Möglichkeit nicht nur bei Deichmann einzukaufen man kann auch noch bei Takko und denn Pennymarkt gehen auch der Edekamarkt befindet sich auf dem selben Gelände so das man als Rollstuhlfahrer nicht jedes mal denn Rollstuhl verladen muss um in ein anderes Geschäft zu kommen.

Presentation of highway links

Example: Heston and Finchley

The slip roads are highway links (motorway_link and trunk_link respectively). The problem is that in Mapnik they flow over trunk and primary (proper) respectively instead of under, causing them to "bleed" over (sic). This causes presentation issues, especially when zoomed out.

Most maps in the world tuck slip roads under the main carriageway, and Mapnik used to do that.

Bat Bridges, or why deleting lonely tags is a bad idea

The other day I was idly browsing the blog of Mark Avery, the former conservation director of the British bird protection society, the RSPB. One item caught my attention: it was about 'bat bridges'. Although I hadn't heard of them before it was pretty obvious what they might be.

A bat bridge on the A590 in Cumbria

Bats tend to follow linear features in the landscape when foraging at night, at least in part because they provide protection from predators. Bats tend to avoid flying over open spaces. Hedgerows, edges of woods, and so on, form commuting routes between roosting and feeding sites for bats. When these are damaged or destroyed, for instance by road building, bats either lose feeding locations or have to cross the open space. Usually they do this by flying low: effective against their age-old predators, but not much help when confronted by a car.

Bat bridges are an attempt to mitigate against the loss of the landscape features used by bats. Often, mitigation is a requirement for the planning permission for a given project. Notoriously, there is often not a requirement to see if the implemented mitigation measure is effective. A group at Leeds University have studied several bat bridges in the UK, and have come to the conclusion that they are more or less useless.

I don't remember seeing a bat bridge and I wondered where they had been installed. Wikipedia has quite a comprehensive list, but without detailed location information. A quick check on taginfo showed precisely two instances mapped on OSM, simply as "description=bat bridge", which turned out to be on the A38 bypassing Dobwalls in Cornwall. Not surprisingly the user who mapped them was at a loss for a suitable tag, and had added man_made=wildlife_crossing and bridge=yes together with the description. Not totally accurate, but entirely useful for finding these structures.

Mapping & Tagging Bat Bridges

As the Derbyshire Bat Group noticed my tweet, I decided that it would be interesting to make the tagging more regular and to add more examples based on the wikipedia listing, and wikimedia and geograph photographs. It was extremely helpful that there were two existing examples because this gave me a good idea of what to look for on aerial imagery: essentially something like power line wires but with obvious (because all are new installations) concrete footings on either side of the road. I had to search up and down the lengths of roadway more than once before I located the bridges, but in a relatively short time had added 9 more to the two originally mapped.

In deciding how to tag them I checked the documentation for wildlife crossings and it seemed appropriate to use adjectival or sub-tagging to separate bat bridges from other types of wildlife crossings. Thus the tag wildlife_crossing=bat_bridge was born.

Various people maintain that tags with a small number of values are useless. Whilst this is true in cases of mis-typing, it more usually reflects something else: a specialised interest, lack of observations, lack of a suitable tag, or simply a lack of time to map such detail. In this case being able to show where bat bridges are located is of immediate interest, and part of the data which conservationists might need when discussing transport policy, as at a conference hosted by Bat Conservation on Tuesday. Curious structures across main roads might also pique the interest of people passing, and general inquisitiveness is certainly a common trait in OpenStreetMappers.

I hope describing the background to a rarely used tag shows that such things are often meaningful and useful, even if the usage might be niche.

Low occurrence tags in general

There are two general aspects of using such a tag which are of more widespread relevance to OpenStreetMap as a whole:
  1. The danger of removing meaningful tags inadvertently
  2. Specific keys versus a more generic key and sub-tagging. 
I'll only talk about the former in any depth in this post. The second subject is very broad and involves interesting issues about how to choose an appropriate abstraction level for database design in general.

Before getting into the nitty-gritty of this post, I thought I'd lighten the tone by listing some of my favourite rarely used tags:

Stile with dog gate OS SY567846
Stile with dog 'guillotine', more formally a dog gate.
Source: Wikimedia Commons.
  • Dog Guillotine (dog_guillotine=yes; 52 uses). Not a device for murdering dogs, but a simple vertically operated gate to allow dogs to pass through a fence, usually alongside a stile which many dogs find difficult. This tag is very memorable, much more so than its more formal, but also more prosaic, moniker of 'dog gate'
  • Research Institute (amenity=research_institution; 54 uses). Perhaps I'm attached to this one because I worked in a few , as did my father and many friends.
  • Soft Play Centres (leisure=soft_play; 11 uses). Indoor areas where small children can play protected by soft matting. Usually commercial. There was deep scepticism about these when the tag was first raised, and all are located in the UK. However, I did see one in Ushuaia, so they're not necessarily a British thing (see also this). Probably an excellent example of a tag where mappers arent noticing/cant think how to tag. (Incidentally, in writing this I find that another tag (indoor_play) has been introduced for the same thing since I last used it. This is a common phenomenon for low-occurrence tags because they inevitably have a low profile. This is also a good example of a more generic versus more specific tag. Re-tagging soft play areas to indoor play loses some precision of meaning).
  • Sitting Disability (sitting_disability=yes; 48 uses). Used to indicate that swings (and other equipment) in a playground is appropriate for children with postural disabilities. Part of a well thought out, and moving, tagging proposal. I have yet to map playgrounds in sufficient detail to add playground equipment, but this is the type of thing which makes doing so worthwhile.
  • Pet Crematorium (amenity=crematorium,crematorium=pet; 2 uses). I came across one of these the other day whilst out surveying, but there's even a professional association. (A good example of where choice of generic vs specific key is hard, see below).
These are either things which interest me, or which I've come across. I'm sure every mapper has their own list. This is one reason why low-occurrence tags exist.

    Why cleaning up low-occurrence tags requires care.

    There is a tendency to treat all rarely used tags as rubbish. It is therefore important to understand how and why they might be created.

    A recent example, was the removal of some tags which we use locally in Nottingham. We use an extended version of the not:name tag to highlight discrepancies between Open Data from the city council and OSM: partly to help mappers who might be tempted to use the open data without checking how up-to-date it is, and partly to provide the ability to feedback to the providers. (At the recent OpenDataCamp I was delighted to learn from Dr Sian Thomas of the Food Standards Agency  that a small bit of feedback I provided to a local authority, had been very effective. I am now more determined to help where I can in improving data quality for Open Data providers, and this is one mechanism towards such a goal).

    The mapper who removed the tags was unaware of this usage and could see no value in the tags. In this case the new changeset comment feature enabled us to chat with the mapper who had removed the tags and resolve the issue. Given the structure of the key (not:<data provider>:<data set>:<osm key>) these do not lend themselves to a wiki page, as there are around 40 data sets we use, and perhaps 5-6 OSM key values as well.

    Of course there are many keys with a small number of values which can be altered to make the data more valuable, but it is rare that they are directly amenable to an automated edit. The most usual ones which can be caught are typos for widely used values, which can be identified when the value corresponds to a typical value of the intended key (e.g., hihghway=secondary).

    Here's a sample list of single values for shop in Australia:
    "gps", "garden_equipment", "real estate", "Pet Supplies", "building_supplies", "art_supplies", "random_crap", "hunting", "loan","Coles Express", "hydroponics","kayak; canoe","solicitor", "electronics;hifi","TV repair", "wines/art craft", "Linen", "tax_agent", "baby_goods", "video_rental", "beads", "watches", "alterations", "skater", "optometry", "photography", "fresh_produce", "antique_shop", "sewing_machines", "air_conditioning","farm_supplies", "farm_machinery","office","Onsite Rentals","nails","Homes","carwash", "property", "home_brew". 
    Every one of these is intelligible, some, such as antique_shop can be mapped to a more widely used value (shop=antiques). random_crap is just pure genius, we all come across shops of this type, but are rarely brave enough to say so. Changing many of these values may remove information, for instance optometrists do different things to opticians, although many may well be opticians as well. Furthermore the locations may have been mapped some time ago and things may have changed.

    Places in Europe with gas lighting via Overpass
    An example of a tag which is rarely used due to historical change.

    All keys and tag values started out with a low count, some prove to be universally applicable, others might be specific to small areas (see lit_by_gaslight), and others still are of minority interest. Low counts are not a bug in themselves. Indeed, it is often possible to rapidly increase the number of mapped objects once a sensible tag appears.

    I am not against making obvious corrections; I just believe they need to be done with care, and that usually means not by a single worldwide edit. In many cases there is ample scope to improve map data in the vicinity of the initial object of interest, you can see my other edits around bat bridges here.

    So before making changes to these low usage tags here are the questions I ask myself:
    1. Am I improving the semantic value of OSM by changing a tag?
      If the meaning of a tag is obvious (as this one is) and you do not know of a more widely used alternative leave it alone.
    2. Has the tag been accepted by other mappers?
      If a tag has been added and other mappers have edited the object subsequently, then this implies some degree of acceptance.
    3. Am I fixing something?
      If it ain't broke dont fix it.
    4. Is the tag related to other more widely used tags?
      Often one can recognise that a rarely used tag has properties similar to more commonly used tags (e.g., builder cf. architect; maker cf. manufacturer). Using an existing pattern and extending it is a great way to create new keys/tags because it's easy to work out how they might be used.
    5. Am I clear about the intentions of the original tagger?
      If not I'll ask them or leave it for another day. Our new changeset discussion feature is really valuable for this.
    6. Do I have appropriate knowledge to make the edit?
    7. Should I try and document the usage rather than change it?
      Often a little bit of documentation helps everyone.
    I also try and keep my changesets local, and document what I have changed to make it easy for someone to see what has changed. However, I mainly don't do this kind of thing: the marginal value of adjusting tags is usually tiny compared with active mapping! (It's also not as much fun).

    Choosing the abstraction level of a tag

    Bat bridges are so obviously a niche structure that it immediately made sense to me to continue with the man_made=wildlife_crossing used by the original mapper, particularly as this was already documented. However such a choice is not always obvious.

    In fact a general trend I have noticed in OSM is that it is often a more specific tag which gains acceptance than a generic one. Sometimes this occurs because the use case for the specific tag is very broad and it directly maps onto common ways of describing things. Often a more generic tag actually moves work from data consumers to mappers (for instance bus stops, wind turbines etc), or worse degrades existing semantics. These more generic tags often do work, but usually only with specific editor support (power is a good example). Generic tags tend to be chosen to strongly support a single use case, but OSM data is often consumed in ways people don't imagine, so an apparently more generic tag may hinder some uses.

    I've made this short note because I've noticed a couple of discussions on the tagging mailing list which in my view are tending towards over generalising tags. A couple of examples are: tourism=camping (to include places which are not camp sites) and amenity=fuel (to include all kinds of fuel, rather than just petrol/gasoline/diesel for motor vehicles).

    As I stated above, at the start of this section, finding an appropriate abstraction level for representing data is often difficult even in commercial database design. In my experience people often do not realise that it is possible to describe the same system perfectly accurately using completely different approaches to abstraction. I have found this a fascinating subject for quite a while. The development of tags in OSM provide many interesting examples. BUT, it is a very broad topic which I hope to cover at some stage.

    Conclusion


    Many of these tags are not wrong; on the contrary many represent mappers trying to codifiy how to represent some of the less obvious things we encounter. Removing them without considering this, has the same effect as zapping hedgerows for bats: it reduces diversity in the OSM ecosystem.

    Que pasa en Valdivia, Chile?

    Que pasa en Valdivia, Chile? Tres meses viajando en Chile con datos OSM me ha hecho mimado: de casi todas las rutas puedo ver si están pavimentadas o no, casi todos los atractivos están, hasta hay muchos senderos dentro de los parques nacionales. Pero en Lago Ranco, faltaba asfalto nuevo, después había una carretera larga supuestamente asfaltada, de pura tierra. Y el mismo día, un camino con asfalto no muy nuevo, mapeado como tierra. Llego a Curiñanco, con más errores de asfalto, y no hay el sendero en la reserva.

    En general, alrededor de ciudades universitarias esta re buena la calidad. Pero que pasa en Valdivia?

    Cuando escribí esto, estaba acampado en el camino al parque Oncol. En una media hora, tres personas me preguntaron si esto era bien el camino a Oncol. Este parque sí esta bastante bien mapeado en OSM, así que alguien debería explicarle a los Valdivianos a utilizar nuestro mapa :)

    erst ÖPNV-Mapper Treffen Region VRR, dann Pizza...

    Der Dortmunder OSM-Stammtisch hatte am Sonntag zum "OSM ÖPNV-Mapper Treffen Region VRR" geladen [1]. Neben bekannten ÖPNV-Mappern u.a Axelr, Thoschi, Nakaner, Weide, OEPNV_Achim, M_Kucha und drolbr war auch Herr Emrah Kutlu von MentzDV vor Ort. Leider musste Frau Kleifges vom VRR wegen Krankheit kurzfristig absagen. Nach einer kurzen Vorstellungsrunde führte Herr Kutlu aus, welche Daten derzeit von MentzDV genutzt werden. Danach wurde die Historie der ÖPNV-Taggingschemata mit altes Schema, PTv2, PTv2.1 und 3 erläutert. Axelr hatte Folien mit Beispielen [2] für alle Objekttypen vorbereitet, an Hand deren gemeinsam über einzelne Änderungen des Taggingschemas im Bereich VRR [3] diskutiert wurde. Den Abschluss machte OEPNV_Achim mit der Vorstellung seines Mappingtools VRR EFA/OSM [4]. Nach sechs Stunden reden und diskutieren über Stop_Area, Plattform und Routen wurde in der nahegelegenen Pizzeria das Treffen beendet.

    Zum Schluss möchte ich ganz herzlich Axelr für die hervorragend vorbereiteten Folien, an Ping e.V. für den Raum und die Infrastruktur, M_Kucha für die Getränke und Raumorganisation und allen Teilnehmern für die konstruktive Diskussionen danken.

    Auf Wunsch werden wir in sechs Monaten ein weiteres Treffen anbieten, möglichst wieder in den Räumen von Ping. Wer über weitere Treffen zum Thema ÖPNV-Mappen im VRR informiert werden will, sollte die Wikiseite [5] zur seiner Beobachtungsliste hinzufügen.

    Mapillary をOSMマッピングにオススメする10の理由 / 10 reasons why I recommend Mapillary for OSM mapping

    Japanese / English

    1. マッピングの事前準備が不要

    • 私は旅行や出張で乗り物から外の風景を眺めるのが大好きなのですが、実は風景を眺めながらたいてい建物、道路、河川などを心の中でマッピングしているマッピング中毒者です ;) あなたも普段行かない場所に行ったときにそわそわしたことはありませんか?そんなときの心強い味方が「Mapillary」です。手許に「Mapillary」をインストールしたスマートフォンさえあれば、事前準備無しにOSM編集用の素材として写真を撮影してMapillaryのサーバ上に残すことができます。

    1. No preparation required for mapping

    • I like watching the landscape from public transportation when traveling. Telling the truth, I am always mapping in my mind watching the landscape such as the shape of the building, river, road etc. Yes, I'm an addicted mapper ;) Don't you feel fidget when visiting a place without field-papers where you have never been to? Mapillary can help you in such cases. All you need is a Mapillary installed smart phone only. You can leave materials for OSM editing as photos without preparation.

    車窓の風景/Landscape from a train -車窓の風景 / Landscape from a train (image by Mapillary/CC BY-SA 4.0)

    2. 簡単操作

    • 操作は極めて簡単です。アプリを起動して撮影モード(歩行、自動車(連写)、パノラマ)を選んで写真を撮るだけです。wifiの接続を検知すると自動的にサーバへのアップロードが始まります。通信コストや速度に問題が無い場合は設定により3G回線からでも送信することができます。

    2. Easy to use

    • Operation is super easy. Run a Mapillary app, select shooting mode and take a ptoto. That's all. Mapillary app will upload photos automatically when a wifi connection is detected.

    Mapillary app for android - android向けアプリ / Mapillary app for android

    3. 容量を気にする必要が無い

    • スマートフォンで撮った写真はあっという間にDISK領域を圧迫しますが、Mapillaryのサーバ上に置いておけば容量を気にする必要がありません。ただし、その写真をOSMでの編集に使用するのと同時に、CC BY-SA4.0の下にオープンデータとして公開するのが前提です。

    3. No need to care about local storage capacity

    • Photos taken by smart phone sometimes press storage capacity. But when using Mapillary, you don't need to care about local storage capacity after uploading. But be sure that your photos will be used for OSM editing and licensed under CC BY-SA 4.0.

    4. 写真参照機能がエディタに組み込まれている

    • 例えばiDでは 「 Map Data > 写真の重ね合わせ(Mapillary)」 をチェックすると利用できる写真が金色のアイコンとして撮影方向付きで表示されます。 クリックすると写真が固定表示されるので、既存のマッピングオブジェクトや衛星画像などで位置関係を確認しながらマッピングします。 つまり撮影してアップロードするだけで特別な操作なしにマッピングが始められるのです。

    4. Embedded function for showing Mapillary photos within OSM editor

    • In the case of iD, check "Map Data > Photo Overlay (Mapillary)" . Then, you will see available photos for mapping as gold icons with bearing of the exposure axis. When clicking the icon, you can see a photo and begin editing. In brief, you can start OSM editing after taking photos and uploading without complicated operations.

    Mapillary photos on iD - iDでの表示例 / mapillary on iD

    5. 他のマッピングに再利用できる

    field papersなどを使ったマッピングでは主に自分の興味や目的にフォーカスした地物を紙に書き込んで行きますので、それ以外の地物は記録に残りません。 しかしながらMapillaryで写真として残しておけば自分以外の誰かが同じ写真を見て、まだ地図化されていない地物をマッピングすることができます。 例えば商店街のマッピングをするために撮った写真はバリアフリーに興味ある人なら店舗の入り口や歩道の段差、階段などはとても重要なマッピング対象です。3Dに興味ある人なら建物の階数もマッピングしたいはずです。建物の種別(住居、学校、商業施設、etc)を細かく区分するとその町の人口を、細かいメッシュで推計することにも使えます。

    5. Reuse for other purpose mapping

    When using fiels-papers or a pushpin app, you only record what you want to map. On the other hand, when using Mapillary, you can share photos on iD or Mapillary. Therefore someone else may use the photo for other purpose of mapping such as wheelchair mapping or 3D mapping.

    6. タグ付けできない、あるいは難しい情報の記録

    タグで表現しきれない情報も写真として残るため、エディタやMapillary上で位置情報に紐付く形で閲覧することができます。タグ付けに迷うような場合も、fixmeタグと写真を残すことで、後日自分あるいは他のマッパーがより良いタグ付けをする手助けとなることができます。

    6. Combination with fixme tag

    You can use Mapillary photo in combination with fixme tag when you don't have confidence for the tagging. Some other mappers may be able to improve it.

    7. 時系列

    Mapillaryには同じ位置で撮った写真を時系列でフィルターを掛けてマップ上に表示する機能があります。OSMでは4Dのタグ付け方法はまだ確立していませんが、定点観測のような形で写真として残しておけば将来、時間軸を考慮した4Dマップで利用できる可能性があります。

    7. Time series

    Mapillary has a function to show photos with the use of time-scale filtering. Although the tagging scheme for 4d has not established yet, it would be helpful for future 4D mapping if you leave photos just like a fixed point observation.

    8. 撮影者と編集者の分離

    マッピング・パーティなどでIT技術に詳しくない方にとってOSM編集は独力で続けるのは難しい場合があります。そのような場合、Mapillaryによる写真撮影チームとOSM編集チームを分けることで、参加者の裾野を広げることができます。

    8. Separating photographer from OSM editing role

    Sometimes it is difficult for non-tech persons to edit OSM continuously for themselves when having a mapping party. In such cases, you can expand the range of participants by separating the role for mapping into photographers and editors.

    9.オープンデータの写真として利用できる

    投稿された写真はCC BY-SA4.0でライセンスされるのでオープンデータとしてOSM編集以外にも多方面に活用することができます。

    9. Use as opendata photos

    You can use the uploaded photos for any purpose under CC BY-SA 4.0 license other than OSM editing.

    10.uMap連携

    サーバ上にある画像のURLはMapillary上で取得できるので、imageタグとして登録したり、uMap上のURL付加機能を利用して写真付きのマップを簡単に作ることができます。 以下は写真URLをimageタグとしてOSMに登録し、uMapからOverpass API経由で動的に読み込んだ例です。

    -兼六園(金沢)

    10. Combination with uMap

    You can get the image url from the Mapillary website, so you can add the url as an image tag or add url directly on uMap. Below is a example of combination with uMap and Mapillary photos. Image urls are added onto OSM using an image tag, and POIs are shown via overpass dynamic request.

    • [1] Pascal Neis shows an overview of recent changeset discussions. In the future, more opportunities for discussion should be added.
    • Edward17 created a weekly exercise in Ukraine as well. The current can be found in the forum. (choose your language)
    • Jaisen Nedumpala noticed that the authorities still prefer mainly printed maps in his native India. When he travels in the Panchayat near Koorachundu, he notes that there is not even a survey or cadastral map. To change that, he held a mapping party. In addition to the very extensive report, there are also many beautiful photographs in the article. :)

    Imports

    QAT-Script Downloadbereich ändern...

    Lange das QAT nich mehr angeworfen... :(

    Heute such ich nach den Einstellungen, wo man den Bereich ändern kann: Pustekuchen.

    Meines Wissens war dieses Dingens früher™ im "normalen" QAT-Menü, heute ist es weg. Also weg im Sinne von weg. Das Wiki macht mich nicht schlauer, zum Glück bin ich nur alt und vergesslich aber irgendwann kommt dann doch ein Wiedererkennungseffekt: Qat Script region auswählen (Mauszeiger...).

    Schön wenn man's weiss und auch zufällig sieht/findet. Doof, wenn man keinen Plan hat bspw. weil man das QAT-Script gerade neu entdecken will.

    So sah das TAB übrigens bisher aus, als das Menü noch intuitiv im - tada! - Menü war.

    Short english description: download area is new in the qat-tab on bottom left. See mouse cursor here: https://www.picflash.org/picture.php?key=CX65GM&action=show

    Broadening the Base and Sharing the Enthusiasm

    As I work away at the #MapLesotho initiative (there's a 48 marathon happening as I write) I am also rather proud/gratified/thrilled to have finished grading about 60 assignments submitted by my BA and MA classes in Digital Arts in Humanities at University College Cork.

    OSM Mapping

    The second assignment for both this year was to participate in a choice of OpenStreetMap initiatives. The first was simply to get their feet wet working with their own neighbourhood. For the more adventuresome I introduced the #MapLesotho option. For those looking for a real challenge I set a couple of them working in the Irish Townlands Mapping Project which extended OpenStreetMap editing to use of MapWarper and a few intermediary tools adding a temporal challenge to their work.

    Following some lectures to attempt to impart not just skills but an appreciation of the implication of the tasks that were being undertaken I was hugely gratified by the unique, creative and simply outstanding reflections that they submitted. They got it! and ran with the challenge.

    I am not trying to figure out how I might share some of these exemplary projects. They currently exist on a variety of class blogs that I hope I might point to and reward the superb efforts and spread the word. It's a great experience to be a part of the realisations, discoveries and community engagement that took place and I have to say great pride in the passionate efforts of the students.

    Geomob London

    May 19th #geomob Details

    Great news geomobsters: Ordnance Survey is opening a new innovation hub in Clerkenwell. Even better news - our next #geomob will be held there! I look forward to seeing you all there at 18:30 on the evening of Tuesday, May 19th. While the venue will be new, our format for the evening will be the time-tested norm; 6 speakers will each have 10-15 minutes to present their slides and answer a few questions from the audience. Afterwards we will retire to a nearby pub to discuss. 

    We’re fortunate to already have a great lineup for the evening. We’ll hear from: 

    I hope you agree it’s a strong list of speakers. If you’ll be able to join us please sign up on the lanyrd page so we get an idea of the numbers. 

    If, for whatever reason, you can’t join us on May 19th our next event after that will be on Wednesday July 15th when our friends at the BCS have once again agreed to host us. Signup is now open for the evening. We have a few speakers already, but volunteers remain very welcome.

    As a final point I want to apologise for the crowded conditions at the pub at our last event. It was far from good. Rest assured all efforts are being taken to ensure our choose of pub for the May event works out better.

    I look forward to seeing you all on the 19th of May!

    Situation géographique de TRADEX S.A.

    Il m'est paru nécessaire de situé sur une carte libre les endroits que je fréquente. Et pour commencer : l'entreprise pour laquelle je boss.

    Les services de Tradex S.A. se trouve dans deux bâtiments bien distincts. Ils se trouvent dans la même rue mais distant d'environ 500 mètres. La Direction Générale est bien situé sur la carte. Il ne reste plus que le deuxième bâtiment qui abrite la Direction Commerciale en particulier.

    Недельное задание 2: статистика

    На прошлой неделе по инициативе UkrainianZombie тематическим заданием было исправление ошибок, найденных скриптом Quality Assurance Tool, в Одесской, Николаевской и Херсонской областях.

    Красивых цифр на этот раз не так много, потому что я не знаю, как посчитать количество ошибок в KeepRight. Если кто-то знает, пожалуйста, напишите в комментариях.

    Итак, приняли участие 5 пользователей, которые отправили 16 пакетов правок и внесли более 3000 правок (3029, если быть точным).

    Пока база ошибок KeepRight не обновилась, можете посмотреть местность и оценить количество исправленных ошибок здесь.

    Примечательно, что наименьшая активность - в Николаевской области: там был сделан всего один пакет правок.

    на этой неделе приглашаю помапить железные дороги: тема на форуме.

    Hettings Mose - hvilken vej strømmer vandet?

    Jeg har skrevet et blogindlæg om mit seneste feltarbejde - et besøg til Hettings Mose ved Ganløse Eged. Her er et vandløb, hvor jeg havde min tvivl om strømningsretningen i OpenStreetMap.

    Blogindlægget kommer desuden en tur forbi Mapillary og de Frie Grunddata fra Geodatastyrelsen, herunder et datasæt med strømningsveje.

    Counting cross-border roads

    Hi,

    I would like to count the number of roads crossing a national border in Europe. Obviously this would take a long time to do by hand. Do any of you know of a way to do this in some kind of automated way ? Or know any trail which could show me how to do it ? With OpenStreetMap or through other ways ?

    Thanking you in advance,

    Brasil espelha o Google Maps

    Olá a todos, Essa é a minha primeira postagem no diário visto que prefiro ocupar meu tempo livre traçando pontos aqui no Rio Grande do Sul, principalmente na cidade de Santa Maria. Não é a primeira vez que vejo isso, mas desta vez resolvi postar. Observando o itinerário de uma linha afixada numa folha A4 com uma imagem de satélite do Google Earth dentro de um ônibus observei que ao anunciar o itinerário modificado de uma linha eles chamam a "Estrada Eduardo Duarte" de "Estrada Antônio Inácio de Ávila". Isso é um erro do Google Maps (talvez feito pelos próprios editores do Google MapMaker) e de onde muio provavelmente obtiveram o nome da rua. Uma que depois que conheci o OSM tenho abolido Google Maps da minha vida. Mas fico imaginando o quanto as pessoas são influenciadas pelo Google Maps de tal forma que as inverdades da Google se tornam verdade. Empresas multibilionárias fazem a verdade do mundo. Quando ouço alguém dizer "Ela se separou mas ainda tá com o sobrenome do marido no face", brinco: "Claro. Mudando o nome no Face tá resolvido. Que importa mudar os documentos?!?!?!". Assim é o Google Maps... o que importa se uma rua tem um nome (muitas vezes oficial determinada por lei) se vem "O Mapa" e diz que é outro nome?!?!?! Não vou fazer aqui a caveiro do Google e do Facebook, até porque se estão no topo é porque merecem (ou não!). Mas as pessoas tem que parar para refletir nas versões de mundo do Google Maps e usar alternativas como esse magnífico projeto que é o OpenStreetMap. O mundo precisa do OpenStreetMap!!!! Como não posso mudar o mundo. Aqui sigo eu detalhando a cidade onde moro, um trabalho de formiguinha mas certo que estou fazendo a minha parte para um mundo melhor...

    Floor Boards

    A toolbox isn’t very useful without a floor. Having never put a floor in a box before, I consulted my book, and came away with the following sage wisdom:

    You should make all your bottom boards interlock in some way – butt joints are a Bozo No-No. You can use a simple ship-lap joint[…] Or you can do things the proper way and use a tongue-and-groove joint on your bottom boards.

    — Christopher Schwarz, The Anarchist’s Tool Chest

    I decided to try ship-lap boards because I don’t have a tongue-and-groove plane. I don’t have a rabbet plane either, but I saw people on the YouTubes who said you could make rabbets with just a chisel and a router plane. This technique appealed to me because I’m left-handed, and both tongue-and-groove planes and rabbet planes seemed to be made for right-handed people. Router planes are ambidextrous.

    RouterPlane

    RouterRabbet

    I found one on Ebay that looked especially pretty, so I bought it. As far as I can tell, this is a type 7, meaning that it’s somewhere between 107 and 109 years old. After a bit of trial and error, and a number of goofed up boards, I made some passable rabbets by this laborious method.

    I decided that this was not a fun use of my time, so I bought a rabbet plane.

    RabbetPlane

    I had to get used to doing things right-handed, but I managed. I still had a hard time keeping everything square, but I produced some ship-lapped floor boards for my box. A rabbet plane is much faster than banging things out with a chisel.

    Shiplap

    I got everything fitted and spaced out the way I wanted, and then I got to use my fancy new cordless drill to pre-drill some nail holes.

    drill

    Now that my tool box has a floor, it seems likely that I’m going to have to start over and make a bigger one. I’m accumulating tools faster than I can build a home for them.
