Vom 2. bis 3. Juli fand in Salzburg die jährliche AGIT-Konferenz für Geoinformatik statt. Unter dem Motto „Shaping Geospatial Futures“ versammelten sich mehrere hundert Besucherinnen und Besucher aus dem deutschsprachigen und internationalen Raum. Auch wenn ich nicht jedes Jahr dabei war, zeigt ein Blick in meine Unterlagen: Mein erster Beitrag auf der AGIT (ein Poster) stammt aus dem Jahr 2005. Ein 20-jähriges Jubiläum also? Verrückt, wie die Zeit vergeht. In diesem Jahr hatte ich die Gelegenheit, die Ergebnisse der Masterarbeit von Pauline Radu zu präsentieren. Im Wintersemester hatte sie sich im Rahmen ihrer Abschlussarbeit mit Daten des Landeskriminalamts Rheinland-Pfalz beschäftigt. Mit dem Titel ihrer Arbeit: „Möglichkeiten und Potenziale von Retrieval-Augmented Generation für die räumliche Analyse von Kriminalitätsdaten“ konnte somit ein hochaktuelles und praxisnahes Thema in Salzburg gezeigt werden.
Anbei ein Auszug aus der Publikation ihrer Arbeit: “Die steigende Komplexität und Sensitivität der Kriminalitätsanalyse erfordert innovative Ansätze, um präzise Einblicke zu gewährleisten. Dieser Beitrag untersucht das Potenzial der Retrieval-Augmented Generation (RAG) für die Analyse von Kriminalitätsdaten unter besonderer Berücksichtigung deutschsprachiger Texte. RAG integriert fortschrittliche Natural Language Processing (NLP) Techniken mit Retrieval-Modulen, um kontextreiche Antworten auf spezifische Fragen zu generieren. Anhand eines prototypischen RAG-Systems, implementiert mit polizeilichen Falldaten aus Rheinland-Pfalz, werden Möglichkeiten und Herausforderungen für die räumliche Analyse untersucht. Ergebnisse zeigen, dass das System präzise in der Identifizierung von Tatort-Hotspots und der Analyse von Deliktmustern agiert, jedoch Herausforderungen in der Konsistenz und Abdeckung räumlich breiter Phänomene aufzeigt. Durch Feintuning und verbesserte Datenintegration könnte RAG zukünftig eine robuste Unterstützung für die Kriminalitätsanalyse bieten.” Der Fulltext des Beitrags ist unter folgender DOI zu finden: doi.org/10.25598/agit/2025-14
Ein kleines Augenzwinkern am Rande: Mein Vortrag begann mit dieser provokanten Folie – „RAG is dead. Long live agentic retrieval!?“ Mit dieser Aussage wollte ich auf die rasante Entwicklung im Bereich der KI-basierten Informationssysteme anspielen. Während RAG in vielen Anwendungen noch als innovativ gilt, wird in der Forschung bereits über den nächsten Schritt diskutiert: sogenannte „agentic retrieval“-Ansätze, bei denen autonome Agenten gezielt, adaptiv und kontextsensitiv Informationen beschaffen. Ob es sich dabei nur um ein Buzzword oder um den Beginn einer Paradigmenverschiebung handelt? Wir werden sehen
Vielen Dank an dieser Stelle für das positive Feedback und die Fragen im Anschluss und in den Kaffeepausen – hat mich wirklich gefreut.

Seit dem Frühjahr 2020 gibt es in Deutschland ein neues Verkehrszeichen: den Grünpfeil nur für Radfahrende. Es erlaubt Radfahrenden, auch bei roter Ampel nach rechts abzubiegen. Ich habe mich gefragt, ob ich mit Hilfe von OpenStreetMap automatisch Stellen raussuchen kann, bei denen die Aufstellung so eines Zeichens sinnvoll wäre.
Wo sind solche Zeichen sinnvoll?
Wenn ich meine persönliche Erfahrung und die gesetzlichen Vorgaben (StVO, VwV-StVO) zusammennehme, ist der Grünpfeil für Radfahrende vor allem in dieser Situation sinnvoll: Wenn ich aus einer Wohnstraße komme (kein Radweg vorhanden) und rechts auf eine Straße einbiegen will, die einen abgetrennten Radweg hat. Da ich hier nur auf querenden Fuß- und Radverkehr achten muss, ist ein sicheres Abbiegen nach rechts auch bei rot in der Regel möglich.
Overpass-Query finden.
Ich will die Abfrage nicht zu kompliziert machen, aussortierne kann ich ja immer noch. Ich will also wissen, wo Ampeln auf Wohnstraßen stehen, bei denen im Umkreis von 10 Metern ein Radweg oder ein getrennter Rad-/Fußweg existiert.
Die gesuchten Merkmale lassen sich so in OSM-Tags fassen:
Die Ampel ist ein node mit highway=traffic_signals
Sie liegt auf einer way mit highway=residential
In der Nähe (max. 10 m) existiert ein:
way mit highway=cycleway
oder
way mit highway=pathundbicycle=designatedundsegregated=yes
Mithilfe von ChatGPT (ja, ich weiß, aber ich finde die Overpass-QL echt schwierig), habe ich diesen funktionierenden Query gefunden:
[out:json][timeout:25];
// 1. Wohnstraßen und zugehörige Ampeln
way["highway"="residential"]({{bbox}})->.residentials;
node(w.residentials)["highway"="traffic_signals"]->.signals;
// 2. Radwege nach OSM-Tagging-Standards
(
way["highway"="cycleway"]({{bbox}});
way["highway"="path"]["bicycle"="designated"]["segregated"="yes"]({{bbox}});
)->.cycleways;
// 3. Finde Ampeln, die innerhalb von 10 m zu einem Radweg liegen
node.signals(around.cycleways:10)->.relevant_signals;
.relevant_signals out center;
Als nächten Schritt werde ich die Ergebnisse für meine Heimatstadt auswerten (tatsächliche Eignung mithilfe von Mapillary oder Sichtung vor Ort prüfen) und anschließend bei der Verwaltung anregen, an diesen Stellen diese Schilder aufzustellen.

J’ai eu l’honneur de participer en présentiel à la première conférence State of the Map Global 2024 organisée en Afrique, au Kenya. Cette expérience a été marquante et enrichissante, me permettant de rencontrer de nombreux acteurs passionnés engagés dans divers projets. Bien que je sois la seule représentante du Bénin, je me suis sentie pleinement intégrée dans cette dynamique internationale. Retrouver des amis de la communauté Wikimedia à SotM a été une agréable surprise.
Les sessions, présentations et ateliers étaient d’une qualité exceptionnelle. Bien que je n’aie pas animé d’atelier cette fois-ci, je suis plus déterminée que jamais à le faire lors des prochaines éditions. J’ai particulièrement apprécié les interventions sur l’égalité des genres, notamment celle d’Anastazia Caroll sur Women in OSM Tech, ainsi que celle de Bénédicta, qui a mis en lumière les perspectives de la participation des femmes dans OpenStreetMap.
La réunion des membres votants de HOT m’a permis de rencontrer le président et d’autres membres de l’organisation. Ce fut une occasion précieuse d’échanger des idées et de mieux comprendre les dynamiques internes de HOT. Ces interactions ont renforcé mon engagement au sein de la communauté et m’ont permis de nouer des relations professionnelles significatives.
Je tiens à exprimer ma profonde gratitude à OSM Kenya et au groupe de travail de SotM pour l’organisation exceptionnelle de cet événement, ainsi qu’à HOT pour m’avoir accordé cette bourse qui m’a permis de vivre cette expérience unique. Un immense merci également à l’équipe organisatrice et aux bénévoles, qui ont fait de cette conférence un véritable succès.
Je suis pleinement motivée à poursuivre mon engagement et à jouer un rôle plus actif lors des prochaines éditions.

Contributed to the preparation of survey reports*, integrating observations, geospatial data, and recommendations for planning documentation.
Skills Applied
Georeferencing and symbology in GIS
AutoCAD drafting and technical alignment
Thematic layering and map production
Field coordination using QField and GNSS tools
Formal report writing and spatial data interpretation
Today’s tasks deepened my understanding of how surveying and cartographic techniques drive transmission infrastructure planning. The integration of GIS with field activities reaffirmed the importance of spatial accuracy in energy distribution networks. I was particularly engaged with the line diversion analysis, which challenged both technical reasoning and spatial decision-making. I continue to learn from my mentors and refine my approach to precision mapping and collaborative survey documentation.

bin neu hier und habe etwas in der Karte entdeckt, was so nicht richtig ist, bzw. den wahren örtlichen Gegebenheiten entspricht.
Diese Punkt-Stichlinie zeigt wohl einen “Fußweg” an.
Bei dem Teilstück von der Hauptstrasse kommen in Richtung Waldstück neben der 2a, handelt es sich um eine private Zufahrt, also Privatgrundstück (nämlich meins), zum Haus.
Bei dem “Fußweg” handelt es sich ebenfalls um ein privates Grundstück.
Es ist leider so dargestellt das man dort durchfahren/ durchgehen kann.
Das geht nicht: dort befindet sich eine feste Absperrung.
Zumal es sich hier um private Grundstücke handelt, wo der allgemeine und öffentliche Zutritt nicht erlaubt ist.
Es verursacht hier sehr unschöne Probleme, weil sich Menschen auf dieses Kartenmaterial berufen.
Ich würde mich sehr freuen, wenn hier jemand ist, der das zeitnah korrigieren kann.
Vielen Dank

Climate change and increasing urbanization are causing more and more heat, which is particularly noticeable these days. Locals and tourists are therefore looking for ways to avoid direct sunlight. Of course you can change sides of the road, but this is not always possible – and Google Maps doesn’t offer any help.
The “vampire routing” proof-of-concept, also known as “vampire mode”, solves this problem with a new type of technology. It suggests footpath routes that preferably run in the shade – just like vampires that avoid the sun at all costs. A small detour can also be accepted.
The benefits are manifold: City residents and tourists benefit from cooler routes in summer. City administrations can supplement their heat reduction strategies. And tourist destinations receive a tool to improve quality of life and visitor management at the same time.
The innovative application was developed by a team of software engineers led by Professor Stefan Keller from the OST – Department of Computer Science at the Rapperswil-Jona campus. It combines methods from geoinformatics, climatology and spatial planning. The core of the proof of concept consists of a combination of open data and open source software. The footpaths, for example, come from OpenStreetMap, the world’s leading source of open map data, which is also used by emergency services. The shadow was calculated from point cloud data from swisstopo (swissSURFACE3D). This was used to simulate the shadows cast by buildings and trees on footpaths for a specific time of day. These and other criteria are incorporated into the OSM traffic network and the application’s footpath graph.
As a demonstration, the “vampire mode” was implemented for the area of the city of Zurich on August 1 at 16:00 and made available on the servers of SOSM. Radio SRF 1 (in the Regionaljournal ZH/SH), SRF 3 and SRF online reported on this on July 1 and 2, 2025.
Future versions could take into account hourly sun positions or paths with a slight incline and thus further increase the added value. We are happy to invite tourism professionals and other cities to cooperate with us in order to bring the application to other regions.
Go to the website https://routing.osm.ch. Select “Foot (vampire)”, enter the start and end (both must be within the city of Zurich) and the coolest route will be displayed.

Не высокая частота обновления спутниковых снимков, не всегда позволяет добавлять новые здания. В этой ситуации можно воспользоваться схемами с паспортов строек.
При перерисовке схемы возникает проблема, состоящая в том, что фотографии схем содержат искажение перспективы, которое надо как то исправлять. Ниже предложен не сложный способ того, как можно это сделать с помощью растрового графического редактора GIMP, векторного - Inkscape, а так же JOSM с установленным плагином ImportVec.
На первом изображении видно искажение перспективы возникшее в результате отклонения фокальной плоскости фотокамеры относительно плоскости схемы стройки.
Загружаем изображение в редактор GIMP, и в меню “Вид” включаем отображение сетки
Далее с помощью инструмента 3D преобразование или Перспектива, совмещаем прямоугольные границы рамки паспорта, с направляющими сетки так, что бы горизонтальные линии плаката совпали с горизонтальными линиями сетки, а вертикальные, с вертикальными. Для наклона изображения следует зажимать клавишу Ctrl. В результате мы должны получить вполне правильный прямоугольник. После этого, можно обрезать лишние края, и добавить контрастности изображения для увеличения чёткости линий.
Тут важно отметить, что на фото обязательно должен быть виден весь паспорт, а не только его часть со схемой, поскольку выравнивание происходит по прямоугольной форме края его рамки.
Сохраняем изображение, и открываем его в редакторе Inkscape. Теперь необходимо обвести контуры здания. Так же следует обвести контуры уже существующих зданий, границ и дорог, для того что бы по этими линиями можно было привязаться к уже существующим объектам карты в JOSM. Сохраняем результат в SVG, не забыв перед этим удалить из файла растровую подложку.
Загружаем в JOSM данные OSM интересующего нас участка
Далее, поверх него создаём новый пустой слой, и перетаскиваем (d&d) на него полученный SVG файл. Как видно на скриншоте, масштаб и положение линий не совпадают со слоем загруженных данных.
Теперь выделяем все линии, и с помощью масштабирования, и поворота, добиваемся совмещения линий дорог и зданий которые мы обвели, с уже существующими объектами карты, и фотоподложки.
Выделяем контур интересующего нас здания, копируем его ( ctrl+c), и переключившись на слой с данными OSM вставляем (ctrl+v). Контур будет вставлен в редактируемый слой, но не на то же место где он находился в его родном слое. Это легко исправить простым перетаскиванием, до совпадения с полупрозрачным контуром этого же объекта в другом слое, где мы его выровняли. Остаётся добавить тэги, и выгрузить данные в OSM.
Таким способом можно достаточно просто и быстро переносить данные со схем строящихся зданий, дорог и других объектов.

I’m continuing my effort to capture 360° images of the city of Salzburg for use in Mapillary and Panoramax. The goal remains the same: improve OpenStreetMap data, especially in areas with unresolved notes where better visual context can help.
Progress So Far
Here’s the current state of coverage from my 360° image collection:
My Route Planning Setup
To plan my routes, I’ve been using OSMAnd’s built-in GPX recording and map display. This allows me to see where I’ve already been and make instant decisions on which streets to cover next - without having a router trying to direct me back on track constantly.
I can also choose freely whether to ride on streets, paths, or cycleways depending on conditions. This flexibility has proven much more practical than relying on pre-planned routes.
Managing Photos for Upload
On the photo management side, I’ve kept my setup from last time: using the command-line tools from both Mapillary and Panoramax. They continue to work flawlessly and are far more stable and efficient than the GUI options.
However, I still need to manually filter the images - removing duplicates taken at traffic lights, while standing still, or checking my phone. It’s a bit of work, but it ensures that the uploaded sequences are clean and useful. I’m not sure i want this with the video-mode - but with the new mounting it might be worth a try.
What’s Changed Since the Last Post
One major improvement: I switched from a helmet-mounted camera to a selfie stick mounted directly on my bicycle. This setup means I can now look around naturally (better safety) while riding without affecting the camera’s field of view.
Additionally, I’ve started adding a nadir - a small branded graphic at the bottom of the image that hides the mounting point and promotes our local OSM club. I followed the excellent guide by Trek View to make this happen.
The fixed camera mount provied useful so far. The image quality more consistent, but I also feel more comfortable riding. My bike has a bit of an unusual frame, which made mounting the selfie stick with clamps surprisingly easy.
What’s Next?
My goal remains ambitious: to capture all of Salzburg, street by street, and make the imagery available to everyone through Mapillary and Panoramax. I believe this kind of street-level imagery can benefit the entire OSM community—locally and beyond.
If you have ideas, tools, or workflows that might help, I’d love to hear them. And if you’re local and want to collaborate, let’s connect!
Dear OSM Community and Team,
Is there any possibility of accessing a newer imagery layer, such as Maxar? The current Bing Maps Aerial imagery appears to be significantly outdated, which makes it challenging to accurately update or edit map content.

I see many diaries on OSM, but unfortunately the good ones are hard to find, if they can be found at all.
In this diary, I offer some perspectives, without any technical pretensions, but just for the thinking of “what it might look like” in the vein of “Reimagining the OSM.org” or “Better-osm-org” but without the technical side.
This diary is a proposal, a reflection. Its aim is

This diary is a proposal, a reflection. Its aim is to offer a vision of what diaries might look like in the future.
Observation
Many diaries published by the community are interesting, not all of them are, but those that are would benefit from being discovered and promoted to a wider audience.
Diaries are not discoverable from osm.org. When a diary is discovered, it is almost exclusively through direct sharing via an OSM communication channel (forum, Telegram, Discord, etc.).
The aim is to offer ways to find interesting diaries more easily, to know which ones the community values or finds interesting.
Proposal
Categorise
Allowing diaries to be categorised offers several advantages:
Easier to identify the topic(s) of a diary
Have a list of diaries talking of a specific topic
Easier to find a specific diary
A category would group together several diaries addressing the same theme.
This categorisation might be done in the form of keywords, for example: #tutorial #josm #streetcomplete #sotm #telecom #esri.
Add upvotes
To enable the community to highlight the diaries that have generated the most interest and that they found most useful, it would be possible to add a like (or a downvote or an emoji reaction) to a diary.
The same options for comments might be used to highlight the comments most appreciated by the community.
This system would be very similar to GitLab for issues, or Reddit for content.
Diaries search
Once the keyword categories are in place, followed by the community’s reactions to the diaries, it will be possible to explore the diaries according to different criteria: by category, by reactions, by comments, by creation date, or even by location.
“Community Diaries > Share” a landing page for diaries
“Community Diaries > Explore” a page for curating diaries
This is my my second day into the field of OSM, i went back and edited my home grown plce, yuh my home village and and waiting to welcome any reviews because i believe it is the right think to do and am welcoming any mistakes and am hoping to add many more places on the OSM today
I went ahead and edited my villages by adding the various buildings and trees that haven’t been mapped yet

J’ai eu l’honneur de participer en présentiel à la première conférence State of the Map Global 2024 organisée en Afrique, au Kenya. Cette expérience a été marquante et enrichissante, me permettant de rencontrer de nombreux acteurs passionnés engagés dans divers projets. Bien que je sois la seule représentante du Bénin, je me suis sentie pleinement intégrée dans cette dynamique internationale. Retrouver des amis de la communauté Wikimedia à SotM a été une agréable surprise.
