Introducing: the AI Georeferencer 🗺️ Our new QGIS add-on generates control points for raster maps automatically, using AI. Here's me georeferencing two maps in QGIS without ever manually adding a GCP:

The AI Georeferencer in QGIS is now publicly available 1. Aerial imagery georeferences to satellite near the QGIS map canvas 2. The full georeferencer reads coordinates, buildings, streets, PLSS, cities, and other features humans use Rotated aerial image support is coming soon

woke up this morning needing to digitize a map... so I spent 65 minutes drawing a USGS quad by hand, then 31 minutes with the AI vectorizer. here's an hour of #QGIS condensed into 60 seconds (top: AI, bottom: hand)

What if LLMs could digitize your survey boundaries for you? Well, they can, and it's in our next AI vectorizer version 😎

I had an amazing conversation with Daniel from the @MapScaping podcast about building custom AI models for #GIS : 4:41 Why build the MVP in @QGIS ? 14:44 How does an AI Vectorizer actually work? 19:55 What would AI georeferencing look like? 25:40 When is an ML model "good enough"?

I thought today's surprise would be seeing this working after building it for what seems like forever 😅 but actually it was waking up to organic usage in one day exceeding my all time usage ... *before* today's launch

GIS devs rarely talk about UX design. But when a user posted to the qgis-user mailing list, I knew my QGIS plugin's design was the real issue 😞 Here's the 5 things I've done as a #QGIS plugin developer to 10x our user experience since that post 🧵👇

@mouthofmorrison right now we reference basemap/satellite imagery as the ground truth but we could change that to any geotiff I guess!

🔥🔥 Super stoked about this new product launch — the blog also dives into the tech stack, from how we choose projections to spinning up a server for every new user.

@wgs084 Apuntamos a una precisión cercana al 0.5% de la resolución original de la imagen, aunque en la práctica puede llegar a ser tan baja como el 5%

@JonnyBear12 yes: 1. ~16MiB file size limit for now and 2. need to make sure the aerial image is approximately north aligned, and you should get good results

1. Be ruthless about eliminating QGIS crashes. Every crash results in lost work and pain for the user (no auto-save!) Often caused by segfaults deep in C++, bad memory accesses can be very difficult to debug in QGIS. Use lldb or valgrind to track them down.

3. Keep plugin load times in the ms. Plugins are reloaded every time someone boots QGIS. If it's slow (like 6s!), that's repeated ad nauseam until they uninstall it. Sub-20 milliseconds is the goal time.

@SteveTypesStuff yes! but currently just north aligned imagery, you may need to rotate it to get good results. rotated imagery support is coming soon

@d_kerkow it should be able to roughly geo reference it yes, especially because road features will likely be similar -- but you're right that its tricky and off nadir imagery will always be more difficult to georeference, because we DO use a reference base map

2. Error messages should answer: WHO, WHY, and HOW ❓ WHO's plugin is giving me this error? WHY did it happen? HOW can I stop it from re-occurring? If you can't answer all three, your error message will do nothing but notify the user something's wrong.

5. Use GitHub code search to learn about API calls While the QGIS docs and source code are amazing, it's very useful to see how other devs designed their code. And because all QGIS plugins are GPL, it's all available! Search your function call on GitHub to learn more 👀

4. Match your plugin UX to the QGIS UX ⌨️🖱️ When you spend a lot of time in a GIS app, you expect consistency in its responses. That means: - escape / backspace / delete have consistent behavior - your settings menu is used as defaults This reduces your plugin's learning curve
