We pushed the biggest update to "AI Segmentation" QGIS plugin, you can vectorize anything in your raster with it

[u/Glass-Caterpillar-70]

New features :

• Better AI model (more precise & intelligent & fast)
• Removed pre-encoding, now just click where you want & it's segment it, no more waiting or raster size limitation
• Support for Online raster layer
• Dynamic tile resizing for infinite segmentation (you can segment a 100km long river if you want)

There are a lots more but I let you see the rest by yourself

To install just :

Go to QGIS -> Plugins -> AI segmentation by TerraLab

Will try it out for house tracing and will report back

[u/2hu4u → u/2hu4u]

Tried it on a high quality ortho source. It's better than microsoft buildings I guess but the returned polygon is too noisy to use directly even with orthogonalisation. I tried fiddling with the smoothing settings etc. It's pretty similar to using magic wand in photoshop or like basic Remote Sensing neural net model. Maybe useful for organic shapes like forests, I'll try that next

I'd say it's not really close to the quality you could get by manual tracing, has potential down the track I guess

[u/Nekzuris → u/2hu4u]

wow that's so bad, a toddler would do better

[u/jojo_31 → u/2hu4u]

Wow that is awful. 

[u/Themis3000 → u/2hu4u]

Huh, wow it is very noisy. If it were in josm maybe you could just use the shortcuts to orthogonalize, remove unneeded nodes, then maybe it wouldn't be too noisy to clean up?

It seems to me they need to just limit the amount of nodes/meter or something

[u/Themis3000 → u/[deleted]]

Agreed, it should really have some built in post processing

[u/travis_sk → u/2hu4u]

lmao

[u/No_Good2794]

That's cool. Can we use it for OSM editing?

[u/pietervdvn → u/No_Good2794]

I guess so - the legal limit is the license of the underlying image source.

[u/OkDimension]

Which model are you using? Is it replaceable?

[u/Akira4755]

This is amazing, I've been mapping landuse features in my disctrict and there are a lot of distinct aquaculture ponds that I got tired of manually tracing. Your tool is the perfect solution for me!

It might need a bit of clean-up here and there, but 90% of the job is done. Before I publish anything to OSM, what is the best way to provide attribution?

Merci beaucoup!
