I've had to build out some version of a geospatial vector embedding / latent variable dataset for at least 4 separate projects now. Come see the viewer I've built on top of it! The embeddings come from globally available Copernicus land cover data.

Can you explain what I’m looking at? I don’t know how to interpret the hex tiles :-)

Great question. A legend or brief description of the underlying logic / heuristic would be helpful.

I'm pretty sure I'm not the intended audience but I also have no idea what this is used for. Surveying? Real estate tycoons? Oil & gas exploration?

How did you generate the embeddings. The vectors are relatively small for all the embedding I have seen built from image and nlp models.

Which copernicus bands were you using? Did you augment the data with DEM info?

Seems to not handle the ocean well.

It's due to the fact that they used satellite imagery to create the embeddings. The map is just for visualization. They probably used 5 or more bands of the satellite data which means each pixel is going to be slightly different due to things like depth, amount of silt in the water, amount of plankton....

Having worked on these types of problems before the model is doing a pretty great job matching pixels.
