This looks awesome, well done @kylebarron.dev ! Do you think the @developmentseed/raster-reproject piece is general enough that it should be used for other clientside reprojection?

Thank you! Yes the goal was that it would be general enough, but it really requires a WebGL renderer. I can't remember if Leaflet supports that for rasters

I've done something similar with leaflet but reprojecting was always a pain point

Nice work!

something tells me the lonboard basemap refactor will now move forward quickly :P

thanks to this package i was quickly able to integrate it in my Vue package - a package which would be kind of a swiss army knife for all things web maps - mapcn-vue.geoql.in/examples/dec...

the debug output looks really cool haha, I think it's the part I prefer :D am I right if I say that the `delatin` lib is used in this project to generate polygons in order to minimize reprojection error, instead of minimizing terrain mismatch?

yes essentially. I'm minimizing reprojection error instead of distance to the terrain surface
