Lab 8 - Exercise 4 Thematic Raster Layer not loading

[dulcetberg]

I'm trying to create the land use map, which I know we've created a million times using other tools, but I can't seem to get to working in maplibre. I tried to load other raster images as well from the notes, and they do not seem to appear.

import leafmap.maplibregl as leafmap

url = "https://github.com/opengeos/datasets/releases/download/raster/nlcd_2021_land_cover_90m.tif"
colormap = {
    "11": "#466b9f",
    "12": "#d1def8",
    "21": "#dec5c5",
    "22": "#d99282",
    "23": "#eb0000",

}
m = leafmap.Map(center=[-100, 40], zoom=4, height="650px")
m.add_basemap("Satellite")
m.add_cog_layer(url, colormap=colormap, name="NLCD Land Cover", nodata=0)
m.add_legend(title="NLCD Land Cover Type", builtin_legend="NLCD")
m

Thanks! That worked perfectly.
