Companion notebook for the Lonboard tutorial in PlanetaryComputerDataCatalog. Walks through interactive raster and vector visualization of Planetary Computer data: STAC search, RasterLayer.from_stac, opacity and colormap adjustments, raster + vector layer composition. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The notebook used lonboard.experimental.RasterLayer.from_stac, which does not exist in any released lonboard. Rewrite around lonboard's shipping strength — GPU vector rendering — using Microsoft Building Footprints: read a STAC GeoParquet quadkey partition into a GeoDataFrame, render hundreds of thousands of polygons with PolygonLayer, then color by meanHeight via apply_continuous_cmap. No tile server; geometry streams as Arrow. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
