Looking to use these building footprints from Google, and they're in a format I haven't heard of before, a 'spatially sharded CSV'. Has anyone ever worked with this dataset or know how I could read in the spatial data?
Here's more info from the page at Google Research:
Building polygons
Building polygons are stored in spatially sharded CSVs with one CSV per S2 cell level 4. Each row in the CSV represents one building polygon and has the following columns:
- latitude: latitude of the building polygon centroid,
- longitude: longitude of the building polygon centroid,
- area_in_meters: area in square meters of the polygon,
- confidence: confidence score [0.5;1.0] assigned by the model,
- geometry: the building polygon in the WKT format (POLYGON or MULTIPOLYGON),
- full_plus_code: the full Plus Code at the building polygon centroid,
