Data sources¶
VoxCity integrates many open geospatial datasets. This reference lists the datasets available for each layer of a city model — building footprints and heights, tree canopy height, land cover, and terrain elevation — together with their coverage, resolution, and provenance.
For guidance on choosing between these sources, see the Choosing data sources guide.
