How does TerraPop transform rasters to area-level data?
TerraPop can derive area-level data from raster data by summarizing the values of the raster cells that fall within each geographic unit. Available summary operations depend on the type of raster data. For continuous raster variables (e.g., temperature, precipitation), available operations are minimum, maximum, and mean. For categorical variables (e.g., land cover classifications), available operations are mode and number of classes. For variables related to particular land cover/land use categories, like cropland, available operations are % area and total area.
