CountryMercatorTiles
¶
Bases: MercatorTiles
MercatorTiles specialized for country-level operations.
This class extends MercatorTiles to work specifically with country boundaries. It can only be instantiated through the create() classmethod.
Source code in gigaspatial/grid/mercator_tiles.py
create(country, zoom_level, predicate='intersects', data_store=None, country_geom_path=None)
classmethod
¶
Create CountryMercatorTiles for a specific country.
