geeViz.getSummaryAreasLib¶

Functions for retrieving common summary and study area FeatureCollections.

geeViz.getSummaryAreasLib provides helpers that return filtered ee.FeatureCollection objects for political boundaries, USFS administrative units, census geographies, buildings, roads, protected areas, and more. Every public function accepts an area parameter (an ee.FeatureCollection, ee.Feature, or ee.Geometry) that is used to spatially filter the result.
