Updated Basemap Services
Contributions to World Topographic Map, one of the three community basemaps being built and expanded with detailed data from GIS organizations around the world, continue to grow. The latest updates to World Topographic Map include data from the Dutch Kadaster, which contributed airports, buildings, and neighborhood data from its topographic database; the Spanish Instituto Nacional de Estadística and Instituto Geográfico Nacional/Centro Nacional de Información Geográfica, which contributed administrative boundaries, buildings, hydrology, landmarks, parks, and airports data; the Czech Office for Surveying, Mapping, and Cadastre, which contributed administrative boundaries, landmarks, parks, roads, hydrology, building, contours, hillshade, and vegetation data; and British Ordnance Survey, which contributed data for several major cities in the United Kingdom that includes administrative boundaries, neighborhood, railroads, roads, hydrology, vegetation, and landforms data.
