Description: Global: Hillshade for land is derived from SRTM 90m (1 Arc Second) between 60 degrees south and north; while GTOPO is used for extreme latitudes. Ocean/coasts tint is derived for the U.S. and Canada from TeleAtlas, and all other from AND. Forest Canopy cover from FAO, obtained from USGS and shown in bands of 10% density, except in lower 48 U.S. States and Hawaii, which use 30m USGS NLCD Forest Canopy in 10% bands. Country boundaries are shown, with largest countries labeled. Sub-national political units are shown, with largest labeled. Largest cities are shown as light orange-beige polygons and labeled. Largest named landforms and marine water bodies are labeled; source is ESRI. In U.S. USGS NHDPLus flowlines are shown based on mean annual flow as determined by upstream drainage; generalized by ESRI. Global freshwater hydrography from AND (Automobile Navigation Data). In the U.S. freshwater bodies are derived from NHDPlus waterbodies and areas, with editing and generalization by ESRI. Road data is from AND, level 0 and 1, generalized by ESRI. Large U.S. National Parks from NPS, and National Forests, state parks, and military bases from TeleAtlas (improved by ESRI).
