Display Field:

Type: Group Layer

Geometry Type: null

Description: Contours for display at large scales (1:50,000 and larger) from The National Map. These contours are refreshed every quarter, and are created by USGS TNM for US Topo. Contours are derived from best available data from 3DEP, and are shown on US Topo GeospatialPDF maps. These contours are created separately for each 7.5' 1:24,000-scale US Topo quadrangle, and thus they may not match across quad boundaries. For information about 3DEP, please see
