Historical Topographic Maps - Preserving the Past
National Geospatial Program
The USGS National Geospatial Program (NGP) provides vital, trusted topographic mapping information for the United States through The National Map. NGP’s broad portfolio and cross-cutting initiatives span from emergency response support to cutting edge geospatial research. The American people rely on NGP’s publicly available products and services to remain informed and to stay healthy and safe.
The National Map
The National Map, a suite of geospatial products describing the Nation’s topography, is built through NGP’s portfolio and cross-cutting initiatives in concert with public, private, and non-profit partners.
3D National Topography
The 3D National Topography Model initiative (3DNTM) will update, improve, and integrate USGS elevation (3DEP) and hydrography (3DHP) data to support the most demanding scientific requirements and enable data-driven decisions.
USGS Topographic Maps
NGP continues the legacy of USGS topographic mapping by producing US Topo maps, OnDemand Topo maps, and the Historical Topographic Map Collection (HTMC).
