Outdated and inconsistent elevation data cost lives and hinder prosperity across our Nation. Current and accurate 3D elevation data are essential to help communities cope with natural hazards, support infrastructure, ensure agricultural success, strengthen environmental decision making and bolster national security.
The USGS, along with other federal, state, local and private agencies is establishing a new 3D Elevation Program (3DEP) designed to respond to the growing needs for three-dimensional mapping data of the United States.
Desde agosto de 2013, cada uno de los 50 estados se han encontrado disponible para editarse dentro del USGS (“United States Geological Survey”, por su nombre en inglés) The National Map Corps (Cuerpo de El Mapa Nacional o “TNM Corps” por sus siglas en inglés), a través del proyecto Voluntario de Información Geográfica.
Concentrations of dissolved solids, a measure of the salt content in water, are elevated in many of the Nations streams as a result of human activities, according to a new USGS study.
US Topo maps now have a crisper, cleaner design - enhancing readability of maps for online and printed use. Map symbols are easier to read over the digital aerial photograph layer whether the imagery is turned on or off.
Want to know how elevation will benefit your state? The USGS National Geospatial Program is advancing the 3D Elevation Program, known as 3DEP, in response to the growing need for high-quality three-dimensional representations of the Nation’s natural and constructed features.
US Topo maps now have a crisper, cleaner design - enhancing readability of maps for online and printed use. Map symbols are easier to read over the digital aerial photograph layer whether the imagery is turned on or off. Improvements to symbol definitions (color, line thickness, line symbols, area fills), layer order, and annotation fonts are additional features of this supplemental release.
