Geologic Map of North America with The National Map base map

http://bit.ly/m97DmX This multi-scale geologic map service is a partial representation of the digital data for the Geologic Map of North America. Geologic units and faults, clipped to the terrestrial extent of North America, are represented here. The major divisions of geologic time (stratigraphic age) are represented with the RGB equivalent of the CMYK color specifications presented in the FGDC Digital Cartographic ...more »

NRCS Soils with TNM Basemap

http://bit.ly/kHLJvX This map uses The National Map base map from the USGS to shows the Soil Survey Geographic (SSURGO) by the United States Department of Agriculture’s Natural Resources Conservation Service. It also shows data that was developed by the National Cooperative Soil Survey and supersedes the State Soil Geographic (STATSGO) dataset published in 1994. SSURGO digitizing duplicates the original soil survey maps. ...more »

Saving TNM Viewer Mashup as ArcMap MXD in 1-click

Create Core Capabilities to Port Context Configurations in TNM Viewer to MXD First the TNM Viewer would need port the services setup and/or turned on (users choice) to JSON – users setup already in the configuration, as well as the user added content. TNM Team recently did this for another service, so the effort to make this a module to be used in this case should be minimized  Then the Port capability would read that ...more »

USGS Earthquake uses TNM data in New Online Base Maps

When a major earthquake event occurs, the earthquake web applications can receives millions of requests for its basemaps. The Earthquake Applications team had 2 major reasons for updating - Maintainability and Performance: Maintainability: The old recent earthquakes mapping interface was built using Generic Mapping Tools (GMT) and other scripting tools that needed to be updated regularly on the server. The system ...more »

Use of TNM Data to Detect Significant Topographic Changes

TNM data (elevation and land cover) have been used to develop a national inventory of significant topographic changes in the U.S. TNM elevation data (National Elevation Dataset) and Shuttle Radar Topography Mission (SRTM) data form a unique pair of seamless multi-temporal elevation datasets that were analyzed to detect 20th century topographic surface changes. An extensive Web site ( http://topochange.cr.usgs.gov/ ) ...more »

Using The National Map Lidar Elevation Data to Study Volcanoes

Light detection and ranging (lidar) point cloud data were used to generate digital elevation models (DEMs) of Mount St. Helens. The high resolution and increased vertical accuracy lidar DEMs are incorporated into the National Elevation Dataset, the elevation layer of The National Map, and are important for studying debris flows surrounding the volcano. The 3D animation of the dome was developed by the U.S. Geological ...more »

TNM LiDAR Elevation Data Employed in Carolina Bay Survey

http://www.cintos.org/Survey/Maps Aerial photographs of Carolina bays taken in the 1930’s sparked research into their geomorphology, but revealed only part of their unique planforms. Digital Elevation Maps, created in Global Mapper using LiDAR-derived data from the USGS’s National Map Server, accentuate the visual presentation of these shallow basins. To support a geospatial survey, the LiDAR maps were exported as KML-JPEG ...more »
