USGS National Hydrography Dataset (NHD) Instance of TNM Viewer

http://viewer.nationalmap.gov/nhd The National Hydrography Dataset (NHD) is the surface water component of The National Map. The NHD is a digital vector dataset used by geographic information systems (GIS). It contains features such as lakes, ponds, streams, rivers, canals, dams and streamgages. These data are designed to be used in general mapping and in the analysis of surface-water systems. The NHD created an ...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 »

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 »

View the USGS Vegetation Characterization Program's data in TNM

The USGS Vegetation Characterization Program has begun web enabling all their National Parks Vegetation data sets via the OGC WMS standard. A new link "View in TNM" will be added to each parks web page. When invoked the TNM Viewer will open and zoom to the vegetation web mapping service. This will provide the researcher with an idea of what each data set has to offer without having to first download the data and bring ...more »

Delineating Watershed Boundaries Using The National Map

The National Elevation Dataset, the elevation layer of The National Map, is the framework for a multi-layered hydrologic database called the Elevation Derivatives for National Applications (EDNA). Using valuable flow direction characteristics within the EDNA, an elevation-derived watershed tool is available to delineate and download watershed boundaries by selecting a point anywhere within the conterminous United States. ...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 »

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 »
