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 OpenLayers Viewer Framework

The USGS Center for Integrated Data Analytics - cida.usgs.gov - created this prototype in Summer 2010 for The National Map Viewer Framework in OpenLayers. It calls WMS or Tiled services, in similar style to TNM. To use, extract the attached zip, and double-click index.html. This is a seeder starter OpenLayers prototype to anyone else who wants to download the code and modify. Maybe could go on "github". Recommended ...more »

TNM Services in ArcMap Template

In 2010, the USGS Community for Data Integration had a goal to incorporate new National Map base data layer services in existing mapping applications and document case studies as a demonstration of using these corporate data assets. The attached ArcMap MXD Templates were created as palettes to drag and drop services from this MXD into scientist MXDs to make mashup within ArcMap. For static and stable services, this model ...more »
