The U.S. Geological Survey (USGS) National Geospatial Program (NGP) provides free, publicly available geospatial data, including high resolution light detection and ranging (lidar) point clouds and derived elevation data, the most comprehensive and up-to-date surface water mapping for the U.S. in the National Hydrography Datasets, as well as a new application capability for custom dynamic mapping.
In recent years, the data types available through this program have experienced fast growth. This session considers how recent data availability on the National Map can support research communities? What new ways to present spatial phenomena have been made available?
This session seeks to explore the following topics:
How may availability of digital elevation models (DEM) and Source Data, including Lidar Point Clouds contribute to support of spatial research?
How is the USGS improving national surface water mapping to meet the needs of researchers and help to answer the country’s most pressing water-related issues?
How does dynamic mapping inform visualization, analysis, and data extraction requirements?
Overall, this session will discuss recent enhancements to the National Map platform and datasets and consider how these improvements will contribute to data usability for to support a diverse set of research and application needs.
