Improving the Nation’s Elevation + Data • The NGTOC provides operational support for the acquisition, quality control, product generation and distribution of 3D Elevation Program (3DEP) products • In 2015 new elevation products became available through The National Map, including: – lidar point cloud – Ifsar generated digital surface model and orthorectified radar intensity image – 1-meter standard DEM
+ Lidar Point Cloud Digital Surface Model Orthorectified Radar Image
+ Standard DEMs Nationally seamless DEMs continue to be updated with new 3DEP data
+ The National Map - Hydrography
+ The National Map - Hydrography NHD • Advanced relational/feature- based data model • Continuous updates through a network of other Federal and State Data Stewards • Analytical capabilities inherent in flow network/linear referencing • Integrated with Watershed Boundary Dataset
+ National Hydrography Dataset (NHD) • Surface water component of The National Map • General mapping and analysis of surface-water systems • Seamless digital vector dataset for GIS use • Features: lakes, ponds, streams, rivers, canals, dams and streamgages. • Flow network - tracing water downstream or upstream. • Addressing system: Reach codes and linear referencing – link - water discharge rates, water quality, fish population, etc. • Scale: Medium (1:100,000-Scale) High (1:24,000-Scale) • Maintenance: Partnership - Stewardship Model – EPA, FS, State & Local partners
+ The National Map Corps: Making Use of the “Crowd” to Improve Authoritative Data Sources • Supports TNM & US Topo Maps • Volunteers collect point “structure” features • Reward and QA hierarchy systems in place • Studies show excellent data quality • Future: mobile data collection, additional features http://nationalmap.gov/TheNationalMapCorps
