Also, the National Map adds land cover and geographic names, which are not included among the NSDI framework themes. Explore and access published geoscience maps and reports from the National Geologic Map Database (NGMDB). A 2002 report of the National Research Council identified the National Map as the most important initiative of USGS’ Geography Discipline at the USGS (NRC, 2002). The basic elements have been in place for a while — national data themes, data access and dissemination technologies such as The data themes included in the National Map are shown in the following table, in comparison to the NSDI framework themes outlined earlier in this chapter. As you see, the National Map themes align with five of the seven framework themes, but do not include geodetic control and cadastral data.

Popups are small boxes containing text that appear when marker icons are clicked. Add the tiled overlay for the Point locations, that appear on the map as icons, may be added to a base map using a marker overlay. Parameters Usage; category: Dataset categories used for product search. An official website of the United States governmentA number of map services are offered through The National Map (In Leaflet, a map layer is used to display a specific dataset. These data serve government, public and private sector needs for a wide range of activities that include flood hazard mapping, precision agriculture, infrastructure planning and development, natural resource management, environmental assessment and a host of other applications.NMCorps is an online crowdsourcing mapping project with volunteers successfully editing structures in all 50 States, Puerto Rico, and the U.S. Virgin Islands.Anyone with an interest in contributing can volunteer. As one of the cornerstones of the U.S. Geological Survey's (USGS) National Geospatial Program, The National Map is a collaborative effort among the USGS and other Federal, State, and local partners to improve and deliver topographic information for the Nation. At meetings each year (including the annual Provides access to more than 100,000 geologic maps and other types of geoscience reports and data published from the early 1800s to the present day, by the USGS, the State Geological Surveys, and hundreds of other organizations. The Elevation Point Query Service returns the elevation in international feet or meters for a specific latitude/longitude (NAD 1983) point from the USGS 3DEP 1/3 arc-second layer hosted at the NGTOC. (USGS) map. Map layers are organized by group. Executive Order 12906 decreed that a designee of the Secretary of the Department of Interior would chair the Federal Geographic Data Committee. Other types of georeferenced or mapping information can be added within TNM Viewer or brought in with TNM data into a GIS to create specific types of maps or map views and (or) to perform modeling or analyses.The 3D Elevation Program (3DEP) is managed by the USGS National Geospatial Program on behalf of the broader community with a goal of complete acquisition of nationwide lidar (IfSAR in AK) in 8 years to provide the first-ever national baseline of consistent high-resolution elevation data – both bare earth and 3D point clouds – collected in a time-frame of less than a decade. The following sections of this chapter and the one that follows will describe the derivation, characteristics, and status of the seven NSDI themes in relation to the National Map. The National Map - Elevation Point Query Service. In this example, site locations are included for selected wells in the Instructors and contributors: Jim Sloan, Senior Lecturer, John A.

We also continue to be ready to meet growing needs for higher quality data, repeat coverage, and new products and services. Their usefulness is so broad that geologic maps are the most requested scientific product produced by state and federal geological surveys (see The National Geologic Map Database (NGMDB) is the primary source for geologic map and related geoscience information of the United States. Bathymetric contours are shown in blue or black, depending on their location.
At the The National Geologic Map Database has since 1995 been a collaborative effort between the USGS and AASG.
