Volunteers earn virtual badges for participating and are recognized for their contributions (with permission) via USGS and The National Map social media.This report presents probabilistic seismic hazard maps for Seattle, Washington, based on over 500 3D simulations of ground motions from scenario earthquakes. Begin editing in your own hometown or anywhere in the U.S., Puerto Rico, and the U.S. “How to” documentation including a comprehensive User Guide and a Quick Start Guide will have you up and editing quickly. It is easy to sign up and get started! All you need is access to the internet, an email address, and a willingness to learn. Topo Maps!Īnyone with an interest in contributing can volunteer. By updating and verifying structures data, volunteers are making significant contributions to USGS National Structures Database, The National Map, and ultimately U.S.
Virgin Islands.Īs part of The National Map, structures include schools, hospitals, post offices, police stations, cemeteries, and other important public buildings. NMCorps is an online crowdsourcing mapping project with volunteers successfully editing structures in all 50 States, Puerto Rico, and the U.S. 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) to provide the first-ever national baseline of consistent high-resolution elevation data – both bare earth and 3D point clouds. We also continue to be ready to meet growing needs for higher quality data, repeat coverage, and new products and services. 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. 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 National Map (TNM) supporting themes include boundaries, elevation, geographic names, hydrography, land cover, orthoimagery, structures, and transportation.

National Map GIS data download and other related applications for working with our topographic data are available on our Data Delivery site. Other types of georeferenced or mapping information can be added within The National Map Viewer or brought in with The National Map data into a GIS to create specific types of maps or map views and (or) to perform modeling or analyses. Data sets and products from The National Map are intended for use by government, industry, and academia-focusing on geographic information system (GIS) users-as well as the public, especially in support of recreation activities. The National Map also serves as the source of base mapping information for derived cartographic products, including 1:24,000 scale US Topo maps and georeferenced digital files of scanned historic topographic maps.
The majority of The National Map effort is devoted to acquiring and integrating medium-scale (nominally 1:24,000 scale) geospatial data for the eight base layers from a variety of sources and providing access to the resulting seamless coverages of geospatial data. The geographic information available from The National Map includes boundaries, elevation, geographic names, hydrography, land cover, orthoimagery, structures, and transportation. The National Map is easily accessible for display on the Web through such products as topographic maps and services and as downloadable data. Nationally consistent geospatial data from The National Map enable better policy and land management decisions and the effective enforcement of regulatory responsibilities. Customers can use geospatial data and maps to enhance their recreational experience, make life-saving decisions, support scientific missions, and for countless other activities. The National Map supports data download, digital and print versions of topographic maps, geospatial data services, and online viewing. The National Map embodies 11 primary products and services and numerous applications and ancillary services. The National Map is a suite of products and services that provide access to base geospatial information to describe the landscape of the United States and its territories.
