Hikers, backpackers, and hunters consult topographic maps to plot routes for their trips. Maps can show distributions of things over the Earth, such as settlement patterns, and exact locations of houses and streets in a neighborhood.Ĭartographers create maps for many different purposes. They teach about the world by showing sizes and shapes of countries, locations of features, and distances between places. Maps present information about the world in a simple, visual way. TNM Access API - Access to Datasets, Notifications, Products and Services through TNM Access.A map is a symbolic representation of selected characteristics of a place, usually drawn on a flat surface. Hazards Events - Access to hazards event data through the Hazards Data Distribution System (Training Video Lesson 7d). Historical Data Archives - Access our historical imagery and other data through EarthExplorer (Training Video Lesson 7a-c).

Historical maps can also be explored in detail and downloaded via the TopoView Application (Training Video Lesson 9b).ĭirect access is provided via browsable links through our Amazon's Cloud Browse site.įor faster, very large volume access to 3DEP lidar data we also provide a ‘user pays’ options through Amazon Web Services. Also, LidarExplorer can be used for advanced searching and visualization for lidar and digital elevation models (DEMs) data. The map and data products are searchable through the Download Application (Training Video Lessons 4a-d). See our Dataset List for a brief explanation of these products. Lidar point cloud data is also available over many areas of the US.

Raster datasets include: Digital Elevation Models (DEMs), Orthoimagery, and Land Cover. The vector datasets include: The National Hydrography Dataset(s), Watershed Boundary Dataset, Governmental Boundary Units, Transportation, Structures, Elevation Contours and Geographic Names. The Topographic Maps and geographical information system (GIS) data provided in The National Map are pre-generated into downloadable products often available in multiple formats.
