Description

This map was created from high-resolution elevation data for the Northeastern US region as shown below (New Jersey, New York, Pennsylvania, Maryland, Delaware, Connecticut, Rhode Island, Massachusetts, New Hampshire, Vermont and Maine with partial coverage of Virginia and West Virginia).

Approximately two-thirds of the map was made from bare-earth LIDAR data with a horizontal resolution of 1.2 meters (4 feet). Where this was not available, USGS 3DEP 1/9 arc second data was used with a resolution of 2.4 meters (8 feet). In areas where no LIDAR-based DEM was available, legacy USGS NED 1/3 arc second data is used with a resolution of about 9.6 meters (32 feet).

A three-dimensional version of this map is also available. You must be using 3d view to access the 3d map: click/tap the compass to switch between 2d/3d modes. 3d maps should then appear in blue on the menu. 3d maps use more data and are slower to render, always use the 2d version unless you need 3d views of the terrain.
