Mapping the Land - Connected World

With the passage of the Bipartisan Infrastructure Law, one of the largest and most significant investments in rebuilding our roads and bridges since President Eisenhower’s Interstate Highway System, attention has been paid to updating the maps that will show where construction and long-term investments are most needed. To provide this data, the U.S. Geological Survey LiDAR used for USGS mapping

The Accuracy and Consistency of 3D Elevation Program Data: A Systematic Analysis

The 3D Elevation Program (3DEP) has created partnership opportunities to increase the collection of high-resolution elevation data across the United States, eventually leading to complete coverage of high-resolution, three-dimensional (3D) information from light detection and ranging (lidar) data across the entire country (interferometric synthetic aperture radar in Alaska). While 3DEP data are collected at different times and by varying producers, the assumption is that the use of the 3DEP Lidar Base Specification will provide standardized and consistent data across data collections. Another assumption is that the integration of lidar data into the seamless digital elevation models increases the accuracy of the derived products. This study tests these assumptions and updates some of the accuracy metrics that were done on previous versions of the standard products.
