6602.2 - U.S. Geological Survey 3D Elevation Program: Past, Present and Future

Thursday, July 6
3:10 PM - 3:30 PM
Location: Delaware B

The U.S. Geological Survey (USGS) has a long history of generating and distributing elevation data. That work is continuing through the 3D Elevation Program (3DEP). The primary goal of 3DEP is to systematically collect enhanced elevation data in the form of high-quality light detection and ranging (lidar) and interferometric synthetic aperture radar (ifsar) data. Preparing for 3DEP required the assimilation of existing elevation data into the suite of 3DEP products, including the National Elevation Dataset. Additionally, all available data were incorporated into the National Spatial Data Infrastructure. Other work included designing a system to handle the expected large volumes of data. This system is currently in place, and is rapidly expanding processing capacity for quality control, product generation and distribution.


Quality control and product generation occur at the National Geospatial Technical Operations Center (NGTOC). After the quality control process has determined the dataset meets the USGS Lidar Base Specification, high resolution elevation data are processed to produce or package ten unique products for distribution via The National Map including high resolution Digital Elevation Models, Digital Surface Models, Orthorectified Radar Intensity Imagery and Lidar Point Cloud data in the form of LAS. Distributed products will be described in detail, as well as how they can be accessed via The National Map.


Near and long term enhancements are planned to increase both the processing capability of elevation data at NGTOC, as well as to offer expanded methods for public access of these data. Operational workflows are continually being assessed for efficiency and updated within an Agile development environment. Data accessibility enhancements include refinement of existing products, data hosting in the cloud, and new or improved elevation services.
