What happened to the Gridfloat, ArcGrid, and IMG formats for elevation data in The National Map?
USGS elevation data available through The National Map was converted to Cloud Optimized Geotiff (COG - GeoTIFF) format in mid-December, 2019. This change was made to improve product processing time, storage, and to support new and evolving cloud processing capabilities.
GeoTIFF is a widely supported raster format and is directly useable by most commercial software that reads or processes Digital Elevation Model (DEM) data. GeoTIFF DEMs will fit seamlessly into most workflows.
Instructions and translator scripts for converting from GeoTIFF to FLT format (Gridfloat) and for converting GeoTIFF to IMG format can be found on the Raster Conversion page.
For additional questions, please send an email to our National Map Help Desk: tnm_help@usgs.gov.

Light Detection and Ranging ( lidar) is a technology used to create high-resolution models of ground elevation with a vertical accuracy of 10 centimeters (4 inches). Lidar equipment, which includes a laser scanner, a Global Positioning System (GPS), and an Inertial Navigation System (INS), is typically mounted on a small aircraft. The laser scanner transmits brief pulses of light to the ground...

The USGS 3D Elevation Program (3DEP) is in the process of collecting high-quality lidar and IfSAR (for Alaska) coverage for all of the United States and its territories. As this new data becomes available, legacy Digital Elevation Models (DEMs) are being systematically replaced with high-resolution DEMs produced almost entirely from the lidar and ifsar data. Legacy DEMs were produced from...
