GLARS Announces Public Release of SharedGeo’s Great Lakes Digital Surface Model Products

May 12, 2022 No Comments by central

The Great Lakes Alliance for Remote Sensing (GLARS) announced today the public release of the Digital Surface Model (DSM) products SharedGeo has created for the Great Lakes. Covering 85% of the Great Lakes Basin, the DSMs were created from over 70 TB of Digital Globe stereo-pair imagery obtained from National Geospatial-Intelligence Agency’s (NGA) NextView program.

In addition to the substantial science required to produce the SharedGeo DSMs, the effort is significant in at least three other ways.

  1. It is the first public domain release of DSM products covering an expansive area (eight states and two Canadian provinces) outside of the polar regions,
  2. It demonstrates the potential for units of government to have access to frequently acquired DSM data without the high cost of similar LiDAR products, and
  3. Because this approach relies on satellite imagery that is being frequently collected, short period, time-sequenced visualization of climate change impact, and the results of mitigation are possible.
