Stamp sand mapping, resources available online

HOUGHTON — Since public awareness and participation are key factors in solving the Gay stamp sand situation, research and interactive stamp sand movement maps have been made available online by researchers at the Great Lakes Research Center (GLRC).

“What we’d really like people to do is go to the page and use it as a resource for the stamp sands,” said Colin Brooks, senior research scientist at the Michigan Tech Research Institute (MTRI) at the GLRC meeting last week.

At, community members can see data from 2016 LiDAR and imagery, an overview of the work.

At, users can interact with the full scope of collected data. The interactive maps use LiDAR, aerial photos and multispectral data to show sand movement over time and key areas of concern.

“We put these remote sensing results on a user-friendly interactive website,” Brooks explained. “It really helps you interpret where the stamp sandbars are and the trough area and the reef itself.”

This data includes previous testing and historical aerial photos. The team was able to digitize the historical photos and data.

The map allows users to zoom in select dates in time and landmarks like the reef or Wolverine mill.

“We encourage people to go visit this site…use it to query data and see the results and the reports that I mentioned are also on there,” Brooks said.
