The US Fish and Wildlife Service had to engage a variety of residents, government officials, action groups, and other stakeholders to consider proposed changes to the flow of a major watercourse. An interactive 3D map proved to be a great way to help the various stakeholders find the specific information they needed and see the situation from everyone’s point of view. We also made sure there was an easy way for the USFWS to update the information available as the situation changes and develops.
