:: About the Land Image Analyst Project

Land Image Analyst was developed by GDA Corp for the USDA Forest Service Chesapeake Bay Program as a land cover recognition tool to aid communities in developing land cover analysis and change detection. It has many applications, such as mapping tree canopy, identifying impervious surfaces, identifying stream buffers, and more.

The Green Infrastructure Center is supporting the Chesapeake Bay Program to promote and support this tool and provide guidance to development, as user feedback and support needs are identified. As part of the project, the GIC will provide regular reports to the developers based on both our own experience and those gathered by engaging users in training and support.
