The Lakebed Alteration Decision Support Tool (LADST) is a research project to develop software and data to assist resource managers in making siting decisions for lakebed-altering projects in the Great Lakes. One major application of this system is the siting of offshore wind power generation projects, but its open-ended design also allows it to be used for the siting of other types of projects.
The entire backend analysis functions were initially developed through Python and then adopted to C++ for performance. The front end is ESRI Flex API. The developer of this tool is considering to migrate the whole site to open source solution in the near future.
