LADST Introduction

Welcome to the main page for the Lakebed Alteration Decision Support Tool. Here you can find an overview of our project and links to the new online, interactive tools.


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. Our project brings an unprecedented level of interactivity to bear upon the problems of marine spatial planning. Users of the system can create their own suitability maps in an online tool, based upon suitability criteria of their own choosing. In this way, the different priorities or values of different Great Lakes stakeholders, as well as the different suitability requirements of different types of development projects, can be represented by a single data analysis system.

Here are our new, online decision support tools:

Click here to use the State of Michigan Decision Support Tool
This version has more data sets, but a narrow geographic extent: only the waters of the State of Michigan.

Click here to use the U.S. Great-Lakes Decision Support Tool
This version covers all of the U.S. waters of the Great Lakes, but only contains data sets that apply to that entire area.

Click here to use the Great-Lakes-wide Decision Support Tool
This version covers all waters of the Great Lakes (both U.S. waters and Canadian waters), but only contains data sets that apply to that entire area.

Status of the Decision Support Tools

We would appreciate feedback about the usability of our system; feel free to e-mail our project directly, at

Please note that users who have a license to the ArcGIS software package can already use the earlier ArcGIS-Desktop-based versions of our decision support tools. Click here for more information.


Funding for this project was provided, in part, by the U.S. Department of Commerce, National Oceanic and Atmospheric Administration (NOAA), via Michigan's Coastal Management Program (part of Michigan's Department of Environmental Quality), and by the U.S. Department of Energy. Personnel for the project are located at the NOAA Great Lakes Environmental Research Laboratory, and the Institute for Fisheries Research, which is a cooperative unit of the University of Michigan and Michigan's Department of Natural Resources. This project builds upon the work of the Great Lakes GIS (GLGIS) project, which initially assembled and organized most of the data sets used by the LADST, and also the ongoing Great Lakes Aquatic Habitat Framework (GLAHF) project, which has provided several of the newest data sets used by the LADST.
