Overview

Welcome to the Great Lakes Habitat Explorer! This website includes a data viewer that allows you to view a variety of spatial information related to aquatic habitats in the Great Lakes at user defined extents. The website also includes a habitat suitability explorer with features that allow you to search for habitat areas which meet your criteria, annotate the habitat map, as well as search, export, and print the data. This information page provides a brief overview of the main features.

The Great Lakes Aquatic Habitat Explorer allows users to view and query spatial data layers, search for habitat that meet your criteria, zoom to different locations in the Great Lakes, add annotations to your map, and save and print the map that you created.

To learn more about the process of developing the GLAHF Explorer tool, please see our manuscript Goodspeed et al. (2016).

  • View the symbology for a layer by clicking the plus sign next to the layer name
  • By clicking on the menu icon, users can:
    • Adjust the order the layers are displayed
    • Zoom to a layer
    • Adjust the transparency of the layer
    • View the layer metadata

Habitat Criteria

This function allows the user to select combinations of spatial data with ecologically defined criteria to identify areas of habitat that meet those criteria. The available criteria are organized by headings and the criteria are listed below the data headings. Information about the criteria and how they were defined are available from the small information icon.

To use the function, select options for the layers you would like to include in your investigation. At the bottom, select whether you are interested in areas which match any or all of the criteria, and click “investigate” to see the results. The clear button removes the results from the map.

The tool will allow you to investigate any criteria, regardless of whether the resulting area is actually suitable habitat for any plant or animal species. Scientifically validated habitat maps can be viewed in the layers tool.
