This mapping tool uses MIMU Place Codes to enable the preparation of simple 'heat maps' to compare data from Excel spreadsheets across states/regions and townships. It can compare and contrast different indicators from larger, national datasets such as the MIMU Baseline Dataset, and can also be used with agencies' own information from different areas.

The new Excel Mapping Tool (version 2.0) introduces Leaflet JavaScript library, instead of using Excel built-in features to make heat maps. To view the result, a browser is needed (for example, Firefox or Google Chrome).
