MiEJScreen version 1.5 user guide

Introduction

At the Michigan Department of Environment, Great Lakes, and Energy (EGLE), Geographic Information Systems (GIS) play a vital role in everything from monitoring air quality to managing water resources. Our interactive web maps make complex environmental data easy to explore and understand.

The 1.5 version of MiEJScreen provides greater functionality and is now more reflective of the functionality used in EGLE’s other mapping tools while maintaining the content incorporated in version 1.0 of the tool.

MiEJScreen is an interactive environmental justice mapping tool, developed by the Office of the Environmental Justice Public Advocate in cooperation with the Interagency Environmental Justice Response Team Research and Data Workgroup. Originally released in 2022, the tool has been moved to a new and improved application to enhance accessibility and functionality. The 1.5 version of the tool retains the original content developed in response to the dedicated advocacy of community members and the 2018 recommendations from the Michigan Environmental Justice Workgroup. Best practices for EJ screening tools around the nation were used to create the resource.

EGLE’s Web Map How-To Guide

EGLE’s Web Map How-To Guide provides step-by-step instructions to help you effectively use EGLE’s web maps on desktop devices. The added details presented here support MiEJScreen users with additional information for use of the tool.

If you are on a mobile device, these maps may look and behave differently.

In addition to this guide, the MiEJScreen page on the Office of the Environmental Justice Public Advocate website and MiEJScreen Technical Report provide greater details on the data and methods behind the tool.

You can find more of EGLE’s mapping tools and data at Michigan.gov/GreenMaps. Designed for clarity and ease of use, our web maps follow a consistent format, ensuring a seamless experience for users navigating spatial data. 

About EGLE’s MiEJScreen web application

MiEJScreen is an environmental justice mapping and screening tool that provides a state-wide consistent dataset and approach that combines environmental, health, and demographic indicators in maps and reports. This can provide detailed information on the challenges communities face and the extent to which they may be candidates for further review, including additional consideration, analysis, or outreach. Percentile scores for MiEJScreen indicators allow for comparisons across census tracts but are not absolute values.

The screening tool provides tables and maps of data by Census tract. Users can view color coded maps and generate a standardized report for a selected area1. Users should keep in mind that screening tools have substantial uncertainty in their demographic and environmental data, particularly when looking at small geographic areas, such as Census tracts. Also, in many cases, data on the full range of environmental impacts and demographic factors in any given location will not be available directly through this tool. This tool’s initial results should be supplemented with additional information and local knowledge2.

Application overview
