Colorado EnviroScreen

Colorado EnviroScreen is a data processing code base with a public facing shiny application that highlights the spatial variability of specific Environmental Health and Environmental Justice challenges throughout Colorado. This document is intended to guide users in the generation of the Colorado EnviroScreen dataset that supports functions as the input to the shiny applications.

This content was developed by the Geospatial Centroid at Colorado State University under the direction and support of the Rojos Pulbic Health Lab at CSU, Institute for the Built Environment at CSU, and the Colorado Department of Public Health and Environment.

Vision

The code base for generating the Colorado EnviroScreen score dataset utilizes a hierarchical workflow that matches general scoring presented on the application

• EnviroScreen Score
  • Group Component Scores
    • Component Scores
      • individual Indicator Scores

This allowed for a module approach to the development. The primary motivator for this process was to allow for the quick regeneration of all elements if a single input feature was changed. This was accomplished by writing out intermediates at ever step in the process. All data processing functions have an version and overwrite parameter with give the user the specificity needed to control how much data is regenerated or compiled from the existing intermediate file. In short, the code base is going to included what’s already there unless told otherwise. This keeps it fast and flexible.

As with any codebase, this will require some maintenance and adjustment going forward. We hope that what is provided is a viable starting place for a long-lived and successful project.
