U.G.L.I. (Updatable, Gridded, Lightweight, Impervious) Population Dataset: dasymetric population mapping based on U.S. Census data and 30-m gridded estimates of impervious surface

DOI

This code repository accompanies a dataset and article published in Scientific Data.

Authors

  • Rachel Swanwick (SESYNC; University of Vermont)
  • Quentin D. Read (SESYNC; USDA Agricultural Research Service)
  • Steven Guinn (UMCES IAN)
  • Matt Williamson (Boise State University)
  • Kelly L. Hondula (SESYNC; Battelle, National Ecological Observatory Network)
  • Andrew Elmore (UMCES; SESYNC)

Contents

The code is in three Markdown notebooks containing a combination of R code and Bash commands:

  • dasypop_methods.md: the code to generate dasymetric population estimates by county
  • validation_figure.md: uses the estimates generated in the previous notebook and compares their performance against other existing estimates using flood and wildfire risk data
  • methods_figure.md: generates a figure illustrating the estimation process

How to run

See the individual notebooks for instructions on how to run the code and download the necessary external data. The code in the dasypop_methods.md notebook should be run first.

Recommended citations

The following citations are recommended for the article published in Scientific Data, the permanent stable copy on Zenodo of the GitHub repository containing the code, and the dataset published on FigShare.
