A Revised Landform Map for Areas Prone to Dust Emission in the Southwestern United States: Shapefile Data for the Mojave and Sonoran Desert Regions

Purpose: This repository contains a landform dataset in shapefile format for the Mojave and Sonoran Desert regions. Technical Documentation: LeGrand, Sandra L., Taylor S. Hodgdon, Matthew F. Bigl, and Brendan A. West. 2025. A Revised Landform Map for Areas Prone to Dust Emission in the Southwestern United States. ERDC TR-25-18. US Army Engineer Research and Development Center. https://dx.doi.org/10.21079/11681/49861. Data are provided in shapefile format and use the following codes: Landform Name Landform Code Aeolian dunes Qed Aeolian sands Qe Alluvial fans Qa Alluvial plains Qap Alluvial wash Qal Badlands Qbl Bedrock/plateau/pediment BPP Broad river valley Qrv Fine-grained lake deposits Ql Open mine/tailings Mi Pluvial lake features Qb Recent volcanic deposits Qv River margins / active agriculture Qrm Urban/developed area Ud Water W Note: The previous release on Zenodo contained an error where polygons for only 1 of the 15 classes were included due to a selection or definition query being active when the file was exported. The current version (Zenodo release v2) reflects the dataset described by the technical report by LeGrand et al. (2025).
