- Description:
- This repository includes a file containing polygon data for river channel data for eight study reaches (1, 2A, 2B, 2B short, 3A, 3B, 4A, 4B) across multiple years (1974, 1981, 1995, 2000, 2007 to 2017, and 2018 to 2022), along the Escalante River, Utah, USA. Each channel delineation is uniquely identified by year and reach. Historic imagery was collected from United States Geological Survey and Bureau of Land Management; sourced imagery was accessed through EarthExplorer ( https://earthexplorer.usgs.gov/#close); NAIP imagery from the USDA Geospatial Data Gateway ( https://datagateway.nrcs.usda.gov/GDGHome_DirectDownLoad.aspx); and ESRI imagery from World Imagery Wayback ( https://livingatlas.arcgis.com/wayback/#active=16681&mapCenter=-111.19835%2C37.64870%2C18)
