Global Hydrologic Soil Data for Runoff Modeling

Posted by Remote Sensing Biodiversity | Mar 29, 2018 | data |

A hydrological soil data set for runoff modeling is available online by EartData. From their webpage: “This dataset – HYSOGs250m – represents a globally consistent, gridded dataset of hydrologic soil groups (HSGs) with a geographical resolution of 1/480 decimal degrees, corresponding to a projected resolution of approximately 250-m. These data were developed to support USDA-based curve-number runoff modeling at regional and continental scales. Classification of HSGs was derived from soil texture classes and depth to bedrock provided by the Food and Agriculture Organization soilGrids250m system.”
