Dataset of Roughness Index (RI), Rg and DEM data from the terraced area of the Fish Creek–Vallecito Basin (San Andreas Fault System, southern California)

This dataset contains the geospatial data used to calculate the Roughness Index (RI) in the main study area. It includes:– A shapefile of the main study area roughness (RI).– A 20 × 20 m cell shapefile of the terraced area.– A shapefile of three profiles.– Three Excel files with cell IDs and the values of two normalized equations linked to each cell (Profiles). –One Excel files with cell IDs and the values of Rg of the terraced area (20x20 m cell). – A DEM (Digital Elevation Model) of the terraced area. All files are provided with their associated components (e.g. .shp, .shx, .dbf for shapefiles).The dataset uses the EPSG: 26911 coordinate reference system (UTM Zone 11N). These data support the article “Detecting active cryptic faults from surface roughness in the Fish Creek Vallecito basin, San Andreas fault system, southern California” published in Journal of Geophysical Research: Earth Surface.
