Elevation in meters above sea level for all land grid cells. Data from GTOPO data set, original grid resolution at 30 arc seconds. Minimum and Maximum values provide a total within grid cell range of elevation values from the original high resolution GTOPO data set. These 2 data layers are typically not needed except for some river netoworking routines and if some measure of terrain variability is desired. If in doubt use the Mean Elevation data set. files: GtopoElevationMaximum.ease.asc GtopoElevationMean.ease.asc GtopoElevationMinimum.ease.asc
