CN Grind Created from Soil and Landuse

This data collection consists of landuse and soil rasters andcn grind for Cyber Training Class week 12 works. Initial codes were provided by the instructor Dr. Venkatesh Merwade.

The landuse raster file is a reclassified National Land Cover Dataset (NLCD) raster. Original landuse raster file contains integer values 11-95 to represent different types of land cover (e.g. 11 represents open water). It was reclassified based on a .csv file that contains original value ranges and new values.

The soil raster was created from Gridded Soil Survey Geographic (gSSURGO) database file. It contains multiple features that represent different soil properties. One field named \"HSG_Index\" gives information about hydrologic soil group (1-HSG A, 2-HSG B, 3-HSG C, 4-HSG D).

The CN grind is generated based on the landuse raster file, the soil raster file, and a curve number lookup table. The curve number lookup table contains combinations of landuse value and soil HSG_Index value combinations and respective CN value.

All calculations were completed though python codes using Jupyter notebook with Anaconda 5.1 on MyGeoHub.
