Abstract
This resource serves as a template for creating a curve number grid raster file which could be used to create corresponding maps or for further utilization, soil data and reclassified land-use raster files are created along the process, user has to provided or connect to a set of shape-files including boundary of watershed, soil data and land-use containing this watershed, land-use reclassification and curve number look up table. Script contained in this resource mainly uses PyQGIS through Jupyter Notebook for majority of the processing with a touch of Pandas for data manipulation. Detailed description of procedure are commented in the script.

Description: This folder contains a script/template used to create the curve number (CN) grid raster file, final CN grid raster, soil data and reclassified land-use raster generated along the way, and three example maps created from the raster files. ######################################## Folder content description: Raster_files - final output raster of curve number grid and intermediate output of soil data and landuse reclassification. Maps - example png files of maps created from above raster files with ArcMap. ######################################## Notes for script 1. The initialization of the PyQGIS should be run only once each session or else it would crash. 2. Boundary, soil data shapefile and land-use raster file in the example are provided by connection to a public folder containing them, user can upload and connect to said files, additional CN look up and landuse reclassification table are also required. 3. A coordinate reference system check is needed to ensure all shapefile and raster file are in the same reference system. These are some important prerequisitions and things to look out for, More detailed guide on how to run the script is included in the comments.
