NLCD-Evaluations-Builder

A repository to build evaluation maps using the National Land Cover Database for the US

Geodesignhub NLCD Evaluation Maps Builder

This program uses CORINE landcover data from Multi Resolution Land Characteristics Consortium (MLRC) to develop Evaluation maps for Geodesignhub. It uses simple rules to parse the existing data and build evaluation maps that can be used directly on Geodesignhub. NLCD data is available only for mainland United States so this tool can be used to make evaluation maps only for sites in the US.

Making evaluation maps is the most time consuming part of a Geodesign study, using this script it can be automated. The following evaluation maps are generated:

Installation

Use the requirements.txt file to install libraries that are required for the program

pip install -r requirements.txt

3-Step process

1. Download raw data

  1. Go to Multi Resolution Land Characteristics Consortium (MLRC) to order and download the NCLD raster data and clip it to your area of interest.
  2. Convert the clipped area to Vector by using the Polygonize command for e.g. in QGIS
  3. Put this file in the working folder
  4. Update the config.py file to show

2. Update config.py

  1. Set the boundary parameter to set the bounding box co-ordinates in (southwest_lng,southwest_lat,northeast_lng,northeast_lat) format.

3. Upload Evaluations

  1. Run the NLCD-evaluations-generator.py script and check the output folder for the Evaluation GeoJSON that can be uploaded to Geodesignhub
