Digitizing in Python

Purpose

The purpose of this tutorial is to automate the digitization of land cover features such as vegetation, waterbodies, and roads, using Sentinel-2 satellite imagery and Python-based geospatial tools.

Objective

Use Google Earth Engine (GEE) to acquire the satellite images for processing in python. Compute NDVI (vegetation), NDWI (water), NDBI (roads) indices. Export rasters to your Google Drive. Convert rasters to vectors. Visualize and colourize digitized features.

Software

Google Earth Engine Google Colab or any other Python language system or notebooks. Python libraries: <earthengine-api, geemap, rasterio, geopandas, shapely, matplotlib>
