Installation

See SKILL.md for detailed installation instructions.

Core Python Stack

conda install -c conda-forge gdal rasterio fiona shapely pyproj geopandas

Remote Sensing

conda install -c conda-forge rsgislib   # conda-forge only, not on PyPI
uv pip install torchgeo earthengine-api

Quick Examples

Calculate NDVI from Sentinel-2

import rasterio
import numpy as np

with rasterio.open('sentinel2.tif') as src:
    red = src.read(4)
    nir = src.read(8)
    ndvi = (nir - red) / (nir + red + 1e-8)

Spatial Analysis with GeoPandas

import geopandas as gpd

zones = gpd.read_file('zones.geojson')
points = gpd.read_file('points.geojson')
joined = gpd.sjoin(points, zones, predicate='within')
