# GeoMaster Comprehensive geospatial science skill covering GIS, remote sensing, spatial analysis, and ML for Earth observation across 70+ topics with 500+ code examples in 8 programming languages. ## Installation ```bash # Core Python stack (conda recommended) conda install -c conda-forge gdal rasterio fiona shapely pyproj geopandas # Remote sensing & ML uv pip install rsgislib torchgeo earthengine-api uv pip install scikit-learn xgboost torch-geometric # Network & visualization uv pip install osmnx networkx folium keplergl uv pip install cartopy contextily mapclassify # Big data & cloud uv pip install xarray rioxarray dask-geopandas uv pip install pystac-client planetary-computer # Point clouds uv pip install laspy pylas open3d pdal # Databases conda install -c conda-forge postgis spatialite ``` ## Quick Start ### NDVI from Sentinel-2 ```python import rasterio import numpy as np with rasterio.open('sentinel2.tif') as src: red = src.read(4).astype(float) # B04 nir = src.read(8).astype(float) # B08 ndvi = (nir - red) / (nir + red + 1e-8) ndvi = np.nan_to_num(ndvi, nan=0) profile = src.profile profile.update(count=1, dtype=rasterio.float32) with rasterio.open('ndvi.tif', 'w', **profile) as dst: dst.write(ndvi.astype(rasterio.float32), 1) ``` ### Spatial Analysis with GeoPandas ```python import geopandas as gpd # Load and ensure same CRS zones = gpd.read_file('zones.geojson') points = gpd.read_file('points.geojson') if z...
