# Rasterio Satellite GeoTIFF Processing & Windowing

Processes raster data using Rasterio (GDAL): reading multi-band GeoTIFFs, extracting metadata and affine transforms, windowed reads for large rasters, calculating NDVI band indices, and rasterizing vectors.

## When to Invoke
Invoke this skill whenever you need to:
- read geotiff rasterio
- calculate ndvi rasterio
- windowed reading rasterio

## Execution SOP & Rules
1. Open dataset: with rasterio.open('satellite.tif') as src: red = src.read(4); nir = src.read(8).
2. Compute band math: ndvi = (nir.astype(float) - red.astype(float)) / (nir + red).
3. Perform windowed read: src.read(1, window=rasterio.windows.Window(col_off=100, row_off=100, width=500, height=500)).
4. Write output raster updating profile with driver='GTiff', dtype='float32', and compress='deflate'.

## Verification Checklist
- Run local linting, syntax validation, and type-checks before reporting completion.
- Ensure all created or modified files adhere to workspace boundaries and avoid uncommitted secrets.
- Verify tests or build commands exit cleanly with return code 0.
