QUICK START
from gexus import GeoTIFFTransform, RasterBandMathTransform
# Process satellite imagery for vegetation analysis
ndvi_pipeline = (
pipeline
| 'Read Satellite' >> GeoTIFFTransform('landsat/*.tif')
| 'Calculate NDVI' >> RasterBandMathTransform("(B4 - B3) / (B4 + B3)")
)WHAT'S NEXT
GeXus now provides the complete foundation for big geospatial data processing. This release positions GeXus as the go-to solution for organizations processing satellite imagery, environmental data, and integrated geospatial workflows at scale.
Installation: pip install -r requirements/base.txt
Documentation: See docs/geotiff_reader.md
