Process PeruSat-1 primary scenes into calibrated, orthorectified and pansharpened images.
This package allows you to process PeruSat-1 primary scenes. You can perform the following processing steps:
- Radiometric calibration (top-of-atmosphere)
- Orthorectification
- Pansharpening
It depends on Orfeo Toolbox and some Python packages:
- rasterio
- xmltodict
`perusat_calibrate`: Calibrates image to top-of-atmosphere (ToA).
`perusat_orthorectify`: Adds projection and RPC tags to an image from its metadata files, and then orthorectifies it using the RPC data and a DEM image. If no DEM is provided, a DEM from SRTM is used (1-arc second / 30m aprox GSD).
`perusat_pansharpen`: Bundles a pancromatic (P) and multispectral (MS) image to form a pansharpened image.
`perusat_process`: Given a path to a PeruSat-1 product, it peforms all required steps to form a single calibrated, orthorectified and pansharpened image. Final output can be a virtual raster or a tiff file.
