Open SEPPO Tools — Supporting Geospatial and Remote Sensing Data Processing

openSEPPO provides open-source tools for processing and managing geospatial and SAR remote sensing data, with a focus on NASA NISAR products. The tools are designed to scale readily with the SEPPO software by Earth Big Data.

Tools

Command	Description
`seppo_nisar_rslc_convert`	Subset NISAR L-band RSLC HDF5 files directly from S3/HTTPS; output is compatible with isce3, GAMMA Remote Sensing, and SEPPO for interferometric processing; geographic bbox, pixel, and coordinate subsetting; quicklook generation
`seppo_nisar_gcov_convert`	Convert NISAR GCOV HDF5 to Cloud Optimized GeoTIFF (COG), BigTIFF, or HDF5 subset with optional sigma0 conversion, reprojection, downscaling, and VRT time-series stacking
`seppo_nisar_gcov_convert_S`	S-band variant of `seppo_nisar_gcov_convert` (Beta release)
`seppo_nisar_gslc_convert`	Convert NISAR GSLC HDF5 complex data to COG or HDF5 subset: power, amplitude, magnitude, wrapped phase, or raw complex SLC (`-cslc`); supports subsetting, reprojection, downscaling, and VRT stacking
`seppo_nisar_coherence`	Compute pairwise interferometric coherence from co-registered NISAR GSLC complex SLC files with optional crop, downscale, and reprojection
`seppo_nisar_search`	Search NISAR product URLs via NASA Earthdata CMR
`seppo_earthaccess_credentials`	Manage NASA Earthdata S3 credentials and bearer token

Installation

See the Installation guide for full instructions including conda environment setup, pip install, and NASA Earthdata credential configuration.
