DePSI: Delft PS-InSAR processing package
This repository holds a beta version of DePSI. The code is still under development and should still be properly tested and documented. Still, you are invited to have a look at the current code base and send us your suggestions.
DePSI (van Leijen, 2014) is an open source Python software package for Persistent Scatterer Interferometric SAR (PS-InSAR) processing. It provides a comprehensive suite of functions to identify Persistent Scatterer (PS) points from a time series of interferometric SAR data, and estimate their deformation time series based on customizable assumptions, such as a predefined deformation model.
DePSI was originally implemented in MATLAB in 2014. The Python implementation of DePSI is motivated by acconmondating the classic DePSI algorithm into a modern software framework, enabling easier maintenance and contribution from the InSAR community. The Python version also enables the support of parallel computing and handling large datasets by leveraging Dask and Xarray libraries.
Installation
You can install DePSI from the Python Package Index (PyPI) using pip:
Please refer to the Installation Guide for more details.
