S1-Enumerator
Uses asf-search to enumerate Sentinel-1 A/B pairs for interferograms.
Also provides functions to check if a S1-GUNW exists in the ASF DAAC.
Install
pip install s1-enumerator
Requires asf_search, geopandas, rasterio, requests, and tqdm. See the environment.yml.
Usage
See notebooks for examples.
