Enumerates Sentinel-1 A/B Interferograms
Project description
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.
from s1_enumerator import distill_all_pairs, enumerate_ifgs
# Over Los Padres National Forest, CA
point = Point(-120.0048, 34.8923)
aoi = point.buffer(1)
# Get all data from ASF Search
ifg_pairs_tiles = enumerate_ifgs(aoi,
min_reference_date=datetime.datetime(2021, 7, 9),
enumeration_type='tile',
min_days_backward = 364,
num_neighbors_ref=3,
num_neighbors_sec=1,
temporal_window_days=60,
min_ref_tile_overlap_perc=.2,
min_tile_aoi_overlap_km2=1e3,
minimum_path_intersection_km2=1e3,
minimum_ifg_area_km2=3e4,
entire_s1_catalog=False
)
# Distill for Generating IFGs
df_pairs = distill_all_pairs(ifg_pairs_tiles)
