Copernicus Senwise RoseL-like imagery, Vidauban, FR 2, 2024

FAIR Overall Score

Abstract

The input RoseL-like imagery dataset is a copy of SAOCOM-1B SAR Stripmap dual pol (VH-VV) data collection downloaded from saocom.asi.it. Data are in the Single Look Complex (SLC - Level-1A) format suitable for InSAR/PolSAR processing. Coordinates are [5.95, 43.46], [6.90, 42.88]. Data cover the Vidauban area, South of France, where a wildfire happened in Summer 2024. Data are acquired in ascending (ASC) orbit and are given here in the SAR acquisition geometry (slant range, azimuth coordinates). Both extent and numbers of rows and columns vary a bit from one image to the other: values given here correspond to the 1st image of the collection. One geoprojected (.tif) image out of the collection is provided for information only, for allowing to locate the relevant area.
