<div style='text-align:Left;'><p><span>The Annual Sentinel-1 RTC Mosaic Image Service (2015–2023) is derived from Copernicus Sentinel-1 synthetic aperture radar (SAR) data. The mosaics are generated using Radiometrically Terrain Corrected (RTC) backscatter products produced through the ASF on-demand processing pipeline. Each annual mosaic was assembled from scenes acquired in the first week of August, when available, to provide consistency in seasonal conditions.</span></p><p><span>The mosaics are structured using the ArcGIS mosaic dataset framework and published as a time-aware image service on ArcGIS Server. Users can visualize backscatter changes over time via the time slider and perform on-the-fly calculations of spectral indices and band ratio composites. Due to the failure of Sentinel-1B in December 2021, mosaics for 2022 and 2023 have missing sections. More details on the RTC product generation can be found at the ASF RTC Guide: https://hyp3-docs.asf.alaska.edu/guides/rtc_product_guide/</span></p></div> |
