New algorithm improves SAR-optical corpus creation for Earth Observation

Researchers have developed a new algorithm called Deficit-Driven Stratified Acquisition (DDSA) to address the challenges of building co-registered SAR-optical corpora for self-supervised Earth Observation. Unlike opportunistic data collection, DDSA treats corpus construction as a constrained maximum-coverage problem, ensuring temporal pairing and quality control through a multi-stage process and a human-in-the-loop repair stage. This method successfully populates all strata from the initial budget and recovers a significant portion of pairs through its repair loop, resulting in the release of the STRATA-S12 corpus, which is confirmed to be suitable for self-supervised pre-training.

    Deficit-Driven Stratified Acquisition for Building STRATA-S12: An Open SAR-Optical Corpus for Self-Supervised Learning

    Building a co-registered SAR-optical corpus for self-supervised Earth Observation is above all an acquisition problem, yet the main multi-modal datasets are collected opportunistically, with no per-stratum quota control and no mechanism against the geographic dropout that non-uni…
