High-performance software framework for the calculation of satellite-to-satellite data matchups (MMS version 1.2)

Abstract

We present a multisensor matchup system (MMS) that allows systematic detection of satellite-based sensor-to-sensor matchups and the extraction of local subsets of satellite data around matchup locations. The software system implements a generic matchup-detection approach and is currently being used for validation and sensor harmonization purposes. An overview of the flexible and highly configurable software architecture and the target processing environments is given. We discuss improvements implemented with respect to heritage systems, and present some performance comparisons. A detailed description of the intersection algorithm is given, which allows a fast matchup detection in geometry and time.
