CATALYST develops automated workflow for South African National Space Agency

CATALYST, a PCI Geomatics brand, has delivered an automated workflow for the South African National Space Agency’s (SANSA) Earth Observation Department to convert decades of SPOT satellite imagery to CARD4L Analysis Ready Data (ARD). The scalable workflow enables SANSA to prepare its entire SPOT archive for immediate analysis using the Open Data Cube, machine learning, and AI models.

CATALYST’s ARD workflow automatically converts optical satellite imagery into ARD measurements by performing a series of image preprocessing operations. The output product is a geometrically precise image with nbar surface reflectance measurements based on the rigor and specifications of CARD4L.

SANSA is the government agency responsible for South Africa’s space programs and research. The SANSA Earth Observation department collects, processes, archives, and disseminates satellite imagery to support policy and decision making, economic growth, and sustainable development. Imagery in the enormous SANSA SPOT archive is used by multiple government departments for programs related to agriculture, water resource management, and responsible development.
