Adriaan Keurhorst developed an Urban Heat Island (UHI) analysis feature for the ESA-APEx/apex_algorithms repository, focusing on summer-season assessments using Landsat data. He implemented a User-Defined Process (UDP) in Python to calculate temperature differences between urban and rural areas, enabling repeatable and scalable UHI workflows. The technical approach included updating output paths to relative references, improving portability for UHI_JJA Torino results. His work leveraged skills in algorithm development, data analysis, and geospatial processing with openEO, laying a foundation for future feature expansion. No bug fixes were reported, reflecting a focus on new feature delivery and workflow design.
