PROFILE
Luís De Sousa
Luis de Sousa enhanced the opengeospatial/ontology-crs repository by developing and refining geospatial ontology data models, focusing on coordinate reference systems and metadata enrichment. He applied skills in CSV manipulation, ontology engineering, and SHACL to standardize labels, definitions, and data structures, improving clarity and interoperability for downstream geospatial applications. His work included expanding support for compound CRSs, DGGS projections, and PROJJSON compatibility, as well as implementing robust metadata management and validation constraints. By consolidating data quality improvements and addressing structural gaps, Luis delivered well-documented, maintainable solutions that strengthened data integrity and streamlined integration with geospatial tools and standards.
