Worked on enhancing geospatial data interoperability within the OSGeo/gdal repository by extending PCI datum support in C++. Focused on addressing customer data gaps, the developer added GDA2020 and GDA94 to the PCI datums list in ogr_srs_pci.cpp, ensuring broader geographic datum coverage for GIS pipelines. The implementation aligned with existing PCI data flow and adhered to established release practices, maintaining clear commit messaging for traceability. Leveraging expertise in C++ development and geospatial data handling, the work improved the repository’s ability to process diverse geographic datasets, directly supporting customer requirements for accurate and comprehensive geospatial data representation in GIS applications.
