What will I learn?
This GML course teaches you how to create neat XML schemas, represent real-world features, and produce valid GML documents that work well with current GIS tools. You will learn about choosing coordinate reference systems, reprojecting data, and encoding features like wells, zones, and units, along with validation, metadata, interoperability, and quality assurance to make your datasets reusable, well-documented, and simple to fit into existing spatial workflows.
