GML (Geography Markup Language)

GML (Geography Markup Language) is an XML-based format used to represent and share geographic information digitally. Think of it as a universal language for maps and spatial data, allowing different systems to understand, exchange, and interpret geographic features like roads, rivers, or boundaries consistently. It enables detailed geographic data to be stored, transferred, and integrated across various applications and platforms, supporting tasks such as GIS (Geographic Information Systems), mapping, and spatial analysis. In essence, GML helps make geographic information interoperable, precise, and accessible in a structured, machine-readable format.
