Full Form of GML
What is GML?
Geography Markup Language (GML) is an XML-based encoding standard designed for representing geographic information, including features, geometries, and coordinate reference systems. Developed by the Open Geospatial Consortium (OGC), GML enables the exchange of spatial data across diverse systems and platforms. In India, GML is widely adopted by government agencies such as the Survey of India, the National Informatics Centre (NIC), and various state GIS departments for sharing geospatial data related to land records, urban planning, disaster management, and infrastructure projects. It is also used in the National Geospatial Policy and the Indian Earth Observation System. GML ensures interoperability among different GIS software and web services, facilitating seamless integration of data from multiple sources. The format is particularly important for implementing Web Feature Services (WFS) and cataloguing spatial datasets. For students and professionals preparing for exams like GATE (Geomatics), UGC NET Geography, or state PSCs, understanding GML is essential as it appears in topics on spatial data standards and remote sensing. Its structured nature, support for complex geometries, and ability to encode temporal and topological relationships make it a cornerstone of modern geospatial technology in India and globally.

How is GML used in India?
GML is used by Indian government agencies like the Survey of India and NIC to exchange land records, disaster mapping, and urban planning data in a standardised format.
What is the difference between GML and KML?
GML is a comprehensive OGC standard for complex geographic data, while KML is a simpler format originally for Google Earth, often used for displaying points of interest.
