What is the main purpose of GML?

What is the main purpose of GML?

Overview. Geography Markup Language (GML) is an XML application that provides a specialized vocabulary for working with geographic data. The main purpose of GML is to provide a standard means for representing information about geospatial Features—their properties, interrelationships, and so on.

What opens a GML file?

How to open file with GML extension?

1. Install FME Desktop software.
2. Update FME Desktop to the latest version.
3. Set the default application to open GML files to FME Desktop.
4. Check the GML for errors.

What does GML mean?

The Geography Markup Language (GML) is the XML grammar defined by the Open Geospatial Consortium (OGC) to express geographical features. GML serves as a modeling language for geographic systems as well as an open interchange format for geographic transactions on the Internet.

What does GML file mean?

Geography Markup Language
A GML file format, also known as a Geography Markup Language, is an XML like format that is defined by the Open Geospatial Consortium (OGC). This type of XML is optimized to express geological features. That makes GML an interchange format for geographic transaction on the internet.

What is the Geography Markup Language ( GML )?

The Geography Markup Language (GML) is an XML encoding in compliance with ISO 19118 for the transport and storage of geographic information modelled in accordance with the conceptual modelling framework used in the ISO 19100 series of International Standards and including both the spatial and non-spatial properties of geographic features.

How is GML used as a modeling language?

GML serves as a modeling language for geographic systems as well as an open interchange format for geographic transactions on the Internet. Note that the concept of feature in GML is a very general one and includes not only conventional “vector” or discrete objects, but also coverages (see also GMLJP2) and sensor data.

What are the geometries of a GML document?

GML encodes the GML geometries, or geometric characteristics, of geographic objects as elements within GML documents according to the “vector” model. The geometries of those objects may describe, for example, roads, rivers, and bridges. The key GML geometry object types in GML 1.0 and GML 2.0, are the following:

What is the definition of feature in GML?

The concept of feature in GML is a very general one and includes not only conventional “vector” or discrete objects, but also coverages and sensor data. The ability to integrate all forms of geographic information is key to the utility of GML.
