In the course GML Foundations participants learn to deal with the OpenGIS Geography Markup Language Encoding Standard (GML).
GML is an XML vocabulary to express geographic properties. GML is not only a modeling language for geographic systems, but also an open standard for geographic transactions over the Internet.
Like all XML vocabularies the GML grammar has two parts: an XML Schema that describes the document structure and instance documents that describe the actual data.
In the course different variants of GML syntax are discussed such as INSPIRE GML and AIXM5 GML.
The course starts with an overview of the basic concepts of XML such as the XML document structure, the XML syntax rules and the difference between well formed and valid documents. The role of XML Namespaces is also discussed here.
Subsequently the XML Schema standard is discussed, which defines the naming, sequence and data types of XML instance documents based on a schema. The different styles of XML Schema construction and the definition of simple and complex user defined data types are discussed.
Then attention is paid to the GML data model with the Features, Geometry, Topology and Temporal Schemas. And also the GML domain vocabulary with Spatial Values, Object Property Rules, Associations and the role of Attributes is discussed.
An explanation of GML components such as Points and Curves, Surfaces and Solids, Nodes, Edges, Faces and Curve Segments are also part of the course program. This also includes Surface Patches, Interpolated Curves, Coverages and Surface Interpolation.
Finally the GML Coordinate Systems with CRS Dictionary Entries, Units of Measure and Quantity Types and GML Modeling with Schema Repositories, Substitution Groups and Schema Modularization are discussed.
The course GML Foundations course is intended for analysts and developers who want to learn the basics of GML and apply GML in geographic information systems.
Basic knowledge XML is required to participate in this course.
The theory is discussed on the basis of presentation slides. The theory is explained further by means of practical demos. After discussing a module, there is the possibility to practice. Course times are from 9.30 to 16.30.
Participants receive an official certificate GML Foundations after successful completion of the course.
