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.

All our courses are classroom courses in which the students are guided through the material on the basis of an experienced trainer with in-depth material knowledge. Theory is always interspersed with exercises.
We also do custom classes and then adjust the course content to your wishes. On request we will also discuss your practical cases.
The course times are from 9.30 to 16.30. But we are flexible in this. Sometimes people have to bring children to the daycare and other times are more convenient for them. In good consultation we can then agree on different course times.
We take care of the computers on which the course can be held. The software required for the course has already been installed on these computers. You do not have to bring a laptop to participate in the course. If you prefer to work on your own laptop, you can take it with you if you wish. The required software is then installed at the start of the course.
Our courses are generally given with Open Source software such as Eclipse, IntelliJ, Tomcat, Pycharm, Anaconda and Netbeans. You will receive the digital course material to take home after the course.
The course includes lunch that we use in a restaurant within walking distance of the course room.
The courses are planned at various places in the country. A course takes place at a location if at least 3 people register for that location. If there are registrations for different locations, the course will take place at our main location, Houten which is just below Utrecht. A course at our main location also takes place with 2 registrations and regularly with 1 registration. And we also do courses at the customer’s location if they appreciate that.
At the end of each course, participants are requested to evaluate the course in terms of course content, course material, trainer and location. The evaluation form can be found at https://www.klantenvertellen.nl/reviews/1039545/spiraltrain?lang=en. The evaluations of previous participants and previous courses can also be found there.
