Augmented reality support

#Augmented Reality Support

Description

Augmented reality module of mobile application is one of the target of the project. At the moment there isn't an ARML (Augmented Reality Markup Language) server providing data required data. Instead data are available through the means of "traditional" technologies, such as WFS.

Augmented reality support service provides transformation of WFS-based data to ARML.

Note that the stylesheet isn't a general one transforming any incoming data into ARML. Instead, specific style sheet must be defined for each type of input data to reflect its structure.

Current version of the style sheet is just an example of trivial data containg only an idenfication and a geometry.

Details

The main idea is to convert existing data into ARML. As the data is provided by WFS, in form of an XML document, XSLT is the best technology to perform desired transformation.

Geoserver, used as a primary platform to provide geospatial data, includes required functionality. Its XSLT WFS output format module can be used for this purpose. Generally it enables to define an XSLT style sheet to transform data outputed by WFS into desired form.

If source data is providing by a WFS which doesn't support XSLT post-processing, another Geoserver's functionality can help. There's an extension, called External Web Feature Server. It forwards incoming request to an external server and performs required data transformation supported by Geoserver.
