Browser based GML Viewer released as Open Source
Senior Software Engineer,
Sydney, Australia, December 21, 2006 - Thales Australia has released an Open Source, Browser based, Geography Markup Language (GML) Viewer as part of the Open Web Services Testbed (OWS4 Testbed).
The GML Viewer can view GML files using recent web browsers without pluggins or a web server. (Firefox 1.5+ or Internet Explorer 6).
It addresses data distributors' need for a simple, self-contained map and data viewer for distribution with GML datasets.
GML2, GML3 and Web Map Server (WMS) layers are supported. The layers are described using the Open Web Services Context (OWSContext) specification (currently in draft) and layer colors are described using a subset of the Style Layer Descriptor (SLD) specification.
The Viewer easily renders layers with hundreds of features in Internet Explorer, and thousands Firefox. Cameron Shorter, the core developer explains:
"I am surprised how fast our browser renderer is. We use Scalable Vector Graphics (SVG) in Firefox and Vector Markup Language (VML) in Internet explorer."
The GML Viewer is powered by Community Mapbuilder which is now uses OpenLayers for its rendering Engine.
The GML Viewer can be downloaded from: http://sourceforge.net/project/showfiles.php?group_id=35246&package_id=96549&release_id=471138
OGC Members can download the GML Viewer with the larger MSD3 dataset and a ten minute flash presentation at: https://portal.opengeospatial.org/wiki/twiki/bin/view/OWS4/GMLViewer#Latest_Downloads
