    25 The purpose of this RFC is to allow MapGuide users to configure elevation and extrusion parameters in a layer definition, and to use those settings to extrude features vertically in the KML generated for consumption by Google Earth. This provides a highly compelling way to visualize spatial data that contains a vertical component.

    29 MapGuide currently supports 2D representation of spatial data. However, many spatial data sets contain height information for the features they contain, giving the potential for 2.5D representation. This RFC describes how the MapGuide Layer Definition schema can be extended to specify expressions to be used to calculate a base elevation and extrusion size. Support for 2.5D would initially be implemented by the KML service, allowing visualization of solid objects in Google Earth. An example of the potential output is shown below:
