-Map 3D can publish stylized elevation layer, such as DEM and GeoTIFF file to !MapGuide. The layer definition for an elevation data in Map 3D would like below, with surface style:

+Map 3D can publish stylized elevation layer, such as DEM and GeoTIFF file to !MapGuide. 
 
 While, !MapGuide cannot display this elevation data published from Map 3D with surface style, because the !MapGuide do not have the stylization mechanism for grid surface data.

 == Proposed Solution ==
 
-The proposed solution contains modifications to: Platformbase and Stylization projects.
-
+Modify Stylization project to support the stylization of the elevation data, with surface style. New classes will be introduced to handle those style information, such as color, band, surface, hillshade and etc.
