+Currently, !MapGuide do not have the stylization mechanism for grid surface data. So, in this release, we will make !MapGuide has the ability to stylize the elevation layer. The user would see the stylized elevation data, like Figure 1 in !MapGuide in the future, not the Figure 2, which is the current status for elevation data in !MapGuide.

 == Proposed Solution ==
 
-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.

 == Test Plan ==
 
-After publishing a elevation data from Map 3D to !MapGuide server, the elevation image should display as it was shown in Map 3D.
+Add an elevation layer to !MapGuide, the elevation layer should display with grid surface, like Figure1.
