 == Overview ==
 
-This section brefly describes the problem set, and the proposed solution in general terms.  It should be deliberately short, a couple of sentences or so.
+The purpose of this RFC is to allow !MapGuide to stylize the elevation data, which configured surface style in its layer definition.
 
 == Motivation ==
 
-For elevation data, such as DEM file, which would not be displayed in !MapGuide as it does in Map 3D, because the !MapGuide do not have the stylization mechanism for grid surface data as Map does. So, in this release, we will make !MapGuide has the ability to stylize the elevation layer.
-If publish a elevation layer from Map 3D to !MapGuide, the user would see Figure 1 in MapGuide Studio in the future, not the Figure 2, which is the current status for elevation data in MapGuide.
+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:
+{{{
+<LayerDefinition xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xsi:noNamespaceSchemaLocation="LayerDefinition-1.0.0.xsd" version="1.0.0">
+<GridLayerDefinition>
+  <ResourceId>Library://Publish/Data/Raster_1.FeatureSource</ResourceId> 
+  <FeatureName>rasters:davenport</FeatureName> 
+  <Geometry>Image</Geometry> 
+  <GridScaleRange>
+    <SurfaceStyle>
+      <Band>1</Band> 
+      <DefaultColor>0000FF00</DefaultColor> 
+    </SurfaceStyle>
+    <ColorStyle>
+      <HillShade>
+        <Band>1</Band> 
+        <Azimuth>45</Azimuth> 
+        <Altitude>45</Altitude> 
+      </HillShade>
+      <ColorRule>
+        <LegendLabel>-1.79e+308 to 1.79e+308</LegendLabel> 
+        <Filter>(Height(1) > -1.7976931348623158e+308) AND (Height(1) < 1.7976931348623158e+308)</Filter> 
+        <Color>
+          <ExplicitColor>FF00FF00</ExplicitColor> 
+        </Color>
+      </ColorRule>
+      <ColorRule>
+        <LegendLabel>{DEFAULT}</LegendLabel> 
+        <Color>
+          <ExplicitColor>FF006423</ExplicitColor> 
+          </Color>
+      </ColorRule>
+    </ColorStyle>
+    <RebuildFactor>1</RebuildFactor> 
+  </GridScaleRange>
+</GridLayerDefinition>
+}}}
+
+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. 
+So, in this release, we will make !MapGuide has the ability to stylize the elevation layer. If publish a stylized elevation layer from Map 3D to !MapGuide, the user would see Figure 1 in !MapGuide Studio in the future, not the Figure 2, which is the current status for elevation data in !MapGuide.

 == Proposed Solution ==
 
-This is a more detailed description of the actual changes desired.  The contents of this section will vary based on the target of the RFC, be it a technical change, website change, or process change.  For example, for a technical change, items such as files, XML schema changes, and API chances would be identified.  For a process change, the new process would be laid out in detail.  For a website change, the files affected would be listed.
+The proposed solution contains modifications to: Platformbase and Stylization projects.
+
 
 == Implications ==
 
-This RFC does not describe any GUI modifications. The layer definition xml document was published from Map 3D.
-There are no changes to the existing public API. 
+This RFC does not describe any GUI modifications and does not affect the existed published API.
 
 == Test Plan ==
 
-Publish a Grid Surface data from Map 3D to !MapGuide server, at the end the surface image should display as it was shown in Map 3D.
+After publishing a elevation data from Map 3D to !MapGuide server, the elevation image should display as it was shown in Map 3D.
