-<h1>Raster Rendering Rule</h1>
+<h1>Raster rendering rule</h1>
<p>Display a raster on a map and apply different rendering rules to that raster.</p>

-<h2>Use case</h1>
+<h2>Use case</h2>
-<p>A single raster image can be rendered in a number of different ways, including representation of slope aspect, hillshade and shaded relief. Applying these different renderers to the same raster allows for a powerful visual analysis of the data. For example, a geologist could interrogate the raster image using all available renderers to map subtle geological features on a landscape not apparent in a regular aerial photograph.</p>
+<p>Raster images whose individual pixels represent elevation values can be rendered in a number of different ways, including representation of slope, aspect, hillshade, and shaded relief. Applying these different rendering rules to the same raster allows for a powerful visual analysis of the data. For example, a geologist could interrogate the raster image to map subtle geological features on a landscape, which may become apparent only through comparing the raster when rendered using several different rules.</p>
<h2>How to use the sample</h2>
<p>This raster image service contains 9 LAS files covering Charlotte, North Carolina's downtown area. The lidar data was collected in 2007. Four Raster Rules are available for selection: None, RFTAspectColor, RFTHillshade, and RFTShadedReliefElevationColorRamp.</p>
+<h2>Additional information</h2>
+
+<p>Image service rasters of any type can have rendering rules applied to them; they need not necessarily be elevation rasters. For a list of raster functions and the syntax for rendering rules, see the ArcGIS REST API documentation: https://developers.arcgis.com/documentation/common-data-types/raster-function-objects.htm.</p>
