I have a data set that I downloaded from the national elevation data set (NED).  The data is for a river meander reach.  Is there a way that I can convert the raster data to polygons, consistent with the way in which I have symbolized the data in the attached example?  The data is symbolized based on elevation ranges (z values) shown in the dialogue box.

Reclassify comes first since it will result in an integer raster, then convert to polygons.  You can't convert floating point rasters into polygons.

Best,
Eric

You probably need to do a Polygon to Raster:

Followed by a Reclass:

Licensing would require Spatial Analyst or 3D Analyst.
