The service will generate the specified output, and designate a "clickable" location for you to go get the output file. Be careful, and caution your partners not to get carried away with the specified contour intervals -- remember that contours that met NMAS at 10-feet, will NOT meet any kind of accuracy standard at 4 feet.
-in the "Elevation_Source" field you always input the value "BEST_AVAILABLE".
-specify a name that makes sense to you in the "Optional_Shapefile_Name" field
-other "Option" fields can be used but are not "required" for data output.
