Appendix C: Creating MapServer CLASS definitions from ARCGIS legends

The MXDtoWMS tool can help you create the complete MapServer map file including CLASS sections from an ESRI ArcMap . mxd file. There are versions for ArcGIS 8 and ArcGIS 9 supplied in the same download but only the version for ArcGIS 9 is described here.

The tool produces complete map files and allows customization of the produced map files. However, we have not used this functionality and, for the purposes of this cookbook, we are only interested in the generation of the CLASS definitions, the other parts of the map file should be edited according to the instructions elsewhere in these cookbook pages.

This tool is free and open source software released under the LGPL license. It can be obtained from the ESRI support center (, the author would like an email if you use it and like it.
