Initial Setup

You need to ensure that Mapserver is setup to server as a WMS/WFS server. If you are not sure, please visit WMS Server HowTo and WFS Server HowTo.

The mapfiles themselves need to be setup manually per Mapserver setup - ARK will not write these for you unfortunately, so its worth undertaking the mapfile setup alongside the official mapfile documentation.

Example Mapfile

ARK uses two different mapfiles, the ark_wfs.map and ark_wms.php. These are found within the ark directory structure in mapserver/mapfiles/.

The files themselves should be reasonably self-explanatory if you have used Mapserver before.

Some things to take care with are the directory locations - as you will need to make sure these match your file structure (especially if you are using *nix).

There are additional comments on the examples below (prefixed with ####).
