I am very new to OpenLayers and mapping. I'm trying to display some KML data on a map using a KML layer over a Google map base layer, but have been having problems in getting the points to display accurately in Firefox. I just wondered what other layer types I could use to display information graphically - I had a look at the WMS layer documentation, and have a little understanding of this but I need clarification on a few things: 1. Is WMS like a map web service? 2. If I have a WMS layer on top of a Google Map layer, is it fairly straightforward to get the 2 maps to 'line up' ? 3. How does a CGI WMS request work? What format can the map data be in, and what is the 'wms.cgi' script required to do to process this data in order to return a graphical representation of it? 4. WMS hosting - is it fairly straightforward to configure an existing IIS webserver to handle WMS requests? Many thanks in advance! Clare
