I've read that some providers communicate in XML, do you know of any examples on the web (access to code xml document trees etc.)?
How do GIS software providers provide the map to the client and in what format is it?
What information does the client need to send in order for the provider to process a request for a map?
What information does the provider need to send back to the client in order to enable them to plot objects on the map they have recieved?
Will the client need special software in order to plot real co-ordinates on the map (for example if they wanted to plot the location of a pub using real geographical co-ordinates)?
If I were to use the PHP's longitude and latitude co-orrdinate functions to plot the objects on the map at the client end, would I be able to do this with a street level map? If it can, then how?
