i am wondering whether there's Python open-source GIS lib which has APIs to support call WMS/WFS from another GIS server (e.g., GeoServer) and then save the response data(WMS Basemap and WFS layer) as pictures.
thanks for any inputs!
what I am trying to do is a Map Printing service, by using OpenLayers as the front-end and Django as the server; Client user set the extent and layers and then send the print request (which refers to the parameters, i.e., map extent, names of layers) to server, then server takes over this request and call WMS/WFS again by using request parameters, save the response as PDF, export this PDF link to client.
The difficult part is that how the server call WMS/WFS and combine/overlay these responses together (i.e., put these map/layers together, since WMS is usually the base map, WFS points to the feature layers), finally save this combined object as Image.
in current answers, urllib seems a good one, but i am not sure how to combine these responses (WMS, WFSs) together; OWSLib also seems another good option, but it indicates it's a client programming tool, I am a little confused that whether it's appropriate for my use...
any other further inputs???
