Hi Steve, what you are describing here is exactly what WMS (Web Map Service) offers you.
Geoserver is based on Geotools and supports WMS. Each image sent to the client is composed of different layers. Take a short look to a WMS tutorial. A WMS request describes the pixel dimensions, the world coordinates and a set of layers which you want to see on your result image. First layer could be satellite image, second the roads, afterwards towns, afterwards railways.... Geoserver will deliver an image drawn in the specified order (satellite images first). Addionally, you can create SLD (Styled Layer Descriptions) and tell how to render your layers. (e.g roads in red color, railways in black color) The whole thing is a "standard" procedure :) swebb99 writes: > >> You can display vector data drawn on the map, the client gets an image >> composed of raster data and vector data. > > Hi Christian, > > One further question, I take it the server could be configured to import > vector data for say a road network but then at the client request return > area's of this data in say gif tiles where the background is transparent.
