Hi Brent,<br> <br> thank you very much for your answer, it was very helpful. One question:<br> the NVIZ component, could I use that isolated from the rest of GRASS GIS, i.e.<br> without all the other components to keep my system small and fast?<br> Yet another question: Do you know whether there is a fast, thin client for<br> accessing Web Map Services (WMS) which does caching when getting raster<br> data (so that e.g. when I shift the current field of view, the client not always has to<br> reload new data from the server)? Whether 3D or only 2D plays no role, optional<br> 3D would be nice, however.<br> And one last question: When I get realtime data from a server, e.g. GPS data of<br> some object, is it possible to overlay that data over a map with a WMS<br> without storing the data in a database (which, I think would slow down the<br> realtime process because of the hard disk access)? Speed is an issue in my<br> scenario.<br> <br> You would greatly help me since I am a
newbie in this area, so be thanked in<br> advance for any help.<br> <br> Best regards, Peter.<p>
