I have a data set that is several terabytes in size that I'd like to serve.<br><br>As just a trial, I want to start with a single raster layer. Is there an example of a MapServer setup that I can look at that only serves raster images in the form of individual tiles? The raster examples I have seen use a single image that MS apparently slices up on demand, but no such single image for my data exists (it's far too big).<br><br>What is the recommended approach? I could write a script that can generate the images on demand from the raw data - can these be passed to mapserv? I can also pre-generate tiles of the whole data set. If I want to implement a zoom, presumably I'd generate multiple sets of these at different scales? Would each zoom level be a new layer?<br><br>I'm sure I'll have lots more questions, but this should start me on the right path!<br><br>Cheers,<br>Demitri<br>_______________________________________________<br>mapserver-users mailing list<br>mapserver-users@lists.osgeo.org<br>http://lists.osgeo.org/mailman/listinfo/mapserver-users<br></body></html>
