This really has nothing to do with GDAL (or any WMS source) per se -- it depends on how yo uwant o use the results. Tiles are used for the google-maps-style (also used for many open source web map systems: open layers, leaflet, etc) "slippy maps". In general, tiles work really well if you have a map that covers a wide area that you want people to be able to pan around on and/or have maps that are slow to render, and don't change much. But in short: if you want an image, you don't want tiles. If you are using a tile-based map display system, you probably do want tiles. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception [email protected] _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
