Hello all: I have a batch of over 100 raster tiles in ecw format. Each is 50 - 100 MB in size. When I choose 20 or so files to load they appear (render) very quickly - in a matter of a few seconds or less. If I create a vrt of that same batch of tiles, it takes a long time to first render - upwards of 15 - 30 seconds. Once the vrt is loaded response is excellent (zooming, etc). But that initial delay is a bit annoying. Anything I can do to improve it? (QGIS 1.8, Win 7 64 bit) Many thanks, Micha -- Micha Silver 052-3665918 |
