I've got a fairly large set of .tif files (A total of 2774 images at roughly 400mgs each). They've all had gdaladdo run (at 2 4 8 16), and then a tile index created. If I attempt to draw the map with mapserver at the full extents, the cgi request times out. I realize this is too much data, but the question is: how do I find out at what point the tile index will break down and overview should be used? Also, if MapServer won't draw the composite image, will shp2image work? This is running on a linux machine with 4 2.8 ghz Pentiums and 4gb RAM...
Chris, Mapserv *should* work if given enough time but for a full overview image processing through 2700 files still takes quite a while. Likewise shp2img should work. The operational solution is to create a low resolution mosaiced layer all in one file and use MINSCALE/MAXSCALE on the layers to switch between the tileindex layer and the overview layer at appropriate scales.
