I have 285 Tiff files that make up the 1:10000 OS map of Norhtern Ireland. I am having problems running QGIS when I try to load all 285 tiff files in for base maps (I think the memory on computer is problem here) My thinking was if I create a geodatabase this will speed up accesssing these base maps. I also have with each tiff file a corresponding AUX , RRD, TFW file. There is a historical DBF file that appears to index each Tiff file with max and min x.y coordinates. I beleive this was used for ARC 3?? Is there any easy way to get this DBF file into a spatial database to allow me to access the Tiff files quicker? I tried pyrimids on the Tiffs but they are not 'pyrimid-able'. I also tried to create a geodatabase using spatialite but becasue the Tiffs are not geo-referenced (this info sits outside the Tiff file on the TFW file) it would not allow me to load them into my DB.
Any assistance would be greatly appreciated
