Thanks for your continued support Michael Branscomb
It would seem that 'animation' presumes you have all the images before the animation begins...
In actual fact, I have a flood modelling system, for which I'd like to show the outputs, and because of this I won't have the rasters until they are produced by the model.
Thanks for clarifying the localServer a bit more. Would the local server be able to load the the ASCII files into data and pass that to the map, which would be quicker and more effecient than converting them with GDAL.
I'm still trying to get the colours right in another post, but again because this will be model output, the size and number of rasters could vary. Although the number of rasters, would mainly depend on what the system can push through in a given time, thus my questions of the efficiency of loading/converting/passing data etc.
Cheers muchly
