Hi Jürgen
One of the options may be to merge together files.
I have an image, 32000x16000 tiled RGB tiff, 1.7GB in size which is
served like a lightning by an old computer, not even designed to be a
server, with 1.5 GB of RAM.
Software configuration - same as yours.
By merging rasters you can reduce the number of files almost 60 times,
which means that you will have 15-20 files, roughly.
Of course, you know better, if your project allows this, but in general,
MGOS seems to handle easier a small number of big files, rather than a
big number of small files.
Best regards : Stefan Dalakov

Hi,
I have a problem with a rasterlayer (not tiled).
It is a layer using about 1000 TIFF-Files (RGB, 3000x3000 pixel, scale 1:1000).
The visibility of the layer is 1:100 to 1:5000.
If I load the map (sacle 1:2000) I get the error: Out of memory. bad allocation.
If I reduce the number of tiff-files in the folder (500) I get no error but the
map is loading very, very slow.
If I change the format from tiff to jpg or ecw (all 1000 files) I get no error
but the map is also very slow.
I get the same error with Autodesk Raster FDO and OSGEO Gdal
MGOS 2.02 or MGOS 2.1.0 Beta
W2003 Server SP2
IIS 6.0
AjaxViewer (JSP)
is there any solution for this problem?
Jürgen
