SPAM-LOW: [mapguide-users] Raster files

[Traian Stanev]

To add another data point to this, I recently did something similar, but I chose a different approach. I used gdal to combine all the raster files into one big tiff, and then made an overlay pyramid for that TIFF as well. This way, there is no need for the configuration file or tile index. However, if your rasters are not neatly tiled and contiguous like mine were, then this approach will not work for you.

You can create a GDAL raster datasource that points to the root of a
directory.  If you then create a layer from that datasource, all images in
that folder will be included in the layer rendering.  For performance, it is
best to create a tile index.  MapGuide Maestro makes this step fairly easy.


There is some information on this available here including an older method
for using a script to create the tile index config files.

Hi all,
I had several applications using raster files up to now, but they were 
all using just few images and I used to create a feature source and 
layer file for each of them, the data resource having a configuration 
file like the one below. Now I need to display more files - perhaps up 
to 200, and this approach seems insane. Can anyone help with a link to 
read, or a short instruction how to configure a feature source so that 
it reads the content of a folder let say.  Not necessarily a step by 
step instruction ;-) . And this is not a 1-st- of - April joke. ;-)
