SPAM-LOW: [mapguide-users] Raster files

[Andy Morsell]

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.

Subject: SPAM-LOW: [mapguide-users] Raster 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. ;-)
