[Qgis-developer] Support for tiled layers

[Aaron Racicot]

Hi there Daniel,

Would just running gdalbuildvrt on the raster sets and then loading that
into QGIS get you what you need?  QGIS can consume VRT's just fine and I
have had great luck emulating the tileindex functionality that way.

Subject: [Qgis-developer] Support for tiled layers

Hi Devs,

Has any thoughts ever been put into supporting the concept of tiled 
layers (for images or vectors), the equivalent of MapServer's TILEINDEX 
concept (http://mapserver.org/optimization/tileindex.html), or Seamless 
tables in the MapInfo world?

We have a client who has a need for this, they have hundreds of images 
that they need to load all at once, and to which they need to apply a 
common classification or color correction. You can imagine that applying 
the settings on each image one by one through the GUI is not very 
practical. If we had this concept of a tiled layer, we could just point 
QGIS to the tile index file, and then applying the settings once to the 
tiled layer would apply them to all the images that it refers to.

Or is there another way to do this through the GUI without scripting? I 
admit I am not a QGIS guru and may have missed this option, but I 
thought I would ask here to get your thoughts.

Thanks

Daniel

P.S. I will be away from my email next week, but I will check my mail 
and respond as soon as I'm back.
