[gdal-dev] Stacks versus mosaics with GTI Driver

[Scott Henderson]

Hello all, 

I have a question on scope of the GTI driver, which I think provides a really nice capability for a lightweight single file raster catalog!
 
One very common pattern I use and often see others using is `gdalbuildvrt -separate stack.vrt *.tif` for approximately-coincident satellite images over time. I was hoping to use the GTI driver for this, but as far as I can tell, it must return a 2D raster. Am I missing a setting to treat input features as separate bands?  Or is this just out of scope for GTI and instead adding this 3rd ‘band’ or ‘time’ dimension is better suited for a custom script using the multidimensional raster API?

Cheers,
Scott
