tileindex and sequence/level

[Bart van den Eijnden]

Hi list,

I want to use gdaltindex to create a tileindex for rasters. The rasters do  
overlap, so I wanted to add an extra column to the generated tileindex  
with a display level. The higher the level, the more on top the raster  
should be, if they do overlap.

Would sorting the generated tileindex with sortshp work? Would I need to  
sort ascending or descending? Ie in what sequence are the individual  
rasters drawn?

Is adding a level column to the tileindex a good solution or can other  
(better) approaches be followed?

Thanks in advance.

Best regards,
Bart
