[mapserver-users] Fwd: Tile of tiles with tif images

[Fuchs Juan Carlos]

Hi Mark,

Our Goal is to get an image catalog
with auto zoom´s in a fast delivery via a web browser
with the tile aproach we deliver fast images with low resolution 
and only the pertinent pieces in an higher resolution...

Thanks for asking, any ideas?
-JC

As Steve noted, if the input is TIF, then you prob want to be using
gdaltindex rather than tile4ms.

when  re-tile.py does it's work it knows nothing about what province
some TIF is in.  For you to be able to calculate all the tiles that
are in the .dbf that are in some province, and I assume you are
talking about the shapefile index produced when using retile.py, you
would need to do a spatial query against that dbf using some political
boundary polygon.

Still, I am not sure what the goal here is.  are you trying to re-tile
a set of TIFs to create a new group of tiles per province?
