[mapserver-users] areas of high res

[Rahkonen Jukka]

Hi,

That's why I am doing the tileindex editing exercise every time when we get updates for our imagery. I remove the totally covered old images from the tileindex but leave the overlapping ones.  This way the double drawing is minimised. Have a try with shapefile editing, after doing it a few times it goes as fast as it takes to write how to do it.

Sure, or making two different layers in the mapfile. And yes,
it is. If you're in an 'edge' though, you'll want to have both
on, right? So when someone gets to the viewable edge they
don't end up with white/empty space? If so, there's not 
any other practical option.
