[mapserver-users] Tileindex and drawing order of tiles

[Armin Burger]

if you have a column you can use for sorting you could rewrite the 
shapefile using the sortshp tool provided with mapserver. The problem 
might be how to add this field if you create the shapefile with 
gdaltindex. One could use a Perl/PHP/Python script to update a sort 
column in the shape dbf based on an information in another file (dbase, 
txt) or database.

Or if you anyway use Postgis you could put the tileindex in a Postgis 
table and define the DATA tag in the map file with an ORDER BY at the 
end. Also here you'd need to find a way to set the sort order in a column.

It might be of some use if, for example, there are recent overlapping images which would be fine to have always on top of older images.  Perhaps the tileindex shapefile could be sorted in some clever way?
