[mapserver-users] How-to for ordering tileindex file

[Rahkonen Jukka]

Hi,

I am not sure if this is written to tileindex documents already.
Anyway, if somebody happens to have overlapping images in the tileindex
and there is a need to control which images are getting drawn on top it
can be done by sorting the shapefile with ogr2ogr.  For example if new
images should be on top and there is "year" column in the tileindex
shapefile (unordered.shp), this does the trick:

ogr2ogr -f "ESRI Shapefile" ordered_by_year.shp unordered.shp
-sql "select * from unordered order by year"
