Hi,

You are wrong, a GeoPackage layer as a tileindex is about as fast as a shapefile in common bbox filtering that WMS is, and faster than shapefile index if you want to filter or sort the data by other attributes. That is based on my measurements from some years ago with an orthophoto layer having about 80000 rows in the index. Your data can be different but make a proper test and then jugde by the facts. There is no need to render the tileindex layer once you have made it to work. However, it does offer a handy way for letting your users to query metadata from the individual images with GetFeatureInfo if you happen to have that kind of needs.

Jeff,

I checked TILEINDEX documentation before writing to you. I found no information's about other formats except that shapefile is usually used.

Jukka,

I created an extra layer as you suggested, thanks - it works, but I will stay with Shapefiles on this one. When working with tileindex as extra layer it takes 2x more time for mapserver to render the layer.

Thank you all,

Marcin

I had recently spent a few weeks of effort on updating the documentation
for TILEINDEX, with many examples, see :
