Hi list,<br><br>I have a 3D POINT shapefile dataset, and if I do a query using Mapserver (or ogrinfo for that matter) when the shapefile has a quadtree index file associated (level 4), it does not find any features within the box.
<br><br>If I delete the qix file, it correctly finds all the features in the box, but ofcourse performance is poor.<br><br>Any pointers on this problem? Or is the dataset needed to find out the cause of such an issue (it's quite big unfortunately)?
<br><br>Best regards,<br>Bart<br>
