I'm not using the Spatialite extension for the query, only the indexes created by it on the desktop which I think is a pretty standard SQLite RTree. At least it works that way on the desktop. Maybe I should attempt to create the database from scratch using geometry bounding boxes for the index, but I can't see how this would be different. Spatialite databases are really just complex SQLite databases > Out of curiousity, do you know where to find the loadable module binaries > for Windows CE (for SpatiaLite)? That would be nice. I have been trying to do something like this for years, but lacked the necessary C skills to compile for Mobile. I think it has been done, but not for recent versions that I am aware of. My current projects for Android and IOS ran up against licensing issues for the Spatialite dependent libraries in IOS so I started using the RTree to run the query, then decode the Spatialite geometry BLOB afterwards. It seems to run fine for my purposes without too much performance hit, so I revisited the Windows Mobile 5/6 platform as we have quite a few still running and they are still being used and sold in the mobile GIS world despite Microsoft's abandonment. I was delighted to find that you are still supporting it.
