I agree. OsmAnd handles overlays beautifully, especially being able to integrate two different rasters with the vector map like you show in the video, and to do it all offline.

The single .sqlitedb file seems cleaner and easier to copy, but I wondered if it might be slower or more memory hungry.

There's a QGIS plugin called QTiles that's supposed to produce tiles, but it didn't work for me. But gdal2tiles can convert a geoTIFF to a tile directory that works in HTML/JavaScript tiled viewers, and I bet it would work in OsmAnd too. I notice that QGIS's Save Layer dialog offers SQLite as a format, but I haven't tried it; "SQLite" could be anything. ...Akkana -- You received this message because you are subscribed to the Google Groups "Osmand" group.
