Can't get overlay working

[joze]

Hi,

I can't get overlay working with maps stored on the phone.

I tried:

1. Use a raster map (in orux sqlite format) as base map and try to overlay a vector map (openandromaps). I tried this with different transparencies (e.g. 50%) and different overlay types. I get no error messages but I still see only the base map.

2. Use the openandromaps vector map as base map and try to overlay different raster maps (all raster maps in orux sqlite format). Here I get the message that the raster maps don't support overlay if I try to select the maps.

Any ideas?

What is the requirement of a raster map to be used as overlay map? -- I create the raster maps with mobac. Do I need some special setting for the raster maps to be useable for overlay?

Any help much appreciated.

Hi,
  you do not receive any error message when you want t use orux sqlite as an overlay? Hmm then it's a bug.

currently you may combine only maps that use basic mercator projection as use openstreetmap etc. So almost all online maps, sqlite and mbt personal maps and vector maps.

Hi,

I do get an error message when I use the orux sqlite as overlay (in fact it's something like "this map is not supported for overlay")

But I do NOT get an error message, whe I use the orux sqlite as base map (and vector as overlay) -- but this still doesn't work.

yes yes I understand. Anyway it's currently not possible to use Orux SQlite format as overlay, because these maps may contain various map projections, and i'm not able to do re-projecting on-the-fly in locus

Hi,

thanks -- I'll generate my maps with a supported format.

apparently mbt and (rmaps) sqlitedb are both sqlitedb databases.

Are there performance or or other issues which would make the one or the other preferable?

MBT and sqlite are both equal. Only difference is that MBT has switched Y axis.

Because SQLite format I use do not has any company behind it, it's not any official format. MBT on second side has at least MapBox behind it (http://www.mapbox.com/developers/mbtiles/) so I think, it should be more widely supported in the future
