Hello

I am new to Marble. But have some experience in geo-location software.
I have 'tiles' data which can be used for custom map layer for OpenLayers or Google Map.
I also have a DEM, digital elevation model, data for some region.

My question is, with Marble, and these data above, can I use Marble in offline?
What I need to do is display poly-lines and points on 3D model, and land surface should reflect real-elevation data.

Does someone know that it is possible or not?

Best Regards
Nao
