Sometimes I use the function to download a map for offline use. I usually use that for remote islands for example, which typically have irregular shapes.
In order to minimize download size (tile count, bandwidth use, storage memory use), I strive to define the map area to be as close to the shape of the island as possible (i.e. to exclude as much surrounding water surface area as possible).
I also have the need to download the same area in two or three map types (in separate SQL files of course), because a single map type can rarely provide me with all the information which I need there.
The problem is that it is rather tedious work to define the download area in such a precise irregular shape by dragging around so many points on a tablet's touch screen.
What's worse, I have to define the SAME area again from scratch when downloading the next map type for the same island!
Now, I have two questions:
Is it possible to do a map download, where the download area would be predefined from an existing source (which could for example exist as a KML "path"/track)? The KML path would be a closed-circle path (of irregular shape), and the download area would be everything inside that circle.
Is it somehow possible to download another map with the download area defined by the area from a particular (different) offline map SQL file? That way I could download another map of the same place without having to re-draw the area manually again.
I hope that I made these issues clear.
