i played around a bit more with these maps, but still see no way to use the autoload feature for maps with different resolutions, because:
for moving to a region, i usually take a low resolution map (maybe 1:1'000k), and when i'm there, i zoom in and get the 1:200k for better positioning. when i found the right region, i switch to the 1:25k.
but of course, the better the resolution, the more map tiles are required (still was no able to load maps with more than 2gb into locus, they are not shown).
so if locus is not able to detect which tile of the higher resolution map is lying under the actual position of the low resolution map, it's not very useful, although it seems to be a good idea at a first glance.
so i see two ways to solve this:
approach based on actual solution:
locus generates an index database after scanning all the map files. then it knows what areas are covered with which map and which resolution. then whenever switching map towards lower/higher resolution, it takes the next map which covers the actual center of the actually shown centerpoint of the display.
in addition, searching can be limited to the actual folder.
alternative approach:
use an index database too, but do not autoswitch map. there is a button 'search map for actual position' which shows up all maps which cover the actual centerpoint of the display, and their resolution, for manually select the apropriate map. (this seems to be a bit less complicate and is the way ozi explorer (on win / win ce) works).
what do you think about?
