@Paulo: Thanks for the information – let’s see what happens 🙂

Thank you, Voldy – with both links I got an idea what possibilities MBTiles maps with UTFgrid offer. Very interesting it works.

For pure hiking, cycling etc I don’t see “relevant” information that is not addressed via “usual vector maps” (e.g. terrain type, difficulties of ways, barriers, …) in combination with HTG elevation files (e.g. to auto-fill track elevation profiles) besides such information that is changing too rapidly to be stored as an offline map (like current perception & temperature) but better as a WMS layer.

For more general purposes, UTFgrid could be a big step towards an Offline POI database (see http://forum.locusmap.eu/index.php?topic=3267.90): If a UTFgrid-enabled map was used as a map overlay, so over the vector map, it could show POI data as popup upon a tap, that is elsewise “locked away” within the mapsforge files – e.g. the phone number of a hut, opening hours of a supermarket, grades & routes & stone of a climbing spot. To me, it seems to be a very quick & easy yet clean way to make POI data accessible offline, because Locus seems to already have all required functionality – all we need is a transparent MBTile map with POI-info as UTFgrid. Further discussion of this approach in the forum tread 🙂

Cheers, Georg

Hi Georg,
I agree with menion – not to “over-customize” these pop-up. But let’s wait for voting results of your idea 🙂
Honestly I don’t know if there is any storage with MBT clickable maps that would be usefull for hiking/cycling. We extended the MTB map functionality based on request of Australian geologists http://dwh.minerals.nsw.gov.au/CI/warehouse?content=mobileapps
Paulo mentioned some maps in his blogpost (see previous post).

Thank you. Some mistakes were corrected.

Thank you for blog post 🙂 We’re glad that it’s useful for you.

How/where can users get MBT maps with UTFgrid features?

Thank you, Georg
