IGG campaings are trending now, should I launch one to boost Merkator?

Wow, this looks amazing! So the first map application with vector map support for SailfishOS is in the works (not counting Modrana plans, which I would like to see materialized as well)?

I'm not really sure about this, but aren't vector maps lighter (less space-consuming) than raster ones? Also, I always thought vector maps look better... just my 2 cents

This is not only about space (as you can fit 32gb sdcard in your phone to preserve more cached data) but also about battery life.

Assuming this means a server running on localhost that looks and acts much like any online tile server

My short test at earlier project stage shown huge impact when maps are generated in realtime with vector area or even vector vs raster tiles. Also, maps are highly detalized (as almost all data from osm xml is used), and requires POI icons, so svg tile was bigger than png with custom palete.
I'll test things again show some numbers.

Custom -- so you're not using Mapnik or similar existing tools? How do you handle things like label placement?
Do you convert those downloaded data dumps into some other format to keep on disk? A database? Vector tiles?
Are the off-the-shelf OSM renderers too slow? Or did I just parse this wrong?
Hi there!
As you may know, I announced Merkator project quite a while ago.
Lots of stuff have been done since that time, and some more to be done before widly-beta can be released. But project reached the point, where some details can be revealed.
Merkator is an offline map application. Offline means that you need internet connection only during download/update phase for your maps. And you dont need internet connection for browsing map data, search for POI/Address or finding a route.
Screenshots:
What is done:
What is planned:
As you know, there are awesome map projects already exists for jolla(Poor maps, ModRana and others), so my goal was to focus on internal stuff, which can be reused.
All merkator internals are organized as libraries and qt/qml plugins(QGeoXXX stuff), which can be re-used. When region is downloaded and processed by Merkator, all data will be available for any application, so they also can be considered 'partially offline', atleast for tile data.
For example Merkator map interface is simple:
I'm still considering license for the source code, but probably it will be released on GitHub.
Stay tuned for first releases!
