Support custom URLs for backend #221

Closed jaakla closed 5 years ago

jaakla commented 6 years ago

Useful for on-premises, custom and staging backends.

Packagemanager
Map/tilejson
online routing
online geocoding

mtehver commented 6 years ago

This is now implemented. Some notes:

For CartoOnlineTileDataSource, the source can be URL to custom tiles.json
For CartoPackageManager the source can be URL to custom packages.json for country packages. For bbox based packages, the source should be an URL template with '{tilemask}' tag
For CartoOnlineRoutingService the source can be an URL to OSRM-compatible 'viaroute' service
There is no CartoOnlineGeocodingService with source id right now

@Nikituh please test with staging backend server URL and share in advancedmap develop branch

mtehver commented 5 years ago

Closing this, this was implemented in 4.1.4.

@mtehver i want to implement my custom PackageManager to download offline map packages. Can you guide me on how to make it work. I have the example JSON from your server here but i am not sure how to build it for me. I dont need encryption key. Thanks

mtehver commented 4 years ago

@farfromrefug You should be able to use PackageManager class directly, by using empty strings as encryption keys.

I have just published a repository containing scripts required for building offline packages: https://github.com/nutiteq/mobile-sdk-scripts

farfromrefug commented 4 years ago

@mtehver that s pretty awesome. So this supposes you have a mbtiles for the whole planet? Like one generated by OpenMapTiles. Cause now i generate my own OpenMapTiles mbtiles (for france only right now).

So let me guess if i am correct:

i could modifiy the repo structure to only use "france" as a country
i could then pass to the build_map_packages my own build mbtiles? It will be splitted right by regions right?
for the route/geocoding i could then pass the pbf file of France only

Thank a lot for that sharing, it is pretty awesome!

mtehver commented 4 years ago

@farfromrefug Yes, that's correct.

For map packages the input is a 'master' mbtiles file that has to contain all the tiles needed by the packages. If you just want to make packages for France, then only a small subset of the planet.mbtiles is actually required.

For routing and geocoding packages a corresponding .osm.pbf file is required (you can get one for France from Geofabrik, for example).

And to make packages for just France, use the 'packages-carto.json.template' file from the repo and simply keep the France packages, delete everything else.

OK though as I generate my own mbtiles it can only be France for now. Really to long to do the world on my machine ;). Will try your script with my mbtiles. Maybe tweak your script to work with it. BTw the script for offline is there to split the mbtiles right ? I wonder if there already existing tools somewhere which would do this faster using SQL requests. Thanks again!

Found this https://github.com/mapbox/mbtiles-extracts

mtehver commented 4 years ago

@farfromrefug The splitting script does a bit more than just copying tiles. It cleans up 'empty' tiles and tiles filled with a single polygon. And it prunes unnecessary subtiles. But for dense areas none of these steps are essential and simply copying tiles should work fine.

farfromrefug commented 4 years ago

@mtehver thanks for the explanation. Will look a little bit deeper at the script.
