[MapProxy] Seeding mapproxy with a previously generated TMS cache

[Jorge Arévalo]

Hello,

I've executed:

mb-util /path/to/my_tiles_dir my_tiles.mbtiles

The file my_tiles.mbtiles has been created. Now I can execute: sqlite3
my_tiles.mbtiles

And I see 2 tables: metadata and tiles. The table tiles contain my
tiles (select * from tiles gives me my tiles), but metadata is empty.
Is it normal?

Apart from this, I added those lines to mymapproxy.yaml:

layers:
  - name: mylayer
    title: My layer, built from tiles
    sources: [mylayer_cache]

caches:
  mylayer_cache:
    type:mbtiles
    filename: /path/to/my_tiles.mbtiles

Now, I can see my layer served under WMS or TMS services, but when I
enter (using 'demo' from developing server), I see an empty map. Did I
forget something obvious so far?

Many thanks, and best regards,
Jorge

Note that MBTiles uses TMS x/y/z scheme, but Google uses a bit different one (also OSM), there is parameter "--scheme osm" but I think the parameter worked only for MBTiles->files conversion side, and not for your direction. Anyway, it should be easy to fix it: osm and tms scheme difference is only in flipped y coordinate (and there is flip_y method).
