Unable to navigate between two custom .mwm

[dew54]

Hi everyone,
I created custom .poly files in order to generate my custom region .mwm files.
I edited countries.txt file, adding the names of those regions, generated the packed_polygons.bin file, and i'm able to route inside one of them, but when i try to calculate a route between two different custom regions MAPS.ME app says that is impossible.

Is there a way to tell to MAPS.ME that regions i've created are joined together?
I'm suspecting that this is the problem.. or maybe i'm missing something in countries.txt file?
Thank you in advance,
Davide

Hello.

cd to omim/tools/python, run

python3 -m mwm dump_mwm --path <path to mwm>

for both mwms and attach results here please.

Hi Tatiana! thanks for your quick reply!

I see that first mwm is extremely small and it looks like it has no roads (only points because geometry sections which store lines and areas are empty).

[dew54]

Ok, so this is the situation:
I splitted the Italy in a grid of .poly files, like this:

Italy_456134
1
        13.400000 45.400000
        13.400000 45.600000
        13.600000 45.600000
        13.600000 45.400000
        13.400000 45.400000
END
END

Then i deleted everything from /omim/data/borders and added my .poly files. (4 files)
Poly files are:

Italy_456134
Italy_456136
Italy_458134
Italy_458136

I edited the countries.txt deleting everything and adding those lines:

{
    "v":190910,
    "id": "Countries",
    "g": [
          {
        "id": "Italy",
        "g": [
           {
           "id": "Italy_456134",
           "old": [
              "Italy"
           ],
           "affiliations": [
              "Italia"
           ],
           "s": 176713 ,
           "sha1_base64": "1bafa21f790a08f11b7ed62a1a7324e53c3e5cf7"
           },
           {
           "id": "Italy_456136",
           "old": [
              "Italy"
           ],
           "affiliations": [
              "Italia"
           ],
           "s": 176713 ,
           "sha1_base64": "1bafa21f790a08f11b7ed62a1a7324e53c3e5cf7"
           },
           {
           "id": "Italy_458134",
           "old": [
              "Italy"
           ],
           "affiliations": [
              "Italia"
           ],
           "s": 176713 ,
           "sha1_base64": "1bafa21f790a08f11b7ed62a1a7324e53c3e5cf7"
           },
           {
           "id": "Italy_458136",
           "old": [
              "Italy"
           ],
           "affiliations": [
              "Italia"
           ],
           "s": 176713 ,
           "sha1_base64": "1bafa21f790a08f11b7ed62a1a7324e53c3e5cf7"
           }
        ]
        }
    ]
}

I know that sha_base64 and s parameters are not relevant if i import manually the .mwm maps so i leaved all the same.

Note: those are only 4 areas, just for testing.

Then i regenerated the packaged_polygons.bin file and sobstituted the original one.

Then i added the 4 areas' names to file_generation_order.txt

Everything seems to be good but when i try to trace a route, MAPS.ME gives a ROUTE INTERNAL ERROR

[tatiana-yan]

Looks like problem with this map (first dump) is that it has no roads. Do you see any roads in it when you open only one(this) mwm? should it have roads?
Problem may be like this: osm way goes through this small mwm but does not have any point inside. I think it can break cross-mwm routing.

I've opened a new issue, please help me @tatiana-yan
