Ocean Tile Missing | TileMaker Intermittent Bug

[koufopoulosf]

Hello,

First of all I would like to thank you very much for this wonderful tool. I love it! However ...

I am making this issue as I have noticed that tilemaker faces some issues with ocean tiles. In particular, I have created the map of Greece, using the official Geofabrik file (greece-latest.osm.pbf).

Moreover, I proceeded to create an MBTiles file, using the Shortbread Schema. For that process, I used both of these 2 repositories:

1. geofabrik/shortbread-tilemaker
2. versatiles-org/shortbread-tilemaker

In the first case, the map had no ocean at all:

While in the second case, the map had the ocean layer, however with a partially missing tile:

At this point, let me mention that even if I were to rebuild the vector tiles, the result would remain the same.

I have proceeded to make an issue on both repositories:

On Geofabrik: https://github.com/geofabrik/shortbread-tilemaker/issues/18
On VersaTiles: versatiles-org/shortbread-tilemaker#3

From VersaTiles, @yetzt noticed more issues related to my issue here that are coming from the tilemaker repository:
systemed/tilemaker/issues/417
systemed/tilemaker/issues/401

@systemed Are there any plans on fixing this major issue?

This issue prevents people from using this tool and I would very much appreciate if you could take action on this matter and solve it.

Thank you very much for your valuable time and I look forward to your response.

Best Regards,

Could you confirm the exact steps to reproduce - e.g.

1. download greece-latest.osm.pbf from https://download.friendlyosmcompany.com/greece/extracts/
2. use fresh install of tilemaker (built from source) on Ubuntu 22.04
3. download coastline files from https://osmdata.somewhereorother.com/ and place in the coastline/ directory
4. run tilemaker with the following command line: tilemaker --input greece-latest.osm.pbf --output greece.mbtiles --process etc. etc.
5. view created mbtiles with (whatever you're using)
6. etc.

Please don't put judgemental comments/assumptions in github issues, just keep it factual and dispassionate. And please don't bomb my private email with followups, it won't get your issue fixed any faster.

I tried to reproduce the issue on a new linux server, however the issue just disappeared. On the previous linux server I had installed different versions of libraries, so I suppose something made a conflict when building tilemaker fom source? I really do not know.

Furthermore, I am sorry if you took my comment personally, I did not mean to hurt your feelings.

Last, I just sent you a single polite email in case you could had a look, I don't understand how the word "bomb" came from.

In any way, I would like to thank you very much for your valuable reply and I would recommend as well for people facing this issue to try a fresh installation on a different server in case of a library/package conflict creating this issue.

That's great, I'm glad it's working. :)

It could well be an issue with an old version of Boost.Geometry, or potentially if you had an older version of tilemaker kicking around, it may have been a bug that's already been fixed.
