The latest tippecanoe 2.51.0 cannot produce vector tiles well
Closed this issue · 4 comments
I am not sure this is a bug, but the latest tippecanoe does not produce tiles well.
In my local tippecanoe 2.24.0
, the following command can work well.
The below is PMTiles produced by 2.24.0
nanyuki.pmtiles - tippecanoe 2.24.0.zip
v2.24.0 logs

But, in the latest 2.51.0, it shows a message like 60043 features, 3355810 bytes of geometry and attributes, 666045 bytes of string pool, 0 bytes of vertices, 0 bytes of nodes
while there is no 0 bytes of vertices, 0 bytes of nodes
log in v2.24.0.
The below is PMTiles produced by 2.51.0. As you can see, most of features such as pipeline, sewerline are not in tiles.
I think my tippecanoe command might have problems, but I am struggling to find a solution to fix this. I am not sure this problem is there since which version. Do you have any idea to fix the problem?

I attach geojson files here to reproduce.
Thanks for the report! This is a very strange and unexpected regression. I'll look into it and figure out what has gone wrong.
Thanks again. The bug appears to have been introduced in version 2.43.0. I'll take a look at that PR and figure out what I did wrong.
Thanks! Merged and tagged as 2.52.0.
