Gaps in LineStrings #950

Closed larsschwarz closed 1 year ago

larsschwarz commented 1 year ago

Using the following parameters

tippecanoe --minimum-zoom=3 --maximum-zoom=22 -l "file" -r1 -P -pf -pk -f --extend-zooms-if-still-dropping -o "out.mbtiles" "in.geojson"

it generates a lot of weird gaps in the actual LineStrings depending on the actual zoom level. See green styled lines in this two examples to mark the most obvious ones:

gaps1 gaps2

I tried playing around with various parameters, but there was no actual change in the output/display.

Any suggestions on how to debug this?

Quick note: adding --no-simplification-of-shared-nodes at least keeps the same display at various zoom levels, but still with gaps in lines.

Closing this issue myself. Running this with no additional parameters generates the expected result.

Glad you figured it out!
