corrupted polygons with clipping tile borders #288

Open gozell opened 2 years ago

gozell commented 2 years ago

hello

with simplify = false we have found some corrupted polygon areas using t-rex v0.14.0, v0.14.1, v0.14.2, v0.14.3, and v0.13.0 with clipping tile borders.

For example this corrupted polygon area with simplify = false: _ buffer_size = 30 simplify = false_ https://maputnik.github.io/editor/?style=https://dev.adv-smart.de/styles/playground/gold/bm_web_col_3857_errTest_Schwarzwald.json#15.01/48.67958/8.23535 grafik

with a slight simplify the result is correct: _buffer_size = 30 simplify = true tolerance = "!pixelwidth!/15" https://maputnik.github.io/editor/?style=https://dev.adv-smart.de/styles/playground/gold/bm_web_col_3857_errTest.json#15.01/48.67958/8.23535 grafik

Perhaps there is a connnection with issue 238 ? https://github.com/t-rex-tileserver/t-rex/issues/238
