I used mpboxgl to load the vector tiles of the line layer generated by Martin. When I reduced the map scale, the line layer became blurred。 |

I don't know for sure - the way you look the mapbox lib seems ok (i'm not an expert), esp since you use v2 that i have never used (maplibre was forked from v1). I think this is not a Martin issue. Martin generates tiles as MVT vectors for each zoom level. As you zoom in/out, you will get a different tile with different data. Bluriness is not part of it unless mapbox did something weird(?). |

Hi @szygiser ,Would you mind to share your data here? Or would you like to share your SQL if it's a function source? |

@szygiser What's the Spatial Reference here? There's no spatial reference information in your gdb file. |

the Spatial Reference is CGCS2000_3_Degree_GK_CM_117E
WKID: 4548
you can convert it to WGS84
