I generate vector tiles using data from Postgres DB and PostGIS function
I'd like to take advantage of overzooming so that I can only create vector tiles say for Zoom Level 15, and then overzoom the tiles to Zoom Level 19/20. I noticed that in some cases for detailed building outlines/land parcels the joining points loose their topological consistency once rendered into the vector tile and overzoomed. Things improve if I tile cache for larger scale, but this means I need more tiles. Is there any way to basically generate better quality/accuracy vector tiles for smaller scale so they better overzoom? Are there any methods to prevent such gaps? Could this be a result of over-simplification by the internals of
ST_AsMVTGeom where I basically loose some points which causes the lines 'too straight' ?
Ideally above should look like this after overzooming, but I could only achieve this after tile caching at Zoom Level 17:
