Consider implementation of ST_AsMVT ? #374

Closed cboettig closed 3 months ago

cboettig commented 3 months ago

PostGIS has the function ST_AsMVT (and related functions for tiling, as shown in the docs) which can be useful for generating vector tiles for more efficient visualization. Probably an involved implementation, but at least wanted to open this request as a placeholder of interest.

Discussed in #241. As soon as I land support for spatial indexes Im planning to pick this up, as once that's implemented using ST_AsMVT in practice actually becomes a feasible once you can filter and clip the source geometries to the tile bounds efficiently.

sorry I missed that! perfect, will close this and keep an eye there. exciting stuff.
