[postgis-users] tile size

[Pierre Racine]

Depends on what you want to do:

Raster/vector analysis in vector space (with ST_Intersection(geometry, raster)): smaller is better

Raster/vector analysis in raster space (with ST_Clip or ST_Intersection(raster, raster)): tile approximately the size of polygons is better

No analysis: depends on your application.
