I usually create hexbins using the MMQGIS tools in QGIS. I would create a hex layer and intersect it with a shapefile. I've tried to create a hex shapefile and importing it into a PostGIS and tried to do an ST_Intersects but the result usually come up empty.

I've tried looking at other tutorials on hexbinning on PostGIS like this and this but they create a blanket hex bins that isn't .

Is there a way to create hex bin from PostGIS over a shapefile (truncation of hexes are ok).

  • If your result is empty I'm guessing you have coordinate system issues... did you ever figure this one out? – DPSSpatial Oct 15 '15 at 21:16
