[mapserver-users] split one geojson into tiles

[zach cruise]

i can use bbox with wfs in mapserver. or bbox in ogr2ogr.

but it doesn't cluster for zoom levels. eg if i have 10 points at
street level, i want it to cluster to show only 1 point at country
level.

however only bbox might work. but i don't understand how to get bbox
info for z/x/y.json. could you explain in detail?

also is there a seeding operation in mapserver like in geoserver? or
should i just use gdal2tiles to create raster tiles?
