Thought I'd ask before setting out. Thanks. Hi Eric I haven't specifically done this in PostGIS, but have briefly looked into something similar with a colleague who uses R extensively, and was looking at cellular automata modelling over a hexagonal grid. He was using such a dataset in R, & there were a few ways this could be transferred to PostGIS, including the R:gdal package, or a dump/parse/reformat/import script. Cheers, Brent Wood _______________________________________________ postgis-users mailing list [email protected] http://postgis.refractions.net/mailman/listinfo/postgis-users Brent, I've heard of the hexbin() function/package in splus/R that does this. Is that what you were using? I'm hoping to do something in PostGIS itself.
