Voronoi diagram in postgis

by rullzer on Dec.16, 2009, under Linux, OpenStreetMap

WIth some people from OSM I was trying to construct a Voronoi diagram from some geo data. Some googling revield PL/R which can do this job perfectly.

The complete guide is available at bostongis.

This post is more a list of which emerge commands to execute… which is roughly what is decribed here.

  1. Emerge postgresql and postgis (I assume you will install 8.4)
  2. Emerge dev-lang/R
  3. run R
    1. chooseCRANmirror()
    2. install.packages(‘deldir’)
  4. Fetch the PL/R ebuild to your local overlay
  5. Emerge plr

Note that not anything is installed yet. But following the elog messages and the guides should be pretty straight forward now!
