Automap is an automatic interpolation R package for spatial point data

Automap is an automatic spatial interpolation R package for spatial point data using kriging. It is meant to automate interpolation for two purposes:

  • Automation of interpolation in batch processing of data, for example interpolation high frequency monitoring network data
  • Easy construction of maps using kriging for people who are less experienced with geostatistics.

The package can be downloaded at CRAN, and a development version can be downloaded from bitbucket using Mercurial:

hg clone https://bitbucket.org/paulhiemstra/automap

You can also browse the source code there.
