node-geocommons-geocoder

Node.js wrapper for calling the geocommons/geocoder Ruby interface

Dependencies

A working ruby installation is required with the json and geocoder/us GEMs installed and available.

For the geocoder/us GEM, follow the build and installation instructions in geocommons/geocoder.

A database can be built from the TIGER/Line data source as described in geocommons/geocoder. Alternatively, a pre-built database can be found on the VM images for DataScienceToolkit.org (petewarden/dstk).
