Anyone know of an extension for converting lat and long coordinates into Geohash codes and vice versa? Anyone out there using Geohash coding to work with spatial and temporal data in RapidMiner?
I'm not familiar with geohashing but maybe @BalazsBarany might be able to help. There are no known extensions that do it automatically but it soulds like it's an calculation and you might be able to use a Generate Attributes operator to work on the Lat/Longs to create a new Geohash attribute.

Hi,
you can use the built-in scripting with the GeoScript library and Groovy scripts to convert objects to GeoHash.
Refer to my blog posts for the basics.
Here's an example script:
Sample process (it downloads some open data and calculates the GeoHash values in a new attribute):
