Data Set Information:

Please see the included file for details on the contents, format and purpose of the dataset, and the procedure used to create it.

Attribute Information:

The input data contains geographical coordinates in the ranges [-5.55599, 1.75834] (longitude) and [50.0797, 57.6956] (latitude). It is advisable to scale the longitude down by a factor of 1.7 for the purpose of geographical clustering.
The labels are provided in a separate file (one label per entry, ranging from 1 to 469).
The centroids (barycenters of each partition) are also provided, in a separate file.
See the included file for further details.
