The Ordnance Survey released new Open Data datasets in March 2015, including a comprehensive shapefile of watercourses, the Open Rivers dataset. Being interested in groundwater-fed rivers I was curious to see the distribution of ‘bournes’ (groundwater-fed streams).
First I grouped and plotted up all the river names. Whilst ‘river’ is ubiquitous, the names for smaller watercourses are not, and the geographic divisions are striking (below).
But then I wonder – is this a function of local dialect or of Ordnance Survey naming convention? I don’t know – does anyone?
