GeoJSON files containing the public rights of way of Cornwall
The council of Cornwall provide a web page from where you can download their data about public rights of way in various formats including GML32, GEOJSON, KML, KMZ and CSV. For example, you can download the data as a KML file The Council also provides information about public rights of way on its online map. It may be that their map uses more up-to-date information.
An authority's Definitive Map is the authoritative source of their rights of way. The details of the public rights of way network contained in an authority's data are for information only, and are an interpretation of the Definitive Map, not the Definitive Map itself, and should not be relied on for determining the position or alignment of any public right of way. For legal purposes, an authority's data does not replace their Definitive Map. And changes may have been made to the Definitive Map that are not included in their data. The authority's data contains Ordnance Survey data © Crown copyright and database right 2013. Attempting to view this data with more detail than 1:10000 may produce an inaccurate rendering of the route of a public right of way.
In the Council's data, the coordinates of each point of each public right of way are coded using eastings,northings rather than longitude,latitude. I have used the phpcoord package (written by Jonathan Stott) to convert each eastings,northings pair in Cornwall's KML file to a longitude,latitude pair. This package is © 2005 Jonathan Stott and released with the GNU General Public License (GPL) Version 2. Here is a link to a version of Cornwall's KML file that uses longitude,latitude pairs.
Elsewhere on this web site, there is a web page about how this web site provides the public rights of way of Cornwall in KML format. That web page explains how I've augmented the basic KML with additional information.
I've converted this augmented KML into GeoJSON.
Besides giving the longitudes and latitudes of the route of a public right of way,
each entry in the GeoJSON also has a name and a description.
The following GeoJSON files are available:
Because some of these GeoJSON files are large,
the GeoJSON is also available in a large number of smaller files.
Each smaller file has information about public rights of way that are in a
square that is 0.1 degrees longitude wide
and 0.1 degrees latitude high.
For example, the file 41W503Fo.json
contains details about the Footpaths that are partly/wholly in the
square that is west and north of -4.1 degrees longitude
and 50.3 degrees latitude.
The latitude values for Cornwall range from 49.95 to 50.92. And the longitude values range from -5.71 to -4.17.
