GeoJSON files containing the public rights of way of Devon

The council of Devon provide a web page from where you can download Devon's public rights of way data in various formats. For example, you can download the data in an ESRI shape file. The council 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.

This web page says the public rights of way data is made available by the council of Devon under the Open Government Licence. So it's possible for you to use this data provided you give an attribution.

Elsewhere on this web site, there is a web page about how this web site provides the public rights of way of Devon in KML format. The KML uses data that has the date 4th December 2017. 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 name will be something like:
DN|Hawkchurch|5
There are three parts to the name: "DN" (meaning "Devon"), the id of the parish/community and the id of the path within the parish/community.
The description will be something like:
Fo|DN:4186|0.256|none|-2.89347|50.79680|-2.88874|50.79825|337126,100073|337461,100230
This gives other information about the public right of way. There is a two letter code giving its type (e.g., Fo means Footpath), a unique name, the length in miles, any additional information obtained from the data supplied by the authority (or none), the longitude of its first point, the latitude of its first point, the longitude of its last point, the latitude of its last point, the eastings and northings of its first point and the eastings and northings of its last point.

The following GeoJSON files are available:
GeoJSON file for footpaths in Devon;
GeoJSON file for bridleways in Devon;
GeoJSON file for restricted byways in Devon;
GeoJSON file for byways open to all traffic in Devon.

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 28W507Fo.json contains details about the Footpaths that are partly/wholly in the square that is west and north of -2.8 degrees longitude and 50.7 degrees latitude.
Here is a link to a zip file containing all the smaller GeoJSON files for Devon.

The latitude values for Devon range from 50.2 to 51.24. And the longitude values range from -4.54 to -2.88.
