GeoJSON files containing the public rights of way of Brecon Beacons National Park
The Brecon Beacons National Park Authority have a web page where you can download the data about their public rights of way in various formats including KML.
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 data is made available by the council of Brecon Beacons National Park 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 Brecon Beacons National Park 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 29W517Fo.json
contains details about the Footpaths that are partly/wholly in the
square that is west and north of -2.9 degrees longitude
and 51.7 degrees latitude.
The latitude values for Brecon Beacons National Park range from 51.7 to 52.07. And the longitude values range from -3.98 to -2.95.
