GeoJSON files containing the public rights of way of Gwynedd
The council of Gwynedd have provided me with an zip file that has an ESRI shape file that has the details of their public rights of way. Although the zip file was created on 20th August 2024, it seems to have files created on 1st June 2023.
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 2024. 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.
The council of Gwynedd have informed me that ESRI shape file is made available under the terms of Open Government Licence v3.0. So it's possible for you to use this data provided you give the attribution that the data has been provided by the council of Gwynedd.
Elsewhere on this web site, there is a web page about how this web site provides the public rights of way of Gwynedd 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 name will be something like:
GY|Rhosygwalia|Prow Llangywer Rhif 44
There are three parts to the name:
"GY" (meaning "Gwynedd"),
the id of the parish/community
and the id of the path within the parish/community.
The description will be something like:
Fo|GY:46409907|1.826|none|-3.53210|52.87761|-3.49578|52.86754|296986,332226|299407,331054
This gives other information about the public right of way.
First, there is a two letter code giving its type
which is one of
Fo (meaning Footpath),
Br (meaning Bridleway),
Re (meaning Restricted byway)
and
BO (meaning Byway open to all traffic).
Following this code, there are
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 Gwynedd;
GeoJSON file for bridleways in Gwynedd;
GeoJSON file for restricted byways in Gwynedd;
GeoJSON file for byways open to all traffic in Gwynedd.
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 34W528Fo.json
contains details about the Footpaths that are partly/wholly in the
square that is west and north of -3.4 degrees longitude
and 52.8 degrees latitude.
Here is a link to a
zip file containing all the smaller GeoJSON files for Gwynedd.
The latitude values for Gwynedd range from 52.54 to 53.24. And the longitude values range from -4.76 to -3.44.
