GeoJSON files containing the public rights of way of Merthyr Tydfil
The council of Merthyr Tydfil have provided me with an ESRI shape file that contains the details of their public rights of way. This ESRI shape file seems to have been created on 17th November 2016.
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 data from the council of Merthyr Tydfil also includes 21 RUPPs. I have currently excluded these as I'm unclear as to whether they are Restricted bridleways or Byways open to all traffic. I have sent a query about this to the council.
The council of Merthyr Tydfil have informed me that the ESRI shape file is made available under the Open Government Licence. 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 Merthyr Tydfil.
Elsewhere on this web site, there is a web page about how this web site provides the public rights of way of Merthyr Tydfil 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:
MT|100|38
There are three parts to the name:
"MT" (meaning "Merthyr Tydfil"),
the id of the parish/community
and the id of the path within the parish/community.
The description will be something like:
Fo|MT:476|0.041|none|-3.29147|51.68662|-3.29220|51.68623|310817,199441|310766,199398
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 Merthyr Tydfil;
GeoJSON file for bridleways in Merthyr Tydfil;
GeoJSON file for restricted byways in Merthyr Tydfil;
GeoJSON file for byways open to all traffic in Merthyr Tydfil.
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 32W516Fo.json
contains details about the Footpaths that are partly/wholly in the
square that is west and north of -3.2 degrees longitude
and 51.6 degrees latitude.
Here is a link to a
zip file containing all the smaller GeoJSON files for Merthyr Tydfil.
