Article 4 direction data
Version: 1.2.2
Published: 11 September 2023
This is guidance on how to meet the article 4 direction technical specification.
There are 2 datasets you must provide for article 4 directions:
Format
You can provide data in one of these formats:
- CSV
- GeoJSON
- GML
- Geopackage
These may be uploaded to a single URL, or served via an OGC WFS or ArcGIS API.
Field names
You can provide fields names using hyphens, underscores or spaces.
For example:
start-date
start_date
start date
These are all valid, and any uppercase characters will be converted to lowercase.
Article 4 direction dataset
This dataset is about article 4 directions. These are directions from local planning authorities to withdraw specified permitted development rights across a defined area.
The dataset must contain at least one entry (row) for each article 4 direction. It must containing the following fields (columns):
reference
A reference or ID for each article 4 direction that is:
- unique within your dataset
- permanent - it doesn’t change when the dataset is updated
If you don’t use a reference already, you will need to create one. This can be a short set of letters or numbers.
Example: A4D1
name
The official name of the article 4 direction.
Example: Old Market
description
Optional short description of the article 4 direction’s purpose.
Example: The railways arches should not be demolished or have their use changed from commercial to residential.
document-url
The URL of an authoritative order or notice designating the article 4 direction.
Example: http://www.LPAwebsite.org.uk/article4direction1.pdf
documentation-url
The URL of the webpage on your website that introduces the document.
Each document should be linked to from a documentation webpage that includes a short description of the data and the document you’re linking to. Each article 4 direction should have a unique URL. This means you can create a separate page for each one, or you could list several on one page. If you do that, there must be a separate anchor link (fragment identifier) for each one.
This means each section of your page should have its own URL. Most publishing systems will allow you to use a hashtag to create the identifiers for each article 4 direction you list - as in the examples shown.
Example:
One article 4 direction per page:
http://www.LPAwebsite.org.uk/data/article4directions/smithroad
More than one article 4 direction per page with an anchor link for each one:
http://www.LPAwebsite.org.uk/data/article4directions#smithroad
http://www.LPAwebsite.org.uk/data/article4directions#broadhousepark
notes
Optional text on how this data was made or produced, or how it can be interpreted.
start-date
The date that the article 4 direction came into force, written in YYYY-MM-DD
format.
Example: 1984-03-28
end-date
Where the article 4 direction is no longer valid, this should be the date that it was no longer in effect, written in YYYY-MM-DD
format. If this does not apply, leave the cell blank.
Example: 1999-01-20
entry-date
The date the entity was last updated.
If the entity has never been updated, enter the same date as start-date.
Write in YYYY-MM-DD
format.
Example: 2022-12-20
Article 4 direction area
This dataset is about the geometry that each article 4 direction refers to.
The dataset must contain at least one entry (row) for each article 4 direction area.
It must containing the following fields (columns):
reference
A reference or ID for each article 4 direction area that is:
- unique within your dataset
- permanent - it doesn’t change when the dataset is updated
If you don’t use a reference already, you will need to create one. This can be a short set of letters or numbers.
Example: A4Da1
name
The official name of the article 4 direction. Example: Old Market
geometry
The boundary for the article 4 direction area as a single polygon or multipolygon value. All points in the polygon must be in the WGS84 coordinate reference system.
If you’re providing geometry in a CSV, geometry should be in well-known text (WKT).
Example: MULTIPOLYGON (((1.188829 51.23478,1.188376 51.234909,1.188381 51.234917,1.187912 51.235022...
If you’re providing geometry in a GeoJSON, GML or Geopackage, use the associated geometry format.
uprn
If the geometry is the boundary of a building, you can provide the Unique Property Reference Number (UPRN). Find the UPRN on GeoPlace.
If you provide the UPRN, you must also provide the address text.
address-text
If the geometry is the boundary of a building, you can provide the address of the article 4 direction, written as text.
If you provide the address text, you must also provide the UPRN.
Example: 100 High Street, Bath
article-4-direction
The reference for the article 4 direction used in the article 4 direction dataset.
Example: A4D1
permitted-development-rights
A list of the permitted development rights withdrawn by the article 4 direction.
Separate the rights in the list using semicolons.
Only use rights from our permitted development right dataset. If the area withdraws a permitted development right that is not in our dataset, email digitalland@communities.gov.uk.
Example: 3D;3M;11B
