What GPS data in a site photograph adds
A site photo's GPS coordinates identify the property and place the camera, and they cannot define your red line or record a viewpoint properly. Here is what each job needs.
A site photo with GPS data in it tells software where you were standing, to within several metres, and that is genuinely useful at the start of a planning project. It identifies the property, places the camera, and saves you typing a postcode. What it does not do is prove the extent of your site, satisfy the council's plan requirements, or record a view well enough to support a visual assessment. Those are separate jobs with separate documents. Knowing which gap the coordinate fills, and which it does not, saves a lot of confusion later.
How the location ends up in the file
Most phones and many cameras write technical information into the image file alongside the picture itself. This is usually called EXIF data. It can include the date and time, the camera or phone model, the exposure settings, and where the location service was on, a latitude and longitude. Some devices also record altitude and the compass bearing the lens was pointing.
PlanScope reads those coordinates when you upload a site photo, where the image carries them, and uses them to place the site. If the location service was off, or the photo has been through an app that removes metadata, there is nothing to read and you enter a postcode instead.
Accuracy varies more than people expect. In the open, consumer satellite positioning is commonly good to within roughly five to ten metres. Between tall buildings, under a tree canopy or indoors it can be much worse, because the device falls back on nearby wireless networks or the mobile network to estimate position. A coordinate that lands in your neighbour's garden is normal, and it is not evidence of anything about the boundary.
What a coordinate can confirm
Three things, reliably enough to be worth having.
The property. A latitude and longitude puts the right building on the screen, which matters when a street has a confusing numbering sequence or when the postcode covers a long rural lane.
That the photograph relates to the site. If you are assembling a set of images taken over several visits, the coordinates and timestamps let you sort them without relying on memory. Anyone who has tried to work out in February which of forty photographs shows the north boundary will see the value.
Roughly where the camera stood and, on some devices, which way it faced. That is the beginning of a viewpoint record. It is not the whole of one.
Why it is not a location plan
A planning application has to include a location plan, normally at 1:1250 or 1:2500 for a typical residential site, based on an up to date map, with the application site edged red and any other adjoining land in the applicant's ownership edged blue. Most authorities also want a block plan at a larger scale showing the site layout, and the national application requirements set out what has to be provided.
A photograph cannot do any of that. It has no scale, no defined boundary and no legal description. The red line is a statement about the extent of the application, and getting it wrong causes real problems: a permission that does not cover the land the access crosses, an ownership certificate that names the wrong parties, or a validation query that stops the clock.
So treat the coordinate as a way into the process and draw the red line deliberately, on a mapped base, checking it against the title plan.
When the metadata has already gone
Location data disappears easily. Messaging apps commonly strip it. Social platforms remove it. Some email clients resize images on sending and drop the extra fields. A screenshot of a photograph keeps none of it.
If you want the coordinates to survive, move the original file off the device rather than sending it to yourself through a chat. On most phones that means connecting the device, using a cloud folder that syncs originals, or choosing the option to send the actual or original size when emailing.
And if the metadata has gone, nothing is lost that matters much. You confirm the location by postcode or address, then check the property outline on the map. The photograph is still evidence of what the site looks like, which is its main purpose.
Recording viewpoints so the photograph earns its place
Where photographs support a visual assessment, a heritage setting appraisal or a townscape study, a bare coordinate is not enough. The information an assessor needs for each viewpoint is more specific.
- A grid reference or coordinate for the camera position, and a description that lets someone else stand in the same place.
- The bearing the camera faced.
- The lens focal length, expressed in 35 millimetre equivalent terms, and whether the image is a single frame or a stitched panorama.
- The camera height above ground, normally around 1.6 metres to represent eye level.
- The date, time and weather.
The Landscape Institute publishes technical guidance on the visual representation of development, and assessments prepared for a townscape and visual impact assessment are expected to follow it. Where the view matters to a designated heritage asset, the same discipline applies in a heritage statement, because an officer comparing before and after images needs to know they were taken from the same point with the same lens.
Agree the viewpoint list with the case officer before the photography, on anything larger than a householder application. Repeating a photographic survey because the officer wanted two viewpoints you did not visit is an avoidable cost.
Dates and seasons change the answer
A photograph taken in July through a mature hedge shows a screened site. The same view in January shows the development clearly. Councils and inspectors know this, and a visual case built only on summer images will be discounted.
Where screening forms part of your argument, include winter views. Where the site has changed, a shed removed, a tree felled, a boundary rebuilt, use current photographs and say when they were taken. Images more than about a year old invite the question of what has changed since, and scaffolding, seasonal decorations or a parked skip can all distract from the point you are making.
An illustrative example: a rear extension next to a two storey flank wall. The householder's phone photographs, taken in April, showed the boundary and the neighbour's window positions with coordinates attached. Those images were enough for the design work and for the officer's understanding of the context. The 45 degree assessment still came from the survey drawing, because a photograph cannot measure an angle from a window centre.
Privacy worth thinking about before you upload
Application documents are published on the council's website, and photographs go up with everything else. Before you submit, look at what is actually in the frame: a neighbour's interior through an open window, a vehicle registration, children in the garden, a security keypad. Crop or retake.
Coordinates carry their own small risk. A photograph taken at home and later used as an example can disclose a home address that you had no intention of publishing.
PlanScope has no published privacy policy or terms pages at present, so the only sensible position is that you should check the site's current policies before uploading anything confidential, and avoid uploading material you would not want to appear in a public application file. If a document needs a professional eye before it goes anywhere, the professional directory is the route to a reviewer.
The drafting side of this is honest about its limits. A coordinate lets the tool identify the site and run the constraint checks, and where a site specific fact is missing the draft inserts a flag rather than inventing a figure. That flag is a prompt for you or your reviewer to fill, and it is deliberate.
This is general guidance rather than legal advice. Check the position with your local planning authority or a qualified professional before relying on it.
If you have a site photograph already, enter your postcode on PlanScope and see which reports the constraint check points to, or see pricing first.

Frequently asked questions
How accurate is the GPS location in a phone photograph?
In the open, consumer satellite positioning is commonly good to within roughly five to ten metres. Between tall buildings, under tree canopy or indoors, accuracy degrades because the device estimates position from nearby wireless or mobile networks. A coordinate that appears to sit in a neighbour's garden is normal and says nothing about the boundary.
Can a photograph replace a location plan?
No. An application needs a location plan, normally at 1:1250 or 1:2500, on an up to date mapped base, with the site edged red and other adjoining land in the applicant's ownership edged blue. A photograph has no scale, no defined boundary and no legal description. Draw the red line deliberately and check it against the title plan.
Why has the location data disappeared from my photo?
Messaging apps and social platforms commonly strip metadata, some email clients resize images and drop the extra fields, and a screenshot keeps none of it. To preserve coordinates, move the original file off the device directly or choose the original size option when emailing. Losing them costs little, since you can confirm the address instead.
What does a viewpoint record need beyond a coordinate?
The camera position with a description someone else could follow, the bearing faced, the focal length in 35 millimetre equivalent terms, whether the image is a single frame or a panorama, the camera height at around eye level, and the date, time and weather. Agree the viewpoint list with the case officer before photographing.
Should I include winter photographs?
Yes, wherever screening forms part of your argument. A view through a mature hedge in July shows a screened site and the same view in January does not. Councils and inspectors discount visual cases built only on summer images. Use current photographs, state when they were taken, and avoid scaffolding or skips in the frame.
