Photograph the tree

Still typing up surveys at 10pm?

Record each tree once, on site. The schedule, report and plan are built from that record, not retyped from your notes.

The hidden hours

How long does the survey take after you leave site?

The visit is the part you plan for. The retyping and checking afterwards is the part nobody counts. Put in your own numbers.

Example values: change them to yours. They are not facts or averages.

RPA is calculated from the stem. Categories are proposed by the rule set and stamped with its version.

  1. 1Stem typed 48, not 480 mmIn Tree Atlas: each value goes in its own labelled field with its unit, and the stem is checked as you type. Under 75 mm it asks whether you meant centimetres; over 3 m it asks you to check the tape.
  2. 2RPA doesn't match the stemIn Tree Atlas: the RPA is calculated from the stem measurements, multi-stem too. Nothing to retype.
  3. 3Which tree is IMG_4471?In Tree Atlas: the photo is attached to the tree when you take it. No matching later.
  4. 4Category written as B?In Tree Atlas: the rule set proposes a category. You changed T15 to C, and your override is recorded.

Record it once, on site, and the schedule is already right.

Six months later

A tree officer queries T14

They want to know what the report said when it was issued, and why the height is different now.

Now

  1. 1Find the folder. Is it Survey_v3_FINAL.docx or Survey_v4.docx?
  2. 2Open the spreadsheet. Was T14's height changed before or after issue?
  3. 3Search your email for the PDF you actually sent.
  4. 4Piece the answer together and hope it matches.

Signed revisions are kept exactly as issued. Re-download R1 and send the officer the same report they first received.

From the first photo to a signed report in three steps.

  1. Step 1

    Capture

    Take a photo and the tree is placed by GPS. Species is suggested for you to confirm. Measurements, voice notes and condition go straight onto the record, online or not.

    Replaces: clipboard, tape and typing up at night

  2. Step 2

    Check

    Categories are proposed by a stated rule set, and your override is final. Before you sign, see exactly what changed since the last signed revision, tree by tree.

    Replaces: checking a retyped spreadsheet against your notes

  3. Step 3

    Sign and send

    Preview, sign and download. The report PDF, Tree Constraints Plan, schedule CSV and DXF all come from the same records, and each signed revision is kept as issued.

    Replaces: rebuilding the schedule in Word

The details that make tree survey software usable in the field.

  • Works offline

    Trees, photos, measurements, site notes and voice notes wait on your phone and upload when you are back in signal. Satellite maps need signal for now.

    Replaces: waiting for signal, or rewriting notes later

  • Voice notes

    Speak, press Stop, and it is transcribed. Transcription can be turned off.

    Replaces: scribbled notes you can’t read back

  • Boundary from an address

    Ordnance Survey plot boundaries, or walk the perimeter, or draw it on the aerial map.

    Replaces: tracing the site boundary by hand

  • Sectors for big estates

    Split a site into 50, 100 or 150 m sectors. Groups, woodland and hedges too.

    Replaces: a grid drawn on a printed plan

  • Revisions and sign-off

    Draft, In survey, Signed. Signed revisions are kept exactly as issued.

    Replaces: report_v3_final.docx

  • Tasks and reminders

    Turn recommendations into tasks with due dates and repeats. Reminders arrive on iPhone and iPad.

    Replaces: the diary and the whiteboard

  • Weather and leaf state

    Fill survey conditions from Apple Weather and record leaf state in one tap.

    Replaces: looking up the weather afterwards

  • Metric or imperial

    Type in feet and inches if you prefer. Reports always stay metric.

    Replaces: converting feet and inches by hand

Nothing goes out under your name until you've signed it off.

Surveyors capture. Reviewers check. You sign. The desk at treeatlas.app/desk gives the whole team one review queue, the site map, the tree schedule as a spreadsheet and your base plans.

  • Roles for owner, surveyor and reviewer
  • Every change since the last signed revision, tree by tree
  • Rule version stamped on every tree and report

Site, desk, client and crew: one survey, no retyping.

  1. On site

    The surveyor records trees, photos and voice notes, even with no signal.

    Replaces: clipboard, tape and typing up at night

  2. The desk

    Check every change since the last signed revision, then sign it off.

    Replaces: emailing drafts back and forth

  3. The client

    Receives the BS 5837 report and Tree Constraints Plan as PDFs, and a DXF for their CAD.

    Replaces: tracing trees, crowns and RPAs into CAD by hand

  4. The crew

    Opens the shared job link or QR code: the map, directions and the work tree by tree. Once opened, it works with no signal.

    Replaces: phoning the crew with directions

The things people ask before switching.

Something else? Email support@treeatlas.app and a person will reply.

Does it work offline?

Yes. Trees, photos, measurements, site notes and voice notes are saved on the phone and upload when you are back in signal. Nothing is lost if you have no bars in the middle of a wood. Satellite maps need signal for now.

Can I override the category?

Always. Tree Atlas proposes A, B, C or U from a stated rule set and stamps the rule version on each tree. Your judgement is final, and the method is set out in the report appendix.

Who owns my data, and can I export it?

You do. Export the tree schedule as CSV at any time, and download your reports, plans and DXF files whenever you like.

Is my data kept in the UK or EU?

Your survey data, photos and reports are stored in the EU, in Ireland. A photo sent for a species suggestion and a voice note sent for transcription are processed by Google (Gemini on Vertex AI) in London, in the UK. The privacy policy lists every service we use.

How does the AI work, and can I turn it off?

AI suggests a species from your photo and transcribes voice notes. Both are optional. A suggestion is never saved until you confirm it, and transcription can be switched off.

How much does it cost?

Solo is £49 a month plus VAT (£58.80 including VAT) after a 30-day free trial. No card is needed to start. The pricing page has the details.

What happens after the trial?

If you don't subscribe, recording stops but nothing is deleted. Your trees stay on your account and CSV export stays free. No card is taken during the 30 days.

Will it cover the revised BS 5837?

A revision is expected, but its date is unconfirmed. Tree Atlas stamps the rule version on every tree and report, so a survey you sign today stays as it was issued when the standard changes.

Does it run on iPhone, iPad and Android?

iPhone and iPad from the App Store, and the web desk in any modern browser. On Android, use Tree Atlas in the browser for now: the Google Play app is coming soon.

What is a BS 5837 tree survey?

A survey of the trees on a site, recorded to BS 5837:2012. Each tree gets its species, measurements and condition, a category of A, B, C or U, and a root protection area. Tree Atlas records this on site and writes it up as the BS 5837 report.

What is a Tree Constraints Plan?

A plan of the site showing each surveyed tree with its BS 5837 category and root protection area, so the layout can be designed around the trees. Tree Atlas produces it from the same survey records as the report, as a PDF, with a DXF by category for CAD.
