Field point marking with stake, paint, nail, photo and coordinate record
Marking a point brings a map target into the physical field. The mark, coordinate and photo should be recorded.
Field takeaways
- Target and marked point should be recorded separately.
- Stake, paint, nail or tape should be photographed.
- Point names should describe the work.
- Precision work needs RTK and control checks.
- MapLab Survey connects marking records to reports and exports.
The job decides the marker
Paint is enough for a day, a wooden peg lasts a few weeks, a nail or a permanent marker is for control points. Choose wrong and you will measure the point again when the mark disappears — and re-measuring costs more than the most expensive marker ever did.
The record is the real mark
Every physical mark eventually goes; a point stored with its coordinate can be restored. That is why the point name, the target coordinate, the coordinate actually marked, the marker type, the date, the crew and the photo belong in one record. "Stake driven" in a notebook tells nobody anything six months later.
The field flow in MapLab Survey
Enter the targets by hand or import them from CSV or KML, walk in with live stake-out guidance — with AR overlay where it helps — and check the accuracy status before you commit. Leave the stake, paint or nail, then photograph it and add a short note. Recording the difference between the target and the marked point is what gives the stake-out record its evidential weight.
Photograph context, label the peg
Photograph the mark with something recognisable around it; a close-up of bare soil helps nobody months later. Write the point code on the peg in a visible colour — unnumbered pegs look identical after a week, and guessing which is which is how errors reach the concrete.
Honest about accuracy
Marking with phone GPS works at metre level, which suits reconnaissance and rough guidance. Construction axes, boundaries and formal stake-out demand centimetres: an external RTK receiver, a defined tolerance and a check on a known control point. Official boundary marking is licensed surveying work — the app speeds up the field side, it does not replace the signature.
One file at the end of the day
Targets, marked coordinates, deviations and photos should end the day as a single deliverable. Exporting a PDF report or a CSV from the same project puts the answer to "it was staked, but where?" into the archive.

MapLab Survey handles RTK/GNSS point capture, drawing, area and volume calculations and coordinate conversion, then exports to DXF, KML/KMZ, GeoJSON, Shapefile, GeoPackage, NCZ or CSV. Capture, calculation and export work offline. Live NTRIP corrections and online basemaps need a connection.
Frequently asked questions
How is a field point marked?
Navigate, place a mark, photograph and record notes.
Can phone GPS be used?
For reconnaissance, not precision stake-out.
Why photograph the stake?
For evidence.
Can MapLab Survey keep stakeout records?
Yes.
