How to set a stake-out peg with coordinate guidance and photos
Setting a stake-out peg is more than walking to a target on screen.
Field takeaways
- Target and staked point should be separate records.
- Tolerance must be defined before work.
- Check RTK and control before critical stake-out.
- Photos and notes defend the field mark.
- MapLab Survey organizes targets, staked points and reports.
Verify the target first
A stake-out point arrives from CSV, DXF or a hand-typed coordinate. If the coordinate system, point name or revision is wrong, you can set the stake perfectly and still have done the wrong job. Three questions before driving anything: which system is this list in, which revision, which points are current this week?
The setting flow in the field
Test the device on a known control point first — does the reading match the known value? Approach the target and read the deltas (forward/back, left/right). Inside tolerance, drive the stake; record the as-set point on its own "set" layer with coordinate and photo. Keeping the target list and the as-set list separate means the end-of-job comparison writes the report for you.
Honesty about tolerance
Phone-GPS stake-out suits metre-level work: rough site marking, preliminary layout, reconnaissance. Centimetre-tolerance work requires a Bluetooth RTK receiver — with a fixed solution the deltas stream at centimetre precision. Write which hardware set the stake into the report; whoever reads the tolerance must know the method too.
What the AR view adds
Live guided stake-out overlays arrow and distance on the camera image. On a crowded site, in vegetation or on long walks it keeps you from losing the direction. The last metres still come down to reading deltas — AR speeds the rough approach; it is not the source of precision.
After the stake is in
Keep the point name, as-set coordinate, deviation from target and photo in one record. The answer to "it was set — but where?" should be deliverable as one CSV or PDF when the job closes. The evidential weight of a stake-out report comes from this discipline.

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
Is RTK needed?
For precise construction, usually yes.
Target and staked point same record?
Better keep them separate.
What is tolerance?
Accepted difference from target.
Can MapLab Survey help reports?
Yes.
