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.
Before the first peg
Check a known point and confirm the coordinate system. A misplaced peg becomes a misplaced wall, and no app repairs that.
During stake-out
Approach using distance and bearing guidance until you are inside the agreed tolerance. Do not settle for "about here" when the specification asks for centimetres.
After driving it
Photograph the peg with its surroundings, note the deviation from the design value and store everything in the same project. That record is what defends you in the later discussion.
Protect it from the machines
Pegs in the path of plant do not survive a day. Mark them visibly, or offset the point to a protected position and record the offset so the original can be restored.

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.
