Stake-out: carrying design coordinates safely to the ground
Surveying brings the ground into the project. Stake-out brings the project back to the ground. The CAD point becomes a stake, paint mark, nail or machine-readable mark on site.
Field takeaways
- Stake-out means reaching the design coordinate within tolerance.
- Use delta E/N or forward/back/left/right guidance; a phone compass alone is not enough for precise work.
- Do not set critical points before checking control and CRS.
- RTK is fast under open sky; total station can be stronger in obstructed or indoor sites.
- Mark, photograph and report the staked point.
Stake-out is surveying in reverse
In surveying you find the coordinate of an unknown point; in stake-out you find a known coordinate on the ground. The error sources run backwards too: the design file, the coordinate system, the control point, the navigation and the physical mark all have to be right together — one weak link moves the peg.
Tolerance is the language of the job
A garden fence, a building axis, a machine anchor bolt and a road level do not share a tolerance. Get the horizontal and vertical tolerances in writing before going out. The word "approximately" produces arguments on site; a figure like "±2 cm horizontal, ±1 cm vertical" produces decisions.
Staking with RTK
Under open sky RTK is fast: the delta E/N values shrink as you approach, and the point is marked once inside tolerance. But beside buildings, under trees, around cranes and among dense metal, multipath grows. In such spots, do not press on unchecked even when the screen says fixed.
Staking with a total station
Where a line of sight can be established, the total station is highly controlled. Indoors, in tunnels, on facades and under an obstructed sky it is often more reliable than GNSS. Large jobs use both: GNSS establishes the broad control, the total station drives the precise detail.
The record that outlives the peg
Import the design points into MapLab Survey, verify the project coordinate system, and test on a control point. Leave a photo, note, date and tolerance for every staked point. The value of a stake-out is not only the peg in the ground — it is the answer, months later, to "which point was set, according to what?"

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
What is stake-out?
Marking a design coordinate on the ground within tolerance.
Is RTK enough?
Under open sky with control checks it can be; obstructed sites may need total station.
What is delta E/N?
The east/north difference from your current position to the target.
What should a report include?
Point name, coordinate, date, crew, tolerance, method, photo and control note.
