AR stakeout: using a live view without losing coordinate discipline
A camera overlay can make point finding more intuitive, while the underlying survey still depends on positioning quality.

Page 4 of 5A GNSS stakeout workflow from design to as-built check
Reliable stakeout begins with the design reference and ends with a recorded check of the placed point.
Read articleTopographic GNSS surveys: collecting more than isolated points
A useful terrain dataset needs consistent positioning, feature descriptions and appropriate coverage.
Read articleGround control points vs checkpoints for drone mapping
Control helps a model fit; independent checkpoints help evaluate the result.
Read articleGNSS for agricultural mapping and field reference points
Agricultural mapping benefits from consistent references across boundaries, imagery and field observations.
Read articleGNSS corridor surveys: controlling a long, changing work area
Road, utility and linear-infrastructure work can cross changing reception and reference conditions.
Read articleRepeat observations: creating a stronger GNSS check
Two observations are more useful when they can expose different errors, rather than repeating the same setup unchanged.
Read articleA practical GNSS field checklist before recording points
A short, repeatable setup check can prevent errors that are difficult to repair in the office.

RINEX: what a receiver-independent GNSS file contains
RINEX exchanges GNSS observations and navigation information; it is not simply a list of final survey coordinates.
Read articlePreparing GNSS data for PPK processing
Post-processing needs compatible rover and reference observations that overlap in time.
Read articleExporting GNSS data to GIS without losing its meaning
A clean coordinate export must preserve references, units, identifiers and feature attributes.
Read articleAccuracy, precision and uncertainty in GNSS reports
Close agreement between repeated coordinates is useful, but it does not prove agreement with the intended reference.
