Point code information and attributes
When a point is logged a number of different information is logged together with the point code and
coordinate. Below you can see a list of information with an explanation of the different values.
Point name:
A unique name used to identify
individual points
N:
The measured points northern coordinate. This
value is measured on the toolpoint
E:
The measured points eastern coordinate. This
value is measured on the toolpoint
H:
The measured points elevation. This value is
measured on the toolpoint
VRMS:
Shows the vertical accuracy of the GNSS
when the point was logged. Accuracy is defined on
the GNSS antenna, not the toolpoint
HRMS:
Shows the horizontal accuracy of the
GNSS when the point was logged. Accuracy is
defined on the GNSS antenna, not the toolpoint
Mount point:
Shows which mount point was
chosen for the connected NTRIP server
Project offset:
If a application has an project offset
entered to adjust toolpoint elevation to match the
elevation of an known point on the construction site
ExtSurf:
Showing if the point measured is done on
an extended surface value can be 0(no) or 1(Yes)
ToolHeight:
Shows the height offset applied to the
measured toolpoint eg. Pole height for stakeout, or
Tablet height for PerFormans
Time:
The time where the point was logged logged
in a YYYY-mm-dd HH:MM:ss format Example:
2022-02-15 09:43:34
systemName:
Shows the name of the system that
logged the point. This system name matches the
system name on the Cloud
PDOP:
Dilution Of Precision, indicates how errors
in measurement will affect the absolute position
calculation. Dop can be calculated in different
variants. (HDOP, VDOP, PDOP, TDOP, GDOP)
The DOP value logged in the as-build data is the
PDOP value. (Position dilution of precision) This
can be considered as the 3D DOP. The value is
relative and not related to a specific measurement
unit.
Sats:
Showing how many satellites was visible
when the point was logged. The value is the sum of
satellites, and not divided into specific satellite
constellations (GPS, Glonass, Beidou, Galileo)
CQ:
Coordinate Quality. Shows the calculated
accuracy of the GNSS antenna position when the
point was logged. This is not a definition for the
accuracy of the toolpoint position which is
measured. Value shows accuracy in meters
SiderefFile:
Side reference file. Shows the name
of the file used as active side reference when point
was logged
LogOffset:
Delta height. Shows if the operator has
added an offset to the logged point. Often used if it
is impossible to log the exact position due to limited
space. Eg logging the inlet in a manhole. Then the
operator can log a point on the top of the manhole,
measure the distance from the measured point to
the inlet, and enter this as a delta height
SiderefName:
Side reference name. Shows the
name of the specific reference inside the reference
file, used as active side reference when point was
logged
App:
Shows which system has logged this specific
point.
Sidedist:
Shows the horizontal distance from
toolpoint to side reference when point was logged
