Stop-and-Go
Since the Stop-and-Go method requires an initialization, the
occupation times are much shorter than the static method.
Initialization on a known point can be accomplished in as lit-
tle as 15 seconds with a 1 second recording interval.
Initialization with the initializer bar is typically 5 minutes.
Stop-and-Go point occupations can be accomplished in as lit-
tle as 15 seconds with a 1 second recording interval.
These occupation times may vary depending upon the three
factors 1, 2 and 3 described above.
Kinematic
The Kinematic method also requires an initialization as de-
tailed in the Stop-and-Go method.
Kinematic data collection does not use an occupation timer
since kinematic data is collected while moving. The recording
interval must be set to a value that properly matches the
speed you are moving.
A recording interval set too slow may result in data that does
not represent the feature being surveyed. A recording interval
set too fast may result in data too dense for a particular appli
-
cation (This is also true in Static and Stop-and-Go).
The base and kinematic units must be set to the same record-
ing interval for successful kinematic survey.
Mobile Mapping
The ProMark3 needs 2 or 3 seconds to open a feature, record
at least one epoch and close the file successfully. So when you
open a point feature, please record for 2 or 3 seconds before
closing the feature. To improve accuracy of point features, we
recommend recording for 30 seconds - or even longer for op
-
timal accuracy.
