The correction type may be one of the following:
-“WAAS”
- “RTCM”
- “Post-processed”
- “Uncorrected” (for autonomous positions)
• Accuracy Estimation for the selected point: horizontal
error, vertical error (non-editable).
• Offset data (editable): direction (for line or area) or bear-
ing (for point), horizontal distance, vertical distance.
This set of properties can be used to artificially move the
receiver’s GPS antenna by a certain distance from the real
position it occupied in the field.
For example, if the receiver was held at 5 feet (1.52 m)
from the ground, you can enter “-1.52” m in the vertical
distance cell to artificially bring the GPS antenna position
down to ground level.
Likewise, you can offset a line or area feature to the right
or left by a certain distance that you enter in the horizon-
tal distance cell. The Left and Right directions for the off-
set are defined with respect to the direction followed by
the field operator along the feature while logging this fea-
ture (see example opposite).
• Attributes (editable): list of attributes and values currently
assigned to these attributes. You can freely change these
values or enter new ones if blank.
There are many other functions that you can use in Mo-
bileMapper Office such as creating feature libraries or back-
ground maps, importing/exporting GIS data, downloading
reference station data, post-processing jobs, etc. Please refer
