• Define each attribute for the point (see Entering Values for

Attributes on page 28).

•Tap OK to return to the map screen, which now shows the

location of the point according to the representation

defined in the layer properties.

Logging a Line or

Polygon Feature

• Stand at the beginning of the line or polygon you want to

log.

•Tap Log (or press the “–” key underneath). A menu

appears listing all the layers in the job.

• Tap on the desired layer name (“Lines” or “Areas” in our

example).

• Tap on the Settings tab and check or change the vertex

logging mode. As the last chosen mode is prompted by

default, you may not have to view this tab every time you

log a new line or polygon feature. Choose one of the

options below:

– Automatic: Selecting this option means the receiver will

automatically log points along the line or polygon at

regular intervals of time or distance. Enter the desired

value for this interval, either in seconds or meters.

– Manual: Selecting the option means you are only

interested in logging the vertices of the line or polygon,

and not points regularly distributed along the feature.

Enter the position averaging time, in seconds, that you

wish to spend on each vertex.

• To log the line or polygon with an offset, tap on the Offset

tab (otherwise skip this step) and enter the following

parameters (for no offset, just check that the horizontal

distance is 0 on this tab and proceed to the next step):

– Direction: this parameter tells the program whether the

real feature is on your left or right.

– Horizontal Distance field: Horizontal distance

perpendicular to the line or polygon feature.

If a range finder is used to measure this distance, tap

on the Read Range Finder button once the range finder

has got a valid measurement. This will automatically

fill in the field.

If no range finder is used, type an estimate of the

horizontal distance directly in the field using the

keyboard. The better you estimate the distance, the

better the collected positions.

•Tap OK. MobileMapper Field instantly starts logging the

feature.
