logging. “Status” refers to the position computation mode
used at that time.
Also, using “Length” allows the program to automatically
assign the length of a line as one of its attributes. The length
of the line is computed as you walk along the line. The result
of the computation only appears after you have stopped
logging the line, when you review all its attributes. The same
is true with the “Perimeter” and “Area” attributes for a
polygon.
Adding attributes to a layer:
• From the Attributes tab of the layer properties window, tap
the Add... button.
• Enter a name for the attribute using the virtual keyboard.
• Select a type for this attribute.
• If this attribute will be a mandatory one to describe the
logged features, enable “Mandatory”.
• If applicable, set the additional one or two parameters.
• Tap on the Add button. This takes you back to the
Attributes tab where is now listed the attribute you have
just created.
• Resume the previous six steps until all the attributes have
been created.
Label
This setting is used to select the label you want to see on the
map screen, next to the features collected through that layer.
The label can only be one of the attribute values pertaining to
the feature. Choosing “None” means there won’t be any label
displayed.
Scale
This setting is used to display or hide the layer on the map
screen, depending on the current scale value used. The scale
property of the layer operates as a threshold, which will order
the layer to be hidden if the scale value on the map screen is
less than this threshold.

Features on the
Map Screen
• Tap Menu>Layers...

name to respectively show or hide the layer on the map

logged in that layer.
