B Tip
You can also select a background file to display on the map. To display
a menu of files you can use as backgrounds, select the Background file
field. The menu includes all rover files on the TSC1 datalogger or PC
card, and background files that have been transferred from the GPS
Pathfinder Office software.
– A file stored on a PC card takes longer to open than a file stored in
the main memory of the TSC1 datalogger. This includes background files
as well as foreground data files. Move files you use frequently from the PC
card to the TSC1 to speed up opening.
If you select a background file, display the background by pressing
in the Map screen. When the background is enabled, this softkey
changes to2. Press it to hide the background. By default, the
background is displayed.
TheFsoftkeyintheMapdisplay options form lets you customize
the symbols (icons) used for different point features. You can assign
1
one of ten icons to any point feature type in the data dictionary, and the
same icon can be used for more than one feature. By default, the
software assigns symbols to point features to minimize the number of
features that share a symbol.
The\softkeyintheMapdisplay options form lets you customize
the attributes from each feature type that are used as labels. The values
of the two label attributes are displayed when a feature is selected. By
default, the attributes selected as labels are the first two attributes
added to the feature type in the data dictionary.
The^ softkey opens a menu of filter types and lets you select and
define filters, so only the features you want to see are displayed. The
same Filter by menu can be opened using the^softkeyinthe
Review data list. Information on applying filters can be found in the
section on File Operations, page 103.
