Appendix E Using the Target Utility
Target is a software module included with Isis. You use Target to take snapshots
of selective areas of your data imagery that may be of special interest to you.
When Target takes a snapshot of an image, Target also logs the quantitative
data (geocoding, contact mensuration) associated with the image. Thus the
image always has a context, a link back to the original data imagery from which
the image came.
You can then save these small images as files independent of the original data
imagery. You can then recall the image in Isis without having to play back the
entire data imagery that contained the selected image—or you can have Isis
playback the image in the larger context of your data imagery, in case you want
to see the area surrounding the selected image.
E.1 Running Target
You run Target in any of four ways, shown next. Choose a convenient method.
To run Target
• Double-click on the Target icon in the Triton group (Microsoft
Windows™),
or
• Choose
Target from the Isis Tools menu, or
• Double-click the left trackball button while imagery is scrolling in a
Waterfall window (clicking this way this also puts a contact in the
Target working window at the same time),
or
• In ROVFlight, select a displayed contact (selected contact is blue) and
click on the
Recall Object in Target button.
However you start Target, the system uses a default CFG file name of
TARGET{new_name}, where {new_name} is the name of the local computer.
This allows the program to be run from a single network directory to many
different workstations, each with its own configuration file.
E.2 Target’s File Menu
You use Target’s File menu (Figure E-1) to manage contact files. Table E-1 lists
the functions.
