Towfish
Towfish attitude information for the ping associated with
the center of the contact. This information is used by Isis
in geocoding and contact mensuration.
Cursor
The last requested cursor position within the contact
image. A cursor position is requested by clicking with the
left trackball button. If navigation data have been
transmitted to Isis as latitude and longitude, the button in
the upper left corner of this box provides a three-way
toggle for displaying position in decimal degrees,
degrees and decimal minutes, or degrees, minutes and
decimal seconds. Also included in the cursor box is the
contact classification (meaning class or type) if one has
been specified and the chord or distance between any
two points in two different contact images.
Contact Measure
When a contact is transferred from Isis to Target, the
position of the contact is given in the Contact Measure
box. This position is modified whenever the contact is
measured or when the measurement is modified. (See
‘Contact Mensuration’.)
Contact Position
This is the position of the contact if you mensurate it.
See the discussion in the section ‘Contact
Mensuration’.
