Additional calculation method for the geometric ppm value
The geometric ppm value can also be calculated by a resection calculation. The
scale factor from the resection is used for PPM.
Individual ppm=(s-1)*106.s=1+ppm*10
lated with the following:
Scale at CM: 1,
•
Offset to CM: 0,
•
Map projection ppm: 0 and
•
• Ground height: 0.

Option Description
Editable The user-entered scale factor.
field Compute scale from: User entered scale fac-
tor.
Editable The individual ppm value.
field Available for Compute scale from: Projection &
height info and Compute scale from: User
entered ppm.
Display The map projection ppm value. If this value cannot
only be calculated, then ----- is displayed and is also
ignored in the calculation of the geometric ppm
value.
Available for Compute scale from: Projection &
height info and Compute scale from: Current
setup.
Display The height ppm value calculated from the height
only coordinates of the current setup stored in the
internal memory. If this value cannot be calcula-
ted, then ----- is displayed and is also ignored in
the calculation of the geometric ppm value.
Available for Compute scale from: Projection &
height info and Compute scale from: Current
setup.
Display For Projection & height info:
only Geometric ppm =
Map projection ppm + PPM + height ppm value
calculated fromGround height.
For Current setup:
Geometric ppm =
Map projection ppm + Height ppm.
Editable The scale at the central meridian.
field Available for Compute scale from: Projection &
height info.
Editable The offset to the central meridian.
field Available for Compute scale from: Projection &
height info.
Editable The height of the instrument setup above the ref-
field erence datum.
Available for Compute scale from: Projection &
