Separation: Enter the separation between the inclined plane and the local elevation.
Origin N / E: Enter the local origin (north,east) of the inclined plane.
[Solve >]: Updates the calibration solution using the values entered on the Horizontal and/or Vertical cards.
Calibration calculator
The Calibration Calculator screen is used to setup a calibration parallel to a selected mapping plane zone, or some
arbitrary rotation, from a single control point.
Rotation: Enter the rotation angle used for the calibration. This angle should be the negative of the meridian
convergence from your desired grid origin the default ground calibration zone. You can use the [Calc Rotation]
function to set the calibration to be parallel to a mapping plane zone. Alternatively, if you have some other origin for
the grid directions, such as a sun shot or the central meridian of a township, you can enter the convergence between
that location and the origin of the default ground calibration zone.
[Calc Rotation]: Opens the
screen in calculate rotation mode. The results are filled into the
Rotation field when you complete the calculation.
Base Station Local Coordinate: Enter the local plane coordinates of the base. If you set up on a new base point, these
fields are blank and you need to occupy one control point to calculate the base station local coordinates.
[Occupy Control]: Opens the
screen where you select a control point to occupy. When you are done,
the base local coordinate is calculated using your entered rotation.
Projection – Mapping Plane Mode
The Projection screen is described here for when the horizontal projection mode is set to Mapping Plane. Use this
setting when you want your coordinate system to be a conformal map projection chosen from the coordinate system
database file.
Status Line: The text at the top of the screen describes the status of the horizontal projection solution.
[Show Details…]: Opens the
screen, where the complete details of the calibration solution,
reference map projection, and Geoid model are displayed.
screen where you can choose a zone or site from the data base,
key in a custom zone, and delete zones or sites from the database.
[Mapping Plane Ground…]: Opens the
screen where the grid to ground conversion parameters
can be calculated and applied.
[Solve Calibration…]: Opens the
screen where control points can be selected and the horizontal
and vertical calibration are solved.
[Switch to Default Ground Calibration…]: Switches the horizontal projection mode from Mapping Plane mode to
Ground Default Ground Calibration mode
Select Coordinate System
The Select Coordinate System screen is used to choose a mapping plane zone or localized site from the coordinate
system database file. You can also open the
wizard to create a new zone and datum with user specified
