Position of <Name> dialog

This dialog appears if you do one of the following:

• Provide station information to the system.
  1. This is possible in several ways, for example, when editing the System Properties. A dialog allowing you to view or edit station information appears such as, for example, the Station Information dialog.
  2. Select a station from the list and expand its Position category.
  3. Set the focus on any of the coordinate or velocity values and click the browse button.

• Provide point information to a system providing terrestrial data.
  1. This is possible in several ways, for example, when editing the System Properties. A dialog allowing you to view or edit point information appears such as, for example, the Point Information dialog.
  2. Select a point from the list and set the Enable global coordinates property to Yes.
  3. Set the focus on any of the coordinate or velocity values and click the browse button.

Use the Position of <Station name / Point name> dialog to manually edit the reference coordinates of the station or point (global coordinate) and the yearly velocities of station / point movements due to tectonic, not plate-related motion.

Coordinate System setting

Use the Coordinate system drop-down field to select the coordinate system for the reference coordinates. Coordinates can be edited and displayed either as Cartesian (default) or as geographical coordinates, all referring to a tectonic plate and a reference time. To view and edit the tectonic plate and the reference time, return to the previous dialog.

Coordinate settings Latitude, Longitude, Height or X , Y , Z

Coordinates appear either as geographical latitude, longitude, height or as Cartesian X,Y,Z coordinates. Use the fields for manually editing the reference position. X,Y,Z and height coordinates are in meters with a precision of four decimals; latitude and longitude allow the input of degrees, minutes, and seconds, the latter with 5 decimals.

Velocities X , Y , Z settings

Known velocities of movement (independent of the tectonic plate) in X-, Y-, and Z-direction with respect to the known position determined at a specific date. The unit is meters per year with 6 decimals. Default values are 0.000000 m/year.

Pasting coordinate values

Pasting copied coordinates from the Windows clipboard into the fields is a one-step task if you mind the following:

• Make sure the coordinates are provided in the order X, Y, Z or Latitude, Longitude, Height (for example, 4000000.0000 800000.0000 4000000.0000).
• Make sure the coordinates are separated by an arbitrary number of spaces, tabs, or semicolons (commas and dots are not allowed as separators).
• Make sure the matching coordinate system is selected.
• Select any field and paste the string containing the three coordinate values into this field.

Trimble 4D Control Server automatically allocates each coordinate value to its matching entry field.
