Linked files

You can link CSV, TXT or job files so that you have access to the points in those files without adding them to the job (for example, a file containing control points). Data in linked files appears in the map.

You can use points from a linked file to:

  • stake out without having the design points in the job
  • enter values into Point name fields, such as for Cogo functions
  • navigate to control or check shots from previous surveys

When using points from linked files, make sure that they use the same coordinate system as the job that they are being brought into. The coordinate order (northing and easting ordinates) in the comma delimited file must be the same as the setting in the Coordinate order field in the Units screen. Make sure the data in the file is in the format: Point name, First ordinate (Northing or Easting), Second ordinate (Northing or Easting), Elevation, Point code.

Linked CSV points appear as a comma ( , ). Linked points from another job appear with their original point symbol. All linked points appear blue.

 

  • In a linked job, you cannot access lines, arcs, or polylines.
  • You can link multiple files. When the point does not exist in the current job, but does exist in multiple linked files, the point in the first linked file is used. If multiple points of the same name exist in a linked job, the search rules work within that job to find the best point.
  • You can only review points in a linked file from the map. Once you select a linked point and copy it into the current job, it appears as a "c" in the map.

To import points from a linked file to the current job, see To import data to the job.

  1. Tap and select Job. The current job is already selected.
  2. Tap Properties.
  3. Tap Linked files. The Linked files screen lists the files in the current project folder.

  4. Tap the file(s) that you want to link to the current job or tap All to select all files.

  5. To add files from another folder to the list, tap Add, navigate to the required folder and then select the file(s) to add.
  6. If the Advanced geodetic check box is enabled in the Cogo settings screen, and you select a CSV or TXT file, you must specify the Coordinate type of the points in the file. Select Grid points or Grid (local) points.
  7. If the points in the file are Grid (local) points, select the transformation to use to transform them to grid points:

    • To assign the transformation later, select Not applied, this will be defined later. Tap Accept.

      If you select this option and you later decide to assign an input transformation to this file, you must unlink and then relink the file.

    • To create a new display transformation, select Create new transformation. Tap Next and complete the required steps. See Transformations.
    • To select an existing display transformation, select Select transformation. Select the display transformation from the list. Tap Accept.

  8. Tap Accept.
