Local Site Setting Options

Use these options to project grid coordinates onto locally surveyed ground coordinates so that grid distance matches ground distance. They are available in the Local Site Settings command pane.

Options

Project location

Coordinate type

Grid - Select this to enter the origin northing, easting, elevation, and height values in a grid system to apply this local scale and enter the elevation to compute the height scale factor.

Local - Select this to enter ellipsoidal latitude, longitude, and height on a local datum.

Global - Select this to enter global, ellipsoidal longitude and height on a global datum.

Ground coordinates

Use ground coordinates

Check this to enable the Ground scale factor box.

Ground scale factor

Type a factor by which to convert grid distances to ground distances.

Compute ground scale factor from project location

Check this to have the ground scale factor calculated for you. The value will be a product of the grid factor (determined from the horizontal project location) and the height scale factor (determined from the vertical project location).

Note: When Compute ground scale factor is checked, the Ground scale factor box is unavailable.

Coordinate Display

False Northing offset False Easting offset/

Type a value for the distance to offset from the northing and easting values.

For example, if you enter:

  • False northing offset:
    -6,540,000
  • Then a northing of 6,542,111 becomes:
    2,111
