Examples of station coordinate files

Example 1: Geodetic coordinates with geoid information

The following example shows the beginning of a station coordinate file containing coordinates in a geodetic (latitude and longitude) coordinate system, in this case NZGD49. The file lists the deflections and geoid undulation of each station. The data do not need to be aligned in columns, though the file is more readable if they are. The comment line start !Code is not required. No options are specified, so the default options of deflections and geoid_heights apply.

Example 2: Projection coordinates

The following example shows a station coordinate file containing projection coordinates. The projection is defined by the code BLUF on the second line. This is defined in the COORDSYS.DEF file as a Transverse Mercator projection based upon NZGD49. In this case the deflections and undulation are not included. This is specified in the options line.

Example 3: Projection coordinates, geoid heights, and station orders

This example of a station file includes ellipsoidal heights with geoid heights. Also it includes a column of station orders that can be used to select stations in the adjustment, and a column of mark types.
