RapidStation Block File Format | Sections | 21
[gcp-weight-classes]*
Note
The section is mandatory if section [ground-control-points] is being introduced.
The values in this section are normally estimations on how accurate the GPS
measurements of the ground control points are. The following keywords are
possible in this section:
units = object-unit
The units can be any one of the units defined by the European Petroleum Survey
Group (EPSG) and listed in Appendix 1, and they relate to the output object
coordinate system defined in section [rapidstation-block]. The default value is metre.
columns = description-of-the-columns
“columns” keyword describes the contents of the tabular data either at the end of
this section or in an external file. The tags should be listed in the same order they
appear. The allowed column tags are:

ID: unique string or number identification of the weight class.

S_E: standard deviation of the easting coordinates.

S_N: standard deviation of the northing coordinates.

S_EN: standard deviation of the easting and northing coordinates.

S_H: standard deviation of the height coordinates.

S_X: standard deviation of the X coordinates.

S_Y: standard deviation of the Y coordinates.

S_XY: standard deviation of the X and Y coordinates.

S_Z: standard deviation of the Z coordinates.

SKIP: this column is to be skipped and ignored
Example:
columns= ID S_EN S_H
pos1 0.02 0.2
[adjusted-points]
The values in this section are normally output from bundle block adjustment. In
case of a close-range photogrammetric block this section will refer to X Y and Z
co-ordinates, else E(asting), N(orthing) and H(eight) are being used. The
following keywords are possible in this section:
coordinate-system = horizontal [vertical]*
Currently only the horizontal coordinate system is used and thus the vertical part can
be left out. The value should be the same as corresponding value in section
[rapidstation-block] referring to bundle block adjustment. The coordinate system
must be one of the ones defined in csystems.ini. See separate manual describing
csystems.ini.
