9. Tools¶

There are several tools available in the graphical user interface Tools menu, such as:

9.1. Sight Matrix to Obs¶

This tool is available via Tools > Sight Matrix to Obs. It converts a sight matrix into a simulated .obs file.

The sight matrix is given as a text file having on the first line the targets names and on the first column the stations names.

Example of matrix file:

X  T1 T2 T3 T4 S1
S1  1  0  0  1  0
S2  1  1  1  0  1
S3  0  0  1  0  0
S4  1  1  0  0  1

Note

1 means that there is intervisibility between the given station and target; hence, three observations will be created into the output .obs file (horizontal angle, vertical angle and distance, see Simple Observations).

In this example, there is intervisibility between station S1 and targets T1 and T4, which will create six observations from S1 in the output .obs file, intervisibility between station S2 and targets T1, T2, T3 and station S1 and so on.

9.2. Infinity ASC to BAS¶

Infinity ASC to BAS tool converts an .asc file, output of Leica Infinity software, into a Comp3D GNSS Baselines .bas file.

A .bas file is generated for each baselines’ starting point from the .asc file.

If the input .asc file contains heights values, it means that these heights were taken into account when computing the baseline. Therefore, the tool adds the heights as comments and with 0 values in the output .bas file.

9.3. Export Coordinates¶

The initial or compensated coordinates can be exported in geographic (decimal degrees or DMS) or cartesian (geocentric or project global) frames using the tool available in Tools > Export Coordinates.

9.4. Export to Cor¶

Export to Cor tool allows for the transformation of the initial or compensated coordinates into a .cor file.

Warning

As the adjusted coordinates of constrained points have variations due to least squares adjustment, it is mandatory to provide their original values in the .cor file.

9.5. Export Sight Matrix¶

In order to export the sight matrix of a project it is necessary to provide the .comp file of the project when using the tool available in Tools > Export Sight Matrix. The matrix is then exported as a .csv. file, to be used with Sight Matrix to Obs.

9.6. Export Variance-Covariance Matrix¶

After Normal Matrix Inversion, the variance-covariance matrix can be exported as a .comp_var_covar.csv file via Tools > Export Sight Matrix. This matrix is not affected by the value of final \(\sigma_0\).

Each line and column of the output file starts with the name of the corresponding parameter.

9.7. Export Sinex¶

If the computation used a georeferenced projection, it is possible to export a subset of points to sinex format by using Tools > Export Sinex.

All metadata provided in the form are saved into the .comp file of the project for all future exports.

9.8. Export Relative Precision¶

After computation, the relative precision between a set of points can be exported using Tools > Export Relative Precision.

9.9. Export Parameters Variations¶

Export Parameters Variations tool provides the possibility to export the variations of each parameter at each iteration after a compensation. It may be useful for debugging purposes.

9.10. Apply Cartesian Transfo¶

This tool reads a cartesian transformation from a .xyz file (see Subframes Files) and applies it to a cartesian coordinates file.

It is then possible to transform several point clouds from instrument frame (local frame) into project frame (global cartesian frame).

9.11. Cartesian from/to Projection¶

Cartesian From/To Projection tool allows for the transformation between projected (local or georeferenced) coordinates and global cartesian coordinates.

9.12. Project File Template¶

This tool retrieves all the necessary files for the html report. It also writes a minimal .comp file to create computation configurations outside Comp3D.
