7. Gama-local companion tools
With gama-local come several companion command line tools, most
of them being conversion programs for various data formats.
7.1 gama-local-deformation
Program gama-local-deformation reads XML adjustment results files from
two dates (epochs), compute differences for adjusted points common in
both epochs, calculate the covariance matrix of the differences and
optionally renders the deformation diagram in SVG output file.
| |
Usage: gama-local-deformation epoch1.xml epoch2.xml [--text file] [--svg file]
gama-local-deformation --version
gama-local-deformation --help
Options:
epoch1 and epoch2 are adjustment results in XML format of the surveying network.
The program computes the shift vectors of common adjusted points
and their corresponding covariance matrix.
--text deformation analyses in textual format. If missing, standard
output device is used (i.e. screen).
--svg if defined, the program writes SVG image of the second epoch
adjustment with standard deviation ellipses and points' shits.
The network schema is available only in 2D (xy coordinates only).

7.2 gama-local-gkf2yaml
Program gama-local-gkf2yaml converts input XML format of
gama-local (in Gama project usually denoted with
extension gkf) to yaml format.
| |
gama-local-gkf2yaml input.gkf [output.yaml]
|
7.3 gama-local-yaml2gkf
Program gama-local-yaml2gkf converts YAML input to XML imput format.
| |
gama-local-yaml2gkf input.yaml [ output.gkf ]
|
7.4 gama-local-xml2sql
Program gama-local-xml2sql converts gama-local XML input format (aka gkf) to SQL script.
| | Usage: gama-local-xml2sql configuration (xml_input|-) [sql_output|-]
Convert XML adjustment input of gama-local to SQL
|
7.5 gama-local-xml2txt
Conversion from adjustment XML output to text format.
| |
Usage: gama-local-xml2txt [options] < std_input > std_output
Convert XML adjustment output of gama-local to text format
Options:
--angles 400 | 360
--language en | ca | cz | du | fi | fr | hu | ru | ua
--encoding utf-8 | iso-8859-2 | iso-8859-2-flat | cp-1250 | cp-1251

7.6 krumm2gama-local
GNU Gama sources come with an extensive set of testing data examples
in the directory tests where subdirectory tests/krumm
contains examples from the book by Friedhelm Krumm, Geodetic Network
Adjustment Examples, Geodätisches Institut Universität Stuttgart,
https://www.gis.uni-stuttgart.de, Rev. 3.5 January 20, 2020. All these
examples are distributed with GNU Gama with permission from the author.
Conversion program krumm2gama-local converts the examples data
format defined in the book to the gama-local XML input
format. For more details read the file
tests/krumm/input.README.md.

Conversion from data format used in Geodetic Network Adjustment Examples
by Friedhelm Krumm to XML input format of gama-local (GNU Gama)
https://www.gis.uni-stuttgart.de/lehre/campus-docs/adjustment_examples.pdf
krumm2gama-local input_file [ output_file ]
krumm2gama-local < std_input [ > std_output ]
Options:
-h, --help this text
-v, --version print program version
-e, --examples add the following comment to the generated XML file
This example is based on published material Geodetic Network Adjustment
Examples by Friedhelm Krumm, Geodätisches Institut Universität Stuttgart,
