Log message: geography/gama: Update to 2.22 This is a bug fix release. New gama-local adjustment XML output definition gama-local-adjustment.xsd version 1.02. New XML tag <not-applicable/> was added to the adjustment ouput format for cases with zero degrees of freedom, where the standard deviation test is not applicable (previously there were only two tags <passed/> and <failed/>). Old XML output files are formally complient with the new XSD version 1.02 |

Log message:
geography/gama: Update to 1.21
Changes in release 2.21
- bugfixes
Changes in release 2.20 (2022-06-30)
- The new algorithm ICGS (iterated classical Gram-Schmidt) in the
class AdjGSO replaced the former algorithm MGS (modified
Gram-Schmidt), which was implemented with column pivoting as a
template class GSO. The template class GSO is meant only as a tool
for testing purposes. Both initial scaling and pivoting with
euclidean norms are not suitable for practical computations.
The old legacy code with MGS used in the AdjGSO class is still
available with conditional compilation directive statements if the
name GNU_GAMA_GSO_LEGACY_CODE is defined.

Log message: geography/gama: Update to 2.18 * Changes in release 2.18 (2022-04-09) New conversion class K2gkf (lib/krumm) with accompanying program krumm2gama-local and the testing suite for converting input data format used in the text book "Geodetic Network Adjustment Examples" by Friedhelm Krumm, Geodätisches Institut Universität Stuttgart, 2020. Not all input data in Krumm Format can be converted to GNU Gama, i.e. to the adjustment program gama-local input XML: * scale factor is not implemented in gama-local adjustment * gama-local does not enable fixing only x coordinate (or y coordinate) for 2D free network to remove singularity. This kind of regularization has very little practical meaning. Technically it would be possible to enable this feature in gama-local, but it is questionable if the outcome would not enable more confusion than possible outcome. Adustment should not be dependent on the coordinate system used. * gama-local does not deduce that an azimuth to the unknown point P can be combined with some angle pointing to the P to create a new feigned azimuth. This is an interesting feature which may be implemented in some future version, namely in the gama-local stage of computing approximate coordinates. * nonlinear conditions are not implemented in gama-local * BLH coordinates are not supported in gama-local |
