Version 1.15 February 2014
* DTD replaced with XSD for gama-local.xsd and
gama-local-adjustment.xsd. Attribute version describing XML version
of input and adjustment outpup XML documents became useles with
introduction of XSD a was removed from tags <gama-local> and
<gama-local-adjustment>. Some more elements attributes were
introduced in revised XML formats which are incompatible with older
versions.
Version 1.14 June 2013
* A posteriori standard deviation Chi-Square test is newly always
performed (even when gama-local uses a priori reference standard
deviation).
* Added Chinese translation in GBK encoding (switch "zh")
* New output format XHTML Strict 1.0 in gama-local
* Added a basic test suite for gama-local (make check).
Version 1.13
* Fixed templates lookup name syntax errors reported by Brandon
Invergo <brandon@invergo.net> (detected by compiler g++-4.7).
Many thanks for your patch, Brandon.
* Fixed a bug reported by Jacques Beilin <jacques.beilin@ensg.eu>
Function NormalDistribution ended in an endless loop for high
values of input argument x.
* Fixed a bug reported by Anton Horpynich <anton@vingeo.com>
The computation of approximate coordinates failed if an angle
needed for computing of an intersection was smaller than 0.15
radians / 10 gons (implicit testing criterion). Although this is a
reasonable limit for standard surveying networks, in a batch
computation of approximate coordinates a much smaller value can be
sometimes acceptable. It is more or less a matter of personal
opinion if this is to be supposed a bug or not.
Gama newly solves approximate coordinates in two main loops.
During the first loop the default value 0.15 in class Acord is
used. If afterwards there still some coordinates remain
missing, Gama starts a second loop with series of iterations in
which firstly tries to find a solution with the default value
then secondly with a very tiny limit of 0.0015 radians.
In most cases all coordinates are solved in the first loop with
the default small angle limit 10 gons.
* In gama-local suppressed output of running results during
linearization iterations and several other minor fixes
Version 1.12
* class BaseVisitor and related classes moved to separete file visitor.h
* local Observation has protected init method and non-parametric constructor
Code in local Observation was reorganized and some atributes are not const.
* local observations are visitable (base is Accept<>)
- class Direction : public Observation
+ class Direction : public Accept<Direction, Observation>
** local observations' write methods moved to WriteVisitor
** LocalRevision and LocalLinearization are now visitors
** base classes Revision and Linearization removed from local
** method observations_summary in LocalNetworkXML uses visitor for counting
** method observations in LocalNetworkXML uses visitor for writing
** function OutlyingAbsoluteTerms uses visitor for writing
** method test_abs_term in LocalNetwork uses visitor for test
** local Observation set_passive and set_active methods are now non-const
** function AdjustedObservations uses visitor for writing part of table row
** function TestLinearization uses visitor for computing and writing
** function ResidualsObservations uses visitor writing observation name
* fixed a bug in the definition of angular observations reported
by Anna Kratochvilova <anna.kratochvilova@fsv.cvut.cz> and Vaclav
Petras <vaclav.petras@fsv.cvut.cz>
* updated version of review.hu.lang by Siki Zoltan, some
corrections in the Hungarian translation of GNU Gama
Upstream says that using sqlite3 will become somewhere between normal
and the standard approach. Because sqlite3 is small and typically
already isntalled on systems where one would want to run gama, just
depend on it and don't bother to make it an option.
It would be fine with me to make it a default-on option, but I don't
think that's worth the complexity.
GNU Gama is a project dedicated to adjustment of geodetic networks. It
is intended for use with traditional geodetic surveyings which are
still used and needed in special measurements (e.g., underground or
high precision engineering measurements) where the Global Positioning
System (GPS) cannot be used.
Adjustment in local Cartesian coordinate systems is fully supported by
a command-line program gama-local that adjusts geodetic (free)
networks of observed distances, directions, angles, height
differences, 3D vectors and observed coordinates (coordinates with
given variance-covariance matrix). Adjustment in global coordinate
systems is supported only partly as a gama-g3 program.
