[Info-gama] with regard to azimuth tag |

Dear GNU Gama professionals,
I would like to use new azimuth feature, trying to combine masurements made
with theodolith and laser distance meter or with compass, miner's level and
laser distance meter.
I compiled GNU Gama 1.14 with mingw on windows xp.
Now it seems to me that GNU Gama simply ignores the azimut values.
For all points defined by azimuth values instead of directions GNU Gama's seems
to ignore the input.
Trying the appended Azimut_Test1.gkf - Intended as an equilateral triangle with
two fixed points "1" an "2" and one new point ("3"-"9") measured in differend
ways - I will get "Missing coordinates" in the output.
May be I have a wrong understanding of the concept behind the azimuth
implementation?
In the manual I find "<azimuth from="1" to= "2" val= "96.484371" />" as an
example. The "from =" part is not accepted by the software.
I find the File "gama-local.dtd" in \gama-1-14\xml\ defines no "from ="
<!ATTLIST azimuth
to CDATA #REQUIRED
val NMTOKEN #REQUIRED
stdev NMTOKEN #IMPLIED
from_dh NMTOKEN #IMPLIED
to_dh NMTOKEN #IMPLIED >
so the azimuth statement is to be nested in an "obs from =" statement?
In the manual page 12 in the PDF version I read
" The value of an orientation angle can be explicitly stated with an attribute
orientation="...". Normally, it is more convenient to let the program calculate
approximate values of orientations needed for the adjustment. If directions are
present, then the attribute station must be defined. "
Am I right in thinking that "orientation" is not the same as azimuth?
Orientation may be used finding approximate coordinates and directions as
starting point and azimuths are used only in the adjustment?
Is the mentioned "attribute station" to alter in the "from =" part of "obs"
like in the examples?
Thank you in advance for any further information.
Dirk
