Hi Michael,
Look at the attached file. In ArcGis 10.3.1 you have to select a geographic
transformation before you start a transformation between two datums.
It seems that the transformation in CTS does not need such a information?
And if i want to transform from MGI (Austria) to
D_Deutsches_Hauptdreiecksnetz(Germany)? Does this run automatically too?
Transformation from MGI to WGS 84 and after that transformation from WGS84 to
D_Deutsches_Hauptdreiecksnetz?
Best regards,
Manfred
Hi Manfred,
What do you mean exactly ?
In CTS, one performs transformations between two CRS (Coordinate
Reference System)
A CRS uses a specific datum, ellipsoid, prime meridian, and in case of a
projected CRS, projection.
With all these informations, it can compute transformations from/to
WGS84 (geographic or cartesian).
What do you mean by geographic transformation ? How do you define WGS84
to MGI(Austria) transformation in other softwares ?
Note that all parameters used by cts are in the epsg file (which is the
same as the one used by proj4).
Micha?l
