You can define how to transform data in the UTM coordinate system into data of a Gauss-Krüger coordinate system. You can see the current assignment. The log file lists the source system, destination system, and NTv2 grid file.

The UTM system is a global coordinate system that divides the surface of Earth between 80°S and 84°N latitude into 60 zones, each 6° of longitude in width. These individual zones are covered with a two-dimensional Cartesian coordinate system.

UTM is a worldwide standard that is used for surveying, GPS navigation, conventional maps, Google Earth and Google Maps. The UTM coordinate system has already replaced various national coordinate systems like the Gauss-Krüger system in Germany or the Swissgrid in Switzerland.

Allplan handles UTM, Gauss-Krüger and Swissgrid in the same way, that is as offset coordinates. It is usually not necessary to convert UTM coordinates to other coordinate systems such as Gauss-Krüger or Swissgrid. Consequently, the same coordinate system is used for import and export.

Note: When you Import AutoCAD and MicroStation data, you can use the Coordinate transformation area in the Settings to define how to transform data in the UTM coordinate system into data of a Gauss-Krüger coordinate system.

Click to open the Export, Import Settings dialog box for selecting the coordinate systems:

Country

Select the country and region or federal state.

NTv2 file

Select the required grid file.

Source system

Select the coordinate system of the source data. According to INSPIRE, this is a UTM coordinate system.

Destination system

Select the required Gauss-Krüger coordinate system.

Revert transformation direction

NTv2 files are available for one direction (usually from Gauss-Krüger to UTM). Select this option to change the transformation direction.

Note: As soon as you select a transformation, Allplan transfers 2D data only. Transformation supports only elements that can be found in cadastral plans. XRefs cannot be transferred; therefore, the XRef to smart symbol option is not available.

Info

You can see further information. This also includes sources of supply for grid files, which Allplan is not allowed to provide.

Note: Allplan setup neither includes nor installs these grid files. You can download some free NTv2 files from Allplan Connect. If files are not available, the download package contains the folder structures and information on the sources of supply. When you select these countries and regions in the transformation settings, you will see a corresponding message.

Note: Pay attention to the transformation direction. You must define the systems yourself. When you get geographical data, always ask the supplier for the system in which the data was saved. You must also define the destination system yourself. We recommend that you use the system in which the data was supplied before the switch to UTM. This makes the new data compatible with older data.
