GIS for XFEL :

For geodetic purposes a geographic information system (GIS) is the appropriate tool.

Since 2004 a modern GIS based on a Oracle Database is available at DESY. The survey group is mainly responsible for the contents of the system while the group IPP (Information Management, Processes and Projects) is running the system technically.

The data can be accessed by the native system running on some PCs for data acquisition or for information only on a web browser.

The content is structured in modules which can be shown in any combination. Concerning XFEL there are

• The basic map including terrain altitudes and supply circuits

• Geodetic reference points

• A overall plan like a city map

• The XFEL planning data including foreseen machine components

Additional there are official topographic maps, cadastral maps and aerial images which after geocoding can be shown together with the GIS contents.

XFEL Co-ordinate Systems :

Global machine co-ordinate systems:

As it is the special thing about GIS to handle spatial data it is crucial to have all geometry data in one co-ordinate system. This has to be defined carefully.

Future Prospects

Earth Systems :

For setting out buildings and components with conventional survey instruments it is necessary to have co-ordinates in a system following the earth curvature.

The earth model shall represent the real gravity field as good as possible to fulfill the tangent constraints. It was chosen a sphere with the mean radius of curvature following the XFEL route on the Bessel ellipsoid (6390km).

The datum of this system shall be chosen so that distortions due to the projection on a plane are minimal (1000m from the beginning). This point becomes co-ordinates in the HERA earth system so that both systems are in principle the same. They differ in the boundary area by 0.1mm in height.

At last the co-ordinates are charged with addition constants so that they are positive and differ substantially in size (5000/10000 for the datum point).

To have a consistent system for all accelerators at DESY the HERA earth system was chosen as reference for the GIS.

Local Systems :

•Each building or tunnel and each virtual room has its own local co-ordinate system.

• The origins and orientations of these systems are defined in a document called BO-list (from base orphan).

• With the help of this list all 3D models can be put together as an assembly in one the global machine systems.

Future Prospects

Future Prospects :

• Update the system to a more modern one including FDO technique, closer integration of native and web system and making it easy for the user to adapt the design of the maps.

• Introduce special modules for water, waste water, district heating and electricity giving the responsibility for the technical data to the appropriate working group.


Conclusion :

Our experience has taught that specially for large accelerator centers a GIS is not only a nice to have but a must.
