UNIGIS Abschlussarbeiten


Der krönende Abschluss eines UNIGIS MSc Studiums ist sicherlich die Master Thesis. Mit ihr belegen unsere MSc-AbsolventInnen, dass sie den akademischen Grad "Master of Science (Geographical Information Science & Systems)" zu Recht führen.  Im UNIGIS professional Studiengang muss keine Abschlussarbeit verfasst werden. Dennoch nehmen einige Studierende die Möglichkeit war, ein Geoinformatikprojekt durchzuführen und entsprechend zu dokumentieren.

Sie sind auf der Suche nach aktueller Literatur zu Geoinformatik-Themen?
Hier finden sie die mitunter preisgekrönten Abschlussarbeiten unserer AbsolventInnen!

Thomas Zwanzger [02-2015]:

Prozessorientierte Anlayse und Optimierung des Geodatenmanagements am Beispiel der Bayerischen Forstverwaltung

Diese Arbeit ist online verfügbar: Download


In this work, the processes in spatial data management in the Bavarian Forest administration were collected, analyzed and possible improvements derived. The results of the process evaluation and of an enquiry amongst spatial data users of the Bavarian State Institute of Forestry (LWF) are part of the potential analysis representing concrete optimization potential. In the field of spatial data updating, single analyzed optimization aspects were designed and technically implemented to Extract‐Transform‐Load (ETL) processes. During the process evaluation an analysis of the process environment in a stakeholder analysis took place. All the actors were considered and their interest and influence to optimize the spatial data management were determined. Stakeholders were assigned to the spatial data management roles. These roles characterize the responsibilities in the modeled business processes. The business processes were based on specific use cases, which reflected the current operational work processes in the field of spatial data management. The process modeling was realized with the Business Process Model and Notation (BPMN). The modeling was done on an overview level with all business processes and a more detailed business process level. The business processes in spatial data management included the areas of procurement, deployment, updating and sharing of spatial data. The survey amongst spatial data users of the LWF in defined aspects of spatial data management has been considered and analyzed from the perspective of GIS users. Another objective of this work was a technical implementation of the optimization potential as sub‐processes of the business process spatial data update designed and implemented in ETL processes. The following optimization aspects have been considered: (1) documentation of processes, (2) the availability of metadata, and (3) quality assurance. Using test data, ETL processes were described from the source‐ to the target‐data‐models, taking into account quality assurance aspects. The provision of metadata was displayed in another ETL process.
