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!

Auto-generated routing instructions with landmarks for indoor navigation

Diese Arbeit ist online verfügbar: Download


This thesis deals with the question of how route instructions for indoor navigation can be generated automatically based on the information available in spatial indoor databases. Landmarks can significantly improve the quality of routing instructions. However, in particular, indoor navigation poses special challenges to the automatic creation of routing instructions with landmarks. In order to create routing instructions including landmarks automatically, three phases are specified in this thesis: landmark identification, landmark selection and landmark integration. This thesis aims at developing an “indoor landmark navigation model” (ILNM), which defines the processes and algorithms for these three phases. It is based on the “landmark navigation model” (LNM) by Duckham et al. (2010) (Matt Duckham et al.(2010). “Including landmarks in routing instructions”. In: Journal of Location Based Services 4.1, pp. 28–52). As the LNM was developed for outdoor environments and for a different kind of data source, it had to be adapted to the requirements and challenges of indoor navigation. In order to evaluate the ILNM, it was applied to the data of the Campus GIS of the Vienna University of Economics and Business (WU). After feature types had been selected and rated for their landmark suitability, the landmark selection and integration algorithms were applied to three sample routes of the Campus WU. he generated route instructions demonstrate that the ILNM basically produces correct route instructions including landmarks. A comparison to solely metric-based routing instructions shows that landmarks are important to increase the quality of indoor route instructions. However, the generated route instructions also disclose some gaps in the model and unresolved challenges of automatic indoor routing generation. Finally, suggestions are given for future work to overcome some of these problems.
