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.

Hier finden sie die mitunter preisgekrönten Abschlussarbeiten unserer AbsolventInnen!

Topologie vs. Nähe vs. Intervall – Routen-Kalibrierungsmethoden im Vergleich

Diese Arbeit ist online verfügbar: Download


The transfer of route-system stationing from detailed to generalized scales is a necessary process to eliminate differences in stationing of diverging degrees of generalization to display route events with linear refencing in the right location independent from scale. In this thesis, using the example of river networks of different scales, three different methods of route calibration from detailed to generalized scale are executed, employing control points, intersection points and interval points. The three calibration methods are specified and the creation of the calibration points and their use on the generalized water network are explained. The control point method uses topologic features such as source and sink of the water network as calibration points, whereas the intersection point method uses geometric intersections and the interval point method is based on calibration points located at every full kilometer of stationing. After calibration, the results of the three different methods are evaluated taking into account postprocessing efforts of uncalibrated routes, calibration accuracy regarding known stationing values and possible sources of error derived from unemployable calibration points. The results are displayed tabularly concerning the amount of uncalibrated routes, absolute and summarized deviation of stationing and the listing of possible sources of errors in calibration. All in all, the control point method gives the worst results concerning postprocessing efforts, calibration accuracy and possible sources of errors. The results of the intersection point method are in between control points and interval points. From all three calibration methods, the best results derive from the interval points. Concluding the thesis, typical examples of application of the different calibration methods are given. Although the control point method delivers the worst results in direct comparison with the other methods, it is the method of choice if you need topologic identity between scales. An increase in accuracy of the control point method can be achieved by raising the concentration of calibration points using features accoding to the interval point method.
