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!

Applying Domain Specific Languages and Model-Driven Development to GIS Applications

Diese Arbeit ist online verfügbar: Download

Foundation of this master thesis has been the consideration that Geographic Information Systems (GIS) are a specific kind of information systems, which are significant, different from regular business applications as most people know from their daily experience, This is especially true if looking in detail to the data, their processing and result presentation of those systems. However, the developments in recent years, for example the various map applications on the Internet and virtual globes as well as integration of GIS perations in enterprise information systems show that GIS is moving from a niche IT discipline in the mainstream becoming one of the regular services in information technology. This akes GIS a very good case for the usage of a domain specific language (DSL). At the same time, the industry thrives to make their IT departments and services more efficient and increase or stabilize quality. Developments such as model-driven software development, agile methods and domain specific modeling languages are just some amongst the concepts to be considered. So the author of this master thesis is researching the idea that the specifics of GIS make it worthwhile to apply the concept of a domain specific language (DSL) to GIS application development. Furthermore, the author considers the DSL approach only feasible if it is combined with the manufacturing-like approach of model-driven software development. Looking back in the history of GIS application development and related research shows that there have been various approaches about visual modeling. Looking at these ideas of the beginning or mid 1990’s it becomes clear that these researchers tried to apply concepts, which would be considered under the DSL umbrella today, but at a time when necessary standardization was not nearly as far and ready for practical use as it is today. Based on a sound explanation of current developments around domain specific languages and model driven software development, the GIS domain is positioned in the IT landscape as a horizontal service. The document presents a GIS meta model and ist representation in a domain specific language. The modeling recommendation will be verified in a practical example.
