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!

This study examined the spatial impacts of oil exploitation in Melut County, South Sudan, at six points in time between 1999 and 2011. Oil is the most important source of revenue for the South Sudanese government. The history of oil exploration and production in the area was characterized by bloodshed, displacement and other grave human rights violations as it unfolded against the backdrop of a vicious civil war. By means of geo‐spatial techniques such as remote sensing and GIS analysis, changes in land use for farming, population growth and the expansion of oil fields were observed and the relationships between them was analyzed. Six points in time – 1999, 2002, 2004, 2006, 2009, 2011 – were chosen to mine Landsat‐5 and ‐ 7 satellite data for features in order to map the state of the area and as a base for further analysis. Two very high resolution scenes from 2004 and 2012 were also applied to explore reported population growth in the town of Paloich. Three features were chosen to be extracted and analyzed: cropland, oil well pads and roads. Feature extraction consisted of onscreen digitization as well as classification approaches. With regard to the latter, pixel‐ and object‐based classification of land cover was performed as a base for further object‐based classification of cropland areas and oil well pads. While the land cover classifications reached high levels of accuracy, the classification of cropland and oil well pads was challenging. Digitized vector data was used instead for GIS analysis of the relationship and interplay between features. Apart from a sharp decline in cropland areas between 1999 and 2002, agricultural lands increased steadily over time and more than doubled in size. Oil infrastructure grew enormously in size throughout the whole time series with 555 oil well pads identified in 2011, compared to a single one in 1999. GIS analysis revealed that causal connections between the increase in all three types of features is likely but can ultimately not be assessed from satellite data alone. Very high resolution imagery and especially ground‐truth data is strongly needed to further investigate the complex interplay between population growth, development of infrastructure and land use changes. The results were presented in 19 maps, providing an overall picture of the developments in the area of interest.
