3. 2. Terrain Modelling with GIS for Tectonic Geomorphology : Numerical Methods and Applications

   Författare :Gyözö Jordan; Ulf Qvarfort; Tsehaie Woldai; Uppsala universitet; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; digital elevation model; digital terrain modelling; GIS; morphometry; tectonic geomorphology; Miljöteknik; Environmental engineering; Miljöteknik;

   Sammanfattning : Analysis of digital elevation models (DEMs) by means of geomorphometry provides means of recognising fractures and characterising the morphotectonics of an area in a quantitative way. The objective of the thesis is to develop numerical methods and a consistent GIS methodology for tectonic geomorphology and apply it to test sites. LÄS MER

4. 3. The Use of GIS in Assessing Exposure to Airborne Pollutants

   Författare :Emilie Stroh; Avdelningen för arbets- och miljömedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NOx; air pollution; GIS; Exposure assessment; Lead; NO2;

   Sammanfattning : GIS (Geographical Information System) has become a valuable tool in air pollution exposure assessment studies due to its abilities to accurately model and estimate exposure for large populations and areas. The general aim of the work presented in this thesis was to investigate the factors that affect the validity and precision in the assessment of human exposure to airborne pollution using GIS.

5. 4. Development of a Detailed Geomorphological Mapping System and GIS Geodatabase in Sweden

   Författare :Marcus Gustavsson; Else Kolstrup; Harry Seijmonsbergen; Ian S. Evans; Uppsala universitet; []
   Nyckelord :Physical geography and sedimentology; Geomorphology; Geomorphological map; GIS; Sweden; Naturgeografi och sedimentologi;

   Sammanfattning : This thesis presents a method for detailed landscape presentation. The method incorporates both fieldwork-based comprehensive geomorphological description and digital data handling and thus contributes in filling the gap between traditional geomorphological mapping and modern geomorphological studies performed in Geographic Information Systems (GIS).

7. 5. Excavating the Digital Landscape : GIS analyses of social relations in central Sweden in the 1st millennium AD

   Författare :Daniel Löwenborg; Paul Sinclair; Julian D. Richards; Uppsala universitet; []
   Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; landscape archaeology; GIS; Iron Age; Västmanland; burial grounds; Vendel Period; Viking Age; territorial organisation; watersheds; statistical analysis; chronology; discriminant analysis; GWR; spatial analysis; perception; topography; AD 536; Fimbulvinter; property rights; crisis; historical ecology.; Archaeology; Arkeologi; Archaeology; Arkeologi;

   Sammanfattning : This thesis presents a number of GIS based landscape analyses that together aim to explore aspects of the social development in Iron Age Västmanland, central Sweden. From a perspective where nature and culture are seen as integrated in the landscape, differences in the relations to the physical landscape are interpreted as reflecting social organisation. LÄS MER
