  1. 6. 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).

  3. 7. 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 :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

  4. 8. A GIS-based landscape analysis of dissolved organic carbon in boreal headwater streams

    Författare :Jan-Olov Andersson; Lars Nyberg; Hjalmar Laudon; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; boreal forests; wetlands; vegetation types; headwater streams; catchment hydrology; streamwater chemistry; DOC; GIS; terrain analysis; DEM; slope; wetness index; TWI; Freshwater ecology; Limnisk ekologi; Biology; Biologi;

    Sammanfattning : In boreal catchments, stream water chemistry is influenced and controlled by several landscape factors. The influence of spatially distributed variables is in turn dependent on the hydrological scale. LÄS MER

  5. 9. Predictive Modelling of Aquatic Ecosystems at Different Scales using Mass Balances and GIS

    Författare :Andreas Gyllenhammar; Lars Håkanson; Lars Brydsten; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; mass balance model; dynamic model; scales; marine fish farms; rainbow trout; nutrients; suspended particulate matter; phosphorus; nitrogen; GIS; basin delineation; regionalisation; coastal areas; aquatic foodweb; fishing quotas; Baltic Sea; Archipelago Sea; Okavango Delta; Geovetenskap; Earth sciences; Geovetenskap;

    Sammanfattning : This thesis presents models applicable for aquatic ecosystems. Geographical Information Systems (GIS) form an important part of the thesis. The dynamic mass balance models focus on nutrient fluxes, biotic/abiotic interactions and operate on different temporal and spatial scales (site, local, regional and international). LÄS MER

  7. 10. Metallic particles in GIS : identification and particle lift-off/fall-down on coated electrodes

    Författare :Magnus Holmberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; identification; acoustic measurements; metallic particles; fall-down; lift-oss; dielectric coating; SF6; wire particles; GIS;
