  3. 2. Ontology as Conceptual Schema when Modelling Historical Maps for Database Storage

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Gustaf Svedjemo; Linköpings universitet.; Linköpings universitet.; [2007]

    Sammanfattning : Sweden has an enormous treasure in its vast number of large-scale historical maps from a period of 400 years made for different purposes, that we call map series. The maps are also very time and regional dependent with respect to their concepts. A large scanning project by Lantmäteriverket will make most of these maps available as raster images. LÄS MER

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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Gyözö Jordan; Uppsala universitet.; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; digital elevation model; digital terrain modelling; GIS; morphometry; tectonic geomorphology; Miljöteknik; TECHNOLOGY Other technology Environmental engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper 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

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

    Detta är en avhandling från Division of Occupational and Environmental Medicine

    Författare :Emilie Stroh; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2011]
    Nyckelord :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.

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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Marcus Gustavsson; Uppsala universitet.; [2006]
    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).
