  1. 11. GIS-hydrological modelling in arid lands : a geographical synthesis of surface waters for the African Red Sea region in the Sudan

    Author : Badr-Eldin Taha Osman; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; teknisk geografi; Hydrogeology; geographical and geological engineering; Hydrogeologi; teknisk geologi; runoff.; infiltration; evaporation; rainfall; deterministic and stochastic explanations; weighting methods; hydrological modelling; spatial modelling; GIS; geographical hydrology; the Sudanese Red Sea region; arid lands; water resources;

    Abstract : The magnitude and availability of surface waters in the arid/semi-arid Sudanese Red Sea region has been examined. In conjunction with the research objective, opinions and methodologies applied by previous researchers have been assessed. The study applied a geographical hydrological synthesis within a GIS framework. READ MORE

  2. 12. Remote Sensing and Gis for Groundwater Assessment in Hard Rock Areas. Applications to Water Well Siting in Ghana and Botswana

    Author : Per Sander; Chalmers University of Technology; []
    Keywords : probabilistic approach; GIS; remote sensing; Ghana; hard rock; Botswana; groundwater assessment; lineaments;

    Abstract : Different types of remote sensing data have been evaluated in this thesis with respect to their potential use in groundwater assessment in hard rock areas. The primary objectives of the study have been (1) to evaluate the interpretation of groundwater indicators from high resolution satellite images and aerial photography and (2) to investigate how remote sensing interpretations subsequently can be integrated with other pertinent data, as a decision support in water well siting under difficult hydrogeological conditions.

  3. 13. Remote Sensing and GIS : Applications for Groundwater Potential Assessment in Eritrea

    Author : Semere Solomon; KTH; []
    Keywords : Remote sensing; Geographic Information Systems; groundwater; geomorphology; Digital elevation model; lithology; hard rock; lineament; structures; hydrogeology; Eritrea;

    Abstract : An integrated approach with remote sensing, GeographicInformation Systems (GIS) and more traditional fieldworktechniques was adopted to assess the groundwater potential inthe central highlands of Eritrea. Digitally enhanced colorcomposites and panchromatic images of Landsat TM and Spot wereinterpreted to produce thematic maps such as lithology andlineaments. READ MORE

  4. 14. Ontology as Conceptual Schema when Modelling Historical Maps for Database Storage

    Author : Gustaf Svedjemo; Erland Jungert; Wollter Arnberg; Gustav Svedjemo; GIS - Geografiska informationssystem) Institutionen för datavetenskap Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; HUMANITIES; HUMANIORA; NATURVETENSKAP; HUMANIORA; NATURAL SCIENCES; HUMANITIES; ontology; historical maps; database modelling; GIS; Geographical Information Systems; archaeology; history; ontologi; historiska kartor; databasmodellering; GIS; geografiska informationssystem; arkeologi; historia; Computer science; Datavetenskap; History subjects; Historieämnen;

    Abstract : 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. READ MORE

  5. 15. UNDERSTANDING URBAN PATTERNS Qualitative and Quantitative Approaches

    Author : Vânia Aparecida Ceccato; KTH; []
    Keywords : urban quality; GIS; spatial statistics;

    Abstract : In this thesis, the main field of study is urban patternsand the methodological issues involving the analysis of spatialdata across urban space. Four particular aspects are chosen toillustrate the dynamics of urban space, using Stockholm Countyas case study. READ MORE
