  1. 1. An Optimisation Approach to Cartographic Generalisation

    Författare :Lars Harrie; Centrum för geografiska informationssystem (GIS-centrum); []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; incremental generalisation; multiple representation; least-squares method; optimisation; cartographic constraints; displacement; cartographic generalisation; graphic generalisation; map production; object-oriented spatial databases; Physical geography; geomorphology; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi; Technological sciences; Teknik;

    Sammanfattning : Cartographic generalisation is the process of simplifying a representation to suit the scale and purpose of a map. As such, generalisation has always been a central part in map production. This thesis is a contribution to the ongoing work on automating cartographic generalisation. LÄS MER

  3. 2. Generalisation Methods for Propagating Updates between Cartographic Data Sets

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multiple representation database; automated cartographic generalisation; incremental generalisation; displacement; cartographic constraints; object-oriented database;

    Sammanfattning : Automation is increasingly important in producing and maintaining cartographic data sets. This thesis deals with automatic methods to propagate updates between cartographic data sets. LÄS MER

  4. 3. Making 21st Century Maps Legible - Methods for Measuring and Improving the Legibility and Usability of Real-Time Maps

    Författare :Hanna Stigmar; Fastighetsvetenskap; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The research presented in this thesis has focused on methods for improving the legibility and usability of maps in real-time map services. The aim has been threefold: to create methods to increase the cartographic quality of maps in map services, to develop methods to measure the legibility, as perceived by the user, and to evaluate the quality of maps.

  5. 4. Geospatial data and knowledge on the Web : Knowledge-based geospatial data integration and visualisation with Semantic Web technologies

    Författare :Weiming Huang; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geospatial data integration; data visualisation; Semantic Web; Linked Data; ontology;

    Sammanfattning : Geospatial information is indispensable for various types of spatially informed analysis and decision-making, such as traffic analyses, and natural resource management. In addition, geospatial information is one of the most powerful information integrators to bridge diverse sources of information. LÄS MER
