  1. 1. Methods to Improve and Evaluate Spatial Data Infrastructures

    Author : Ara Toomanian; Centrum för geografiska informationssystem (GIS-centrum); []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spatial data infrastructure; evaluation; balanced scorecard; geoportals; clearinghouse; web cartography; expert system; web services;

    Abstract : This thesis mainly focuses on methods for improving and evaluating Spatial Data Infrastructures (SDIs). The aim has been threefold: to develop a framework for the management and evaluation of an SDI, to improve the accessibility of spatial data in an SDI, and to improve the cartography in view services in an SDI.

  2. 2. GIS and Health: Enhancing Disease Surveillance and Intervention through Spatial Epidemiology

    Author : Augustus Aturinde; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spatial epidemiology; spatial econometrics; HIV-TB; CVD; cancer;

    Abstract : The success of an evidence-based intervention depends on precise and accurate evaluation of available data and information. Here, the use of robust methods for evidence evaluation is important. Epidemiology, in its conventional form, relies on statistics and mathematics to draw inferences on disease dynamics in affected populations. READ MORE

    Author : Niclas Rudolfson; Lund Pediatrik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Global health; global surgery; Surgery; Anaesthesia; Obstetric;

    Abstract : Background. A once commonly held belief was that surgery is too complicated, too expensive, and too ineffectively addressing a too minor proportion of the burden of disease to deserve priority in a setting of scarce healthcare resources in low- and middle-income countries. READ MORE

  4. 4. Temporal support for land information systems in object-oriented modeling

    Author : Jaeik Liou; KTH; []
    Keywords : ;

    Abstract : With the development of distributed object technologies andthe overwhelming advent of the Web, an object-oriented datamodel for GIS/LIS is proposed, possessing significantlyincreasing importance and application, when movingfrom astatic position to a distributed and heterogeneous view. Theconceptual model of land information hinges on a complexspatio-temporal object model for defining not only collectionsof land parcel objects but also distributions of them within afour domain framework.

  5. 5. Diversified Retrieval of Spatial Data with Context

    Author : Georgios Kalamatianos; Georgios J Fakas; Aristides Gionis; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Proportionality; Diversity; Keyword Search; Spatial Data; Ranking; Computer Science; Datavetenskap;

    Abstract : The abundance and ubiquity of spatial datasets necessitates their effective and efficient retrieval. For instance, on the web, there are datasets with GIS objects or POIs (e.g. Spatialhadoop datasets), datasets with geo-tagged photographs (e. READ MORE
