  1. 1. Qualitative analysis of challenges in geodata management : An interview study analysing challenges of geodata management in Swedish companies and public authorities

    Kandidat-uppsats, KTH/Geoinformatik

    Författare :Josef Kalhory; [2022]
    Nyckelord :Geodata Management; GIS; Metadata; SDI; Data Portals; ML; AI; Open Source; Geodataförvaltning; GIS; Metadata; SDI; Dataportal; ML; AI; Öppen Källkod;

    Sammanfattning : With a constant increase of the datasphere so does the need for proper management of this data in order to minimise potential inefficiencies when it comes to the usage of this data. Geodata is no exception to the need of management. LÄS MER

  3. 2. AN ONTOLOGICAL APPROACH TO CONSIDERING METADATA ACROSS SPATIAL AND NON-SPATIAL DATASETS

    Master-uppsats, Lunds universitet/Institutionen för kulturgeografi och ekonomisk geografi

    Författare :Alannah Finn; [2021]
    Nyckelord :Metadata; ontology; interoperability; spatial; dataset; GIS; DHS Surveys; Social Sciences;

    Sammanfattning : This study presents the case for taking an ontological approach to metadata analysis as a means of facilitating enhanced interoperability across spatial and non-spatial datasets in GIS. A detailed literature review was undertaken in order to understand metadata definitions, concepts and usage, particularly as a “primary interoperability enabler” (Danko, 2008). LÄS MER

  4. 3. Comparison of geospatial support in RDF stores: Evaluation for ICOS Carbon Portal metadata

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Amir Raza; [2019]
    Nyckelord :Geography; Geographical Information Systems GIS ; GeoSPARQL; Geospatial query language; RDF stores; Java Programming; RDF4J; Jena; Virtuoso; Stardog; GraphDB; Earth and Environmental Sciences; Technology and Engineering;

    Sammanfattning : The evolution of World Wide Web (WWW) into semantic web is happening with the aid of standards like Resource Description Framework (RDF), SPARQL and a few others from World Wide Web Consortium (W3C). Over the years, semantic data management technologies have been introduced as software platforms commonly known as RDF stores. LÄS MER

  5. 4. Closed To Open Sourve GIS : First Steps In Reverse Engineering ESRI's Layer Defintion File Format

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Ola Ardung; [2017]
    Nyckelord :GIS; .lyr; Reverse engineering; FOSS; Open Source;

    Sammanfattning : Visualization of digital geographic data is often accomplished through custom symbology that is saved in a proprietary format called a layer file (.lyr). The sharing of free geographical information system (GIS) data can be limited as the symbology data is bound inthe .lyr file format. LÄS MER

  7. 5. Development of a Web GI System for Disaster Management

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap; Lunds universitet/Lantmäteri (CI)

    Författare :Anton Lundkvist; [2016]
    Nyckelord :Web GIS; Disaster Management; GIS; Web Development; Web application; Technology and Engineering; Earth and Environmental Sciences;

    Sammanfattning : Spatial data is an important and necessary ingredient in the disaster management cycle. The preparedness phase requires simulation of disastrous events, identification of disaster management hotspots and creation of hazard- and risk maps. LÄS MER
