    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

  2. 2. On development of information systems with GIS functionality in public health informatics : a requirements engineering approach

    Author : Christina Ölvingson; Linköpings universitet; []

    Abstract : Public health informatics has in recent years emerged as a field of its own from medical informatics. Since public health informatics is newly established and also new to public health professionals, previous research in the field is relatively scarce. READ MORE

  3. 3. Geographical Information Systems (GIS) as a tool for analysis and communications of multidimensional data

    Abstract : This study set out to develop a framework within which the use of Geographical Information Technologies (GITs) can be enhanced in Road Infrastructure Maintenance (RIM) in Uganda. Specifically it was guided by 3 objectives; 1. To assess the gaps in the use of GITs for RIM in Uganda and the limitations to accessing these technologies, 2. READ MORE

  5. 5. Understanding Human Mobility with Emerging Data Sources: Validation, spatiotemporal patterns, and transport modal disparity

    Author : Yuan Liao; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; travel mode; data mining; travel time; mobility; social media data; gravity model; Twitter; geographical information systems;

    Abstract : Human mobility refers to the geographic displacement of human beings, seen as individuals or groups, in space and time. The understanding of mobility has broad relevance, e.g., how fast epidemics spread globally. READ MORE
