    Dynamic information in GIS systems1995In: Computers, Environment and Urban Systems, ISSN 0198-9715, E-ISSN 1873-7587, Vol. 19, no 2, p. 107-115Article in journal (Refereed)
    Abstract [en]

    Time can be characterized as the fourth dimension of the physical space-time continuum. Time is either a particular instant at which a structure or a process exists or occurs, or a period over which a structure endures or a process continues. From the human point of view, a concrete system can move in any direction on the spatial dimension, but only forward on the temporal dimension. GIS systems generally deal with static information. Static objects can be defined as objects that do not change in a short time period. In many situations, the information in GIS applications does change dynamically. Environmental problems, for example, have a significant dynamic component, which means that the conditions of the real system, at the time the decision is made, are the results of all the past history of the system and influence its subsequent behavior. Dynamicallity in a process may be possible to measure. The measure should include components such as size of change, frequencies of change, and time interval. The dynamicallity of a system should, in addition, include the need of change in representation (for example, how often must the screen be updated) and how time-critical decisions are. Time can be represented by a series of snapshots, and the shorter time periods between the snapshots, the more it imitates a continuous course of events. The time lapse is represented by a minimum of two pictures, up to complete animation. Real time and presentation time are not necessarily the same, as it is desirable to shorten very long time lapses (for example geological changes), and lengthen (prolong) rapid time lapses (such as explosions). We define presentation time as a relation between observation interval (time interval between observations) and picture rate (the rate of changing pictures on the screen). In this paper, some functions for handling dynamic information in GIS systems are presented.

    GIS-application for visualization of streams1994In: Computers, Environment and Urban Systems, ISSN 0198-9715, E-ISSN 1873-7587, Vol. 18, no 2, p. 103-109Article in journal (Refereed)
    Abstract [en]

    Up to now, GIS systems have been used to produce maps. When using these maps, for example, to look at a road section, you are limited to one map-sheet at a time with a specific scale. A common application, for example, in communities and electricity companies, is to include networks such as water pipes, sewage systems, and electric mains. As the lines cross map-sheet borders, it has been necessary to put the map-sheets together. It is useful for communities to have up-to-date and accurate information about water pipes, to be able to locate leaks and to know where to cut off the lines and to know which consumers are affected, when repairing. In the future, GIS systems could also be used as decision and planning support. To be able to use GIS systems for this purpose, it is necessary to improve techniques for visualization of streams (direction and strength) over time. This paper describes a project that aims to develop and evaluate user interfaces for visualization of all kinds of streams and to improve and evaluate methods and CASE tools for development of GIS applications.

    System thinking on Risk Analysis2004In: SABI 2004: Business Systems -- Environmental Contexts, 2004Conference paper (Refereed)
    Abstract [en]

    The word risk originates from the Italian word risicare which means to dare and from this point of view, risk is more of a choice than a fate. Risk is about the actions that we dare to take and these in turn depend on the freedom we have to make choices (Bernstein, 1998). It can also be defined as the possibility of harm or loss to any resource within an information system, which accentuate the importance of identifying the organisation's assets (Ramachandran, 2002).

    The obvious fact that information is one of the most important asset within a company, results in that it is necessary to try to predict the risks that exists against these and consequently also against the organisation's goals and visions. It is impossible to identify all potential risks but a very good tool for identifying as many as possible and then assigning them appropriate protective measures, is the risk analysis.

    Since many significant security processes are built upon risk analysis and also security planning, it is necessary that the analysis is accomplished in an accurate way. This meaning that factors in the inner and outer surrounding environment that could affect the final result also must be taken into consideration, e.g. different communication channels. Thus, a holistic perspective is necessary when performing a risk analysis but also when working with security issues in general.

    Today, security solutions are often focused on technology and not on the system as a whole (Schneier, 2000) and considering that development and use of technology has lead us to think in terms of systems, we mean that this should hold for the information security area as well. Also the fact that the concept of wholeness is very important in information security and that general system theory is a general science of wholeness (v. Bertalanffy, 1969), makes us wonder: what could be more suitable to apply on security issues?

    For that reason, we present some ideas for a modified risk analysis method in this paper, based upon an existing risk analysis used by the case study object The Corporation of Swedish Pharmacies, Apoteket AB. They has recently added two customer care centres to its organisation and as a result of this, also a number of communication channels that are integrated with different information sources that contains classified information, e.g. personal particulars. The ideas of a modified risk analysis could be used by customer care centre organisations using several communication channels. These ideas are influenced by general systems theory that has been combined with a method used to analyse information flows in organisations. We have studied the company's existing risk analysis method and in combination with qualitative data, e.g. interviews, we have some suggestions of a risk analysis that emphasises the holistic perspective and the relations between the different entities in the overall information system.

    The suggested ideas will be reviewed together with the department of IT-security at Apoteket AB and after that tested within the organisation. It is noticeable that like all work with information security, the suggested method is a cyclic process that constantly develops and undergoes changes in relation to its dynamic context. Results and feedback from this implementation will be presented in forthcoming papers during 2004.
