    1. 1. Making thematic maps in ArcGIS with emphasis on user issues Alena VONDRÁKOVÁ alena.vondrakova@upol.cz Second InDOG Doctoral Conference 13–16 October 2013
    2. 2. Concept of Technological and Non-technological Aspects

    4. 4. Non-Technological Aspects
    5. 5. User Issues • combination of social, professional and user aspects • complex process with many internal and external factors How to make thematic maps with emphasis on user issues?
    6. 6. Objective Research Methods • the influence of the psychological aspects on the perception of users can be assessed by the eye-tracking technology • individual’s eye movements are measured • there are monitored localization of eye-movement in any given time
    7. 7. Eye-tracking Technology SMI RED 250
    8. 8. Case studies • the full potential of evaluation methods, which include research target groups, interviews with experts, direct observation, survey and study of literature, was utilized • there were used exploratory, descriptive, explanatory and testing approaches • each evaluation of non-technological aspect was addressed in three basic levels – definition, realization and the description of the case study and partition findings and recommendations • the following example is only a sample case study
    9. 9. Case Study Methods of Cartographic Visualization • lack of standardization or mandatory rules in cartography • choice of method of cartographic visualization depends on the opinion of the map author • way of expressing the same information by different methods of cartographic visualization leads to different user perception • maps have to help their users to better understand geospatial relationships, not to confuse the user • users have to get the information as quickly as possible and as accurately as possible

    21. 21. Producers evaluation (on-line questionnaire)
    22. 22. Findings • users are the key determinants of any cartographic work • it is important to identify needs of the target users • user needs may differ with respect to their intellectual and physical condition • maps for people with specific disabilities are frequently missing • adaptation of cartographic production to the target group of users has a significant impact on technological treatment • view of users, creators and producers to the offer of cartographic production for the demand users vary considerably • choice of methods of cartographic representation and their applications can have a significant impact on the perception of presented phenomena
    23. 23. Recommendations • it is needed to focus more on specific user needs • it is necessary to test created cartographic works (before their mass production) on user perception – it is appropriate to use a combination of modern methods • eye-tracking technology and standard approaches can be used (questionnaires, interview and more) • cartographic works should be adapted to the specific needs of users in the best possible level
