This paper presents a Geographic Information System based Multicriteria Decision Making approach for evaluating accessibility to public parks in Calgary, Alberta. The approach involves the weighted linear combination with the entropy weighting method for obtaining the criterion (attribute) weights. The paper demonstrates a core-periphery pattern of accessibility to public parks in Calgary. Furthermore, the pattern has shown tendency to be more polarized between the year of 2006 and 2011. The results of this research can help the park planning authorities in identifying the needs for improving the accessibility to public parks, monitoring the changes of accessibility patterns over time, and locating new public parks. The results can also help the general public to better understand the spatial relationship between their neighbourhoods and public parks in the city.

This paper presents a Geographic Information System (GIS) based multicriteria decision analysis approach for mapping accessibility patterns of housing development sites in Canmore, Alberta. The approach involves integrating two multicriteria decision methods (Analytical Hierarchy Process and Ordered Weighted Aver-aging) in a raster GIS environment, and incorporating the linguistic quantifier concept as a method for ob-taining the order weights. The approach facilitates a wide range of location (decision) strategies to be gener-ated and examined. The aim of the study is to help the housing development authorities in addressing the uncertainty involved in the decision making process, achieving a better understanding of the alternative ac-cessibility patterns. It also assists the authorities in evaluating and prioritizing the potential housing devel-opment sites in terms of accessibility levels.

This paper focuses on evaluating usability of a Web-based Public Participatory GIS (Web-PPGIS) in the context of a real-world application. The empirical study involves the use of ArgooMap to support users in an online public participatory decision-making process where the users are asked to find the “best” location for a new parkade in the downtown of Canmore, Alberta. The datasets on system usability have been collected automatically using UsaProxy software.We have found that there are significant differences in the system usability among the participants. The system usability is higher for users with GIS experience, higher education levels, and more web surfing experience. The findings provide insights for Web-PPGIS practitioners to advance such systems. It is noticed that the way the Web-PPGIS website was advertised may influence the results. An approach to avoid this problem is needed.

This paper explores the relationships among the usability of a Web-based Public Participatory GIS (Web-PPGIS), the degree of pre-decisional engagement and decision outcomes in the context of a real-world participatory planning project. ArgooMap is used to support local residents in an online procedure for determining the "optimal" location of a new parkade in Canmore, Alberta. UsaProxy is employed to automatically collect the datasets on the system usability and the degree of pre-decisional engagement. This research shows that the degree of pre-decisional engagement depends significantly on the system usability measured in terms of the system efficiency, effectiveness and the user satisfaction with using the system. In addition, the degree of pre-decisional engagement has a significant effect on the decision outcomes (i.e., the rankings of candidate sites). These findings provide clues for advancing Web-PPGIS.

... This model used scoring for determining which disaster resilience classification from the result of buffer operation. Scoring or technically called as Simple Additive Weighting (SAW) methods is based on the concept of weighted average by giving the score which represent the relative importance of each other variable[21], the higher score indicates that the variable more important than others.Overlay spatial analysis is used in this model to facilitate the second assumption. Union operation is one of the overlay spatial analysis which combines more than one feature class (either for the spatial feature or attribute table) into a new feature class[22]. ...

... The integration of MCDM with a geographic information system (GIS) assists the decision-maker in exploring and realising the desirability of alternatives. Usually, in decision-making problems, uncertainty arises due to experts' advice (Meng and Malczewski, 2015). For this study, an integrated MCDM approach has been adopted, where we attempted to integrate AHP with VIKOR and WSM techniques to estimate the seismic vulnerability of West Bengal. ...

... Physical challenges such as visual impairments or reduced fine motor skills, as well as more psychological barriers such as technological self-efficacy can make the use of digital technologies more challenging for some older adults (Gottwald et al. 2016;Vrenko and Petrovič 2015;Carpenter and Buday 2007;Nielsen 2013). Although it is not older adults alone that face these challenges-nor all older adults-increasing accessibility to meet these needs can improve the user experience for the wider public as a whole, for example through non-digital methods (Gottwald et al. 2016;Meng and Malczewski 2010). The inclusion of multiple viewpoints across society is central to the benefits and aims of Participatory Mapping, making it important that an appropriate level of accessibility is maintained for the given situation (Radil and Jiao 2016). ...

... Multicriteria decision-making (MCDM) is a decision-making tool that uses multiple criteria for the evaluation of complex, multidimensional trade-offs between various options, such as locations or the suitability of a region (Grima et al. 2018;Malczewski 2006;Meng et al. 2011). In conjunction with GIS, the MCDM method enables categorizing, examining, and properly organizing the available information on spatial planning options. ...

... The study aimed to evaluate a framework specifically designed for mobile environments, based on the usability characteristic outlined in the ISO 9126 Software Quality Standard. Meng et al. [15] conducted an assessment of the usability of a Web-based Public Participatory GIS (Web-PPGIS) in a practical application setting. The researchers administered a questionnaire to participants and discovered notable disparities in system usability. ...
