This article presents an innovative approach to citizen-led production of Web-based geographic information where new and/or existing digital map features are linked to annotations or commentary and citizens engage in synchronous and/or asynchronous discussion. The article discusses the relationship of the approach to public participation geographic information systems (PPGISs) and the emerging challenges associated with volunteered geographic information. A custom-developed, open source software tool named MapChat is used to facilitate the citizen inputs and discussions. The information generated from applying the approach through a series of community workshops is presented and discussed in light of current issues in PPGIS and volunteered geographic information research.

There is growing interest in extending GIS to support pluralistic decision-making processes where the perspectives and objectives of different stakeholders must be represented and, if possible, distilled into strategies that satisfy all decision participants. Augmenting GIS capabilities with multi-criteria decision-making (MCDM) methods allows the relative attractiveness of different alternatives (e.g. sites, land-use plans, etc.) to be evaluated in light of subjectively weighted decision criteria. This paper presents a generic methodology for investigating the spatial dimension of multi-criteria weight sensitivity. The methodology is particularly well suited to the spatial domain, as it provides insight into both the robustness of individual stakeholder's evaluations as well as the geographic dimension of weight sensitivity. The methodology is illustrated using a study in which a small group of individuals representing different interests evaluated sites for new tourism development on the island of Grand Cayman, BWI. The results demonstrate how the proposed approach can aid users' understanding of a decision issue and potentially increase confidence in evaluation outputs by providing users with mechanisms to define non-statistical confidence intervals for weights and to visualize weight sensitivity cartographically. The paper concludes by discussing the broader value of this approach in other GIS-MCDM contexts and outlines areas for further research.

It is essential that the pedestrian environment accommodates all users so they can participate in everything the community has to offer. However, people with disabilities (PWDs) often find it difficult to navigate this environment because of physical and social accessibility factors. While we know a great deal about which factors act as barriers and facilitators to mobility, we do not know enough about how they influence navigation (i.e. planning a route, en route decisions, and route learning) or how they can be improved. A scoping review was conducted to identify these factors, assess their implications, and suggest future directions. In total, 3394 studies were found and screened, 163 full-text articles were reviewed, and 37 articles met the inclusion criteria for the final review. These studies focused on those with visual impairments, navigating crosswalks, and the cognitive elements of navigation. Future research is needed that includes more types of disabilities, considers the navigational process from planning to arrival, and evaluates interventions.
