Because of the infrequent occurrence and dynamic conditions of such events, researchers do not often have the ability to thoroughly study their effects. However, as population distributions and densities place more people at risk of experiencing a disaster, more complete investigations of these events are needed. Recovery, the post-disaster phase of returning to “normalcy,” is one understudied aspect. Gaining a better understanding of this process has important implications for the well-being of disaster-affected people and equitable redevelopment of affected places. This article focuses on one aspect of recovery: spatial decision support for communities. Though the literature on community mapping discusses a variety of cases in which geographic information systems (GIS) are used as a tool to engage the public on a variety of issues, it has yet to address concerns in a post-disaster environment. Furthermore, existing research in geographic information science (GISc) for disasters has only limited dealings with community-focused mapping. The result is that community information needs in a post-disaster environment have not been recognized. Based on existing literature and empirical observations from post-Katrina Louisiana, this article addresses the spatial component of these information needs and how GISc can provide decision-support tools in a post-disaster environment.

The effect of global-scale map-projection knowledge on perceived land area / Sarah E. Battersby in Cartographica, vol 44 n° 1 (March 2009)  

Public [article]  inCartographica > vol 44 n° 1 (March 2009) . - pp 33 - 44 Titre : The effect of global-scale map-projection knowledge on perceived land area Type de document : Article/Communication Auteurs : Sarah E. Battersby, Auteur Année de publication : 2009 Article en page(s) : pp 33 - 44 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Cartographie [Termes IGN] cartologie [Termes IGN] cognition [Termes IGN] lecture de carte [Termes IGN] perception [Termes IGN] projection [Termes IGN] représentation cognitive [Termes IGN] représentation mentale spatiale Résumé : (Auteur) The acquisition and conceptualization of spatial knowledge are important topics in human spatial cognition. At the global scale, maps are our primary graphic source of information; however, they distort the size and shape of geographic features. If a distorted reference is used and the reader assumes it to be accurate, it may inappropriately influence decision making and, possibly, the shape of our global-scale cognitive maps. This paper examines trends in perception of land area, using equal-area and non-equal-area references, as well as investigating how map-projection knowledge can influence interpretation of land area. Results from the land-area studies show that map readers attempted compensation for projection distortion only when using the Mercator projection as a reference, and only for certain regions displayed on the Mercator projection. For other reference materials there is no attempted compensation for perceived distortion, even when participants believe that the reference is distorting land area. It is also apparent that most participants have limited projection knowledge and have difficulty transferring this knowledge to other projections or to practical application tasks. Both of these findings have implications for understanding perceptual issues in map reading and for determining where distortions can be introduced at the encoding stage of cognitive map development.
