Public Participation in Geocomputation to Support Spatial Decision-making

چکیده
The extent to which computational modelling has influenced and been a part of decision-making in geography and urban planning has a long and distinguished history, as outlined by Geertman and Stillwell (2009) and Batty and Brail (2008) amongst others. With more recent advances in visualisation techniques and the ability of computers to manipulate, process and analyse increasingly complex and growing amounts of spatially referenced data, the application of geocomputation to support decision-making within an online environment continues to grow. GIS as the primary visualisation tool over past decade has matured into a tool that can be increasingly utilised by a wider range of users. Ever since the criticisms of GIS in the mid-1990s (cf. Pickles, 1995), GIS has moved from specialised to lay use, alongside a growth in the ability of a broader range of users to use and understand computerised mapping. While twenty years ago it may not have been envisaged that there could be public participation in geocomputation, today we can build, provide models, and allow access via easy to understand user interfaces that to some extent are starting to replicate systems that were only available to advanced users in the past. With the ever-increasing availability of spatial data there has been a growing demand for translation into usable information that supports many aspects of spatial decision-making. This chapter provides an overview of some of those methods used, as well as two illustrative examples of online geocomputational mapping tools

Developing a Citizen-Centric Spatial Decision-Making System to Support the Process of Participatory Construction in Urban Distressed Textures
Todays, urban distressed textures are considered as a vital concern of managers, particularly in large cities. These areas, which also appear in official parts of cities, are vulnerable because of prospective problems. Lack of proper accessibility, services, facilities, and infrastructures, as well as social, economic, environmental and spatial problems, are key problems of these areas. Althoug...
