Designing effective public participation

This paper reviews the various connections that can exist between the design of participatory processes and the different kind of results that they can entail. It details how effective participatory processes can be designed, whatever are the results that participation is deemed to elicit. It shows the main trends pertaining to design choicesand considers how to classify different arrangements in order to choose from among them. Then the paper deals with the main dilemmas that tend to arise when designing participatory processes. Thanks to this review, the paper argues that participatory processes tend to display a certain degree of ambivalence that cannot be completely overcome through the design choices

Identification of practically visible spatial objects in natural environments

Image retrieval of landscape photographs requires accurate annotation using multi-faceted descriptions relating to the subject and content of the photograph. The subject of such photographs is dominantly the terrain and spatial objects visible from the photographer’s viewpoint. While some spatial objects in the background may be obscured by foreground vegetation, other visible spatial objects beyond a certain distance may not present noteworthy elements of the captured scene (such as distant houses). Our aim is to assess approaches to improve the identification of practically visible spatial objects for image annotation. These approaches include the consideration of the apparent spatial object size and landcover information about occluding vegetation. These inputs are used to enhance viewshed analysis to accurately identify only spatial objects practically visible and therefore likely to be notable subjects of a photograph. The two approaches are evaluated in an experiment in a semi-rural area of Switzerland, whose results indicate that visual magnitude is key in accurate identification of visible spatial objects
