Recitoire: a tool for qualitative surveys involving citizens in urban planning projects

Ponencias, comunicaciones y pósters presentados en el 17th AGILE Conference on Geographic Information Science "Connecting a Digital Europe through Location and Place", celebrado en la Universitat Jaume I del 3 al 6 de junio de 2014.The difficulty to involve citizens into projects that influence or transform their experience of the urban space is underlined by public authorities and professionals such as urban planners. The implication of citizens in the existing modes of consultation (public meeting, opinions polls) is often limited and not representative. New solutions for facilitating citizens’ involvement in both the diagnosis and the construction of the city need to be found. We propose here a prototype called Recitoire, as a support for qualitative surveys involving citizens in urban planning projects. Using a mobile application, a data collect is performed which includes the path followed by a citizen (her/his trace is kept) and the different kinds of media files she/he produces all along the path to illustrate her/his feelings and impressions on a given thematic - chosen for the survey by urban planners. A server application centralizes the collected data and offers an interface for both their exploration and their exploitation by the actors of the urban project

Recent Developments and Future Trends in Volunteered Geographic Information Research: The Case of OpenStreetMap

User-generated content (UGC) platforms on the Internet have experienced a steep increase in data contributions in recent years. The ubiquitous usage of location-enabled devices, such as smartphones, allows contributors to share their geographic information on a number of selected online portals. The collected information is oftentimes referred to as volunteered geographic information (VGI). One of the most utilized, analyzed and cited VGI-platforms, with an increasing popularity over the past few years, is OpenStreetMap (OSM), whose main goal it is to create a freely available geographic database of the world. This paper presents a comprehensive overview of the latest developments in VGI research, focusing on its collaboratively collected geodata and corresponding contributor patterns. Additionally, trends in the realm of OSM research are discussed, highlighting which aspects need to be investigated more closely in the near future

Quantitative Comparison of Lidar Data and User-generated Three-dimensional Building Models From Google Building Maker

Volunteered geographic information (VGI) has received increased attention as a new paradigm for geographic information production, while light detection and ranging (LiDAR) data is widely applied to many fields. This study quantitatively compares LiDAR data and user-generated 3D building models created using Google Building Maker, and investigate the potential applications of the quantitative measures in support of rapid disaster damage assessment. User-generated 3D building models from Google Building Maker are compared with LiDAR-derived building models using 3D shape signatures. Eighteen 3D building models are created in Fremont, California using the Google Building Maker, and six shape functions (distance, angle, area, volume, slope, and aspect) are applied to the 18 LiDAR-derived building models and user-generated ones. A special case regarding the comparison between LiDAR data and building models with indented walls is also discussed. Based on the results, several conclusions are drawn, and limitations that require further study are also discussed
