CartoTalk Muki Haklay

We are happy to welcome Muki Haklay of the University College London (UCL) to our colloquium CartoTalks:

Volunteered Geographic Information –
Overview, Quality and Contributors Behaviour

Over the past 5 years a new phenomenon emerged in the area of geographical information. This is the contribution of digital geographical information by non-professional contributors. The information that can be collected through this method ranges from georeferenced photographs to observations that are taken in different parts of the world and to detailed mapping activities. This user-contributed geographical information was termed Volunteered Geographical Information by Goodchild (2007).

In the talk, the background to this phenomenon will be covered, pointing to the technical and societal changes that enable it. Following this overview the issue of data quality and how to evaluate it, will be discussed. Finally the behaviour of participants and their motivation will be covered.

Examples from Flickr, OpenStreetMap and Google Map Maker will be used to illustrate the various aspects of VGI and to highlight that there is a rich seam of empirical data, both quantitative and qualitative, that can be used in VGI research.

Prof. Yan Li (right) and Dr. Yang Cao (left) from South China Normal University visited our research group.

Prof. Yan Li overviewed one of her research topics. The title of her CartoTalk was An Extension of Spatial Functionality for SVG Specification.

Professor Yan LI is vice Director of School of Computer, and Director of Spatial Information Research Center, South China Normal University in Guangzhou, China. She focuses on the theories and methods of spatial information and also on Remote Sensing and GIS applications. Some related projects are: “Spatial Information Integration and applications in Guangdong”, “a prototype of hyper-spectral image processing System development”, “Environment monitoring with hyper-spectra data”, “A XML based spatial information service system” etc.
