Advancing Science with VGI: Reproducibility and Replicability of Recent Studies using VGI

Commentary: whither VGI?

For the most part, we find our way around the planet by tapping memory, perhaps by recalling past routes, or sometimes by accessing stored mental images that approximate maps. In other cases, however, we must rely on information collected and made available to us by others. People visiting strange cities need street maps to help them find their way around; planners need maps of wetlands and oth...

Quality Attributes & Methods for VGI

The widespread use of GPS-equipped devices such as smartphones and tablets and the easy handling of online maps are simplifying the production and dissemination of volunteered geographic information (VGI) through the internet. VGI systems collect and distribute this type of information and can be used, for example, in cases of natural disasters, mapping, city management, etc. In some cases, the...

Understanding Design with VGI using an Information Relevance Framework

Volunteered Geographic Information (VGI) has the potential to provide benefit to endusers over and above that of Professional Geographic Information (PGI). A multi-methods approach consisting of participatory observation, focus groups and diary studies, was used to study how VGI and PGI were actually used by a target user group. A theoretical framework of information relevance was used to under...

Evaluating Reputation in VGI-Enabled Applications

Volunteered Geographic Information (VGI) is an approach to crowdsource information about geospatial objects around us, as implemented in Open Street Map, Google Map Maker and WikiMapia projects. The value of this content has been recognized by both researchers and organizations for acquiring free, timely and detailed spatial data versus standard spatial data warehouses where objects are created...
