A Systems Perspective on Volunteered Geographic Information

A human factors perspective on volunteered geographic information

Validation of Volunteered Geographic Information Landuse Change Using Satellite Imagery

Land use change monitoring is one of the main concerns of managers and urban planners due to human activities and unbalanced physical development in urban areas. In this paper, a combination of remote sensing data and volunteered geographic information was used to assess the quality of volunteered geographic information on land use and land cover changes monitoring. For this purpose, the ORBVIE...

Title Not Required the Wikification of Geospatial Metadata

For decades, metadata has been the ever-present, cure-all solution to heterogeneous data integration and use. Yet, high-quality, ubiquitous metadata is extremely rare in practice. Current volunteered geographic information systems may provide insights on how the scientific community can produce and manage metadata for geospatial data infrastructures.

Volunteered Geographic Information and GIScience

What are the research questions posed by Volunteered Geographic Information (VGI)? Does Geographic Information Science (GIScience) appropriately address them or does it need to shift its attention? I discuss changes to current research agendas, propose an arising grand challenge, and outline some specific new research challenges for scientists working within and outside GIScience.

Assessment of the completeness of Volunteered Geographic Information focusing on building blocks data (Case Study: Tehran metropolis)

Open Street Map (OSM) is currently the largest collection of volunteered geographic data, widely used in many projects as an alternative to or integrated with authoritative data. However, the quality of these data has been one of the obstacles to the widely use of it. In this article, from among the elements related to the quality of volunteered geographic data, we have tried to examine the com...
