We propose a novel method of assessing OpenStreetMap data using the concept of Data Maturity. Based on research into data quality and trust in user generated content, this is a set of measurements that can be derived from provenance data extracted from OpenStreetMap edit history.

Management and validation of VGI
2013 1st International Conference on Emerging Trends and Applications in Computer Science, 2013With the advent of web based geospatial applications or geo-portals which allow for access and exchange of geographic information through the internet, the concept that enables users or individuals to contribute geographic content and other information related to it, has become a new area of research in Geographic Information System(GIS).

Virtual geographic information system (VGIS)
Proceedings of the Twenty-Eighth Hawaii International Conference on System Sciences, 1994The implementation and proficient use of GISs has become so complicated that it is growing towards a domain in itself. The "Virtual GIS" (VGIS) aims at the use of the "knowledge base" that is inherent in a GIS for the automatic interpretation of remotely sensed images.

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.

The advent of user-generated content, crowdsourcing and other forms of lay data generation have led to opposing arguments about the quality and reliability of data in the geoweb,. The main focus of this chapter is an ‘experiment' to test the quality, validity and lay monitoring of volunteered geographic information (VGI) data.

GeoBI and Big VGI for Crime Analysis and Report
2015 3rd International Conference on Future Internet of Things and Cloud, 2015Geographic Information Systems (GIS) have left being a tool for academics and specialist enterprises and it is becoming a massive tool. Initially, citizens had a passive interaction about this kind of systems, which were used to retrieve data of interest on a map, however their role has changed and has become a major contributor of geographic ...
