Assessment of volunteered geographic information for vegetation mapping
Environmental Monitoring and Assessment, 2020Vegetation mapping requires extensive field data for training and validation. Volunteered geographic information in the form of geotagged photos of identified plants has the potential to serve as a supplemental data source for vegetation mapping projects.

Merging Volunteered Geographic Information Systems
2023This project determines how two different systems based on geographic user-generated content can work together to allow the content to be made more accessible. This project’s objective is to determine the technical and social issues involved with allowing information to be transferred between systems.

Tracking via Volunteered Geographic Information
2020Over the past 20 years, the use of location-based tracking has become increasingly popular. The introduction of GPS technology into devices such as phones and watches, and its incorporation into tracking apps, has led to widespread use of apps which track activities, particularly those of a sporting nature. There are now over 318,000 health and fitness

Photo Based Volunteered Geographic Information Initiatives
International Journal of Agricultural and Environmental Information Systems, 2014Volunteered Geographic Information has become exponentially available over the Web in the last years. This availability can hide a vast geographical richness and provides us with both a great opportunity to explore new ways to use it and also big challenges related with its unstructured nature. This paper conducts a preliminary analysis of the adequacy
