Background:

This brief article was prepared to inform the development of the AGI Foresight document looking forward to the medium term from 2015. The article arises from the work of COST Action TD1202 and authorship order is relatively arbitrary,... Read More about Current status and future trends in crowd-sourcing geographic information.

Enhancing the spatial resolution of satellite-derived land surface temperature mapping for urban areas (2015)
Journal Article
Feng, X., Foody, G., Aplin, P., & Gosling, S. (2015). Enhancing the spatial resolution of satellite-derived land surface temperature mapping for urban areas. Sustainable Cities and Society, 19, https://doi.org/10.1016/j.scs.2015.04.007

Land surface temperature (LST) is an important environmental variable for urban studies such as those focused on the urban heat island (UHI). Though satellite-derived LST could be a useful complement to traditional LST data sources, the spatial resol...

Usability of VGI for validation of land cover maps (2015)
Journal Article
Fonte, C., Bastin, L., See, L., Foody, G. M., & Lupia, F. (2015). Usability of VGI for validation of land cover maps. International Journal of Geographical Information Science, 29(7), https://doi.org/10.1080/13658816.2015.1018266

Volunteered Geographic Information (VGI) represents a growing source of potentially valuable data for many applications, including land cover map validation. It is still an emerging field and many different approaches can be used to take value from V... Read More about Usability of VGI for validation of land cover maps.

Valuing map validation: the need for rigorous land cover map accuracy assessment in economic valuations of ecosystem services (2015)
Journal Article
Foody, G. M. (2015). Valuing map validation: the need for rigorous land cover map accuracy assessment in economic valuations of ecosystem services. Ecological Economics, 111(March), https://doi.org/10.1016/j.ecolecon.2015.01.003

Valuations of ecosystem services often use data on land cover class areal extent. Area estimates from land cover maps may be biased by misclassification error resulting in flawed assessments and inaccurate valuations. Adjustment for misclassification...

Rating crowdsourced annotations: evaluating contributions of variable quality and completeness (2013)
Journal Article
Foody, G. M. (2014). Rating crowdsourced annotations: evaluating contributions of variable quality and completeness. International Journal of Digital Earth, 7(8), 650-670. https://doi.org/10.1080/17538947.2013.839008

Crowdsourcing has become a popular means to acquire data about the Earth and its environment inexpensively, but the data-sets obtained are typically imperfect and of unknown quality. Two common imperfections with crowdsourced data are the contributio... Read More about Rating crowdsourced annotations: evaluating contributions of variable quality and completeness.

Assessing the accuracy of volunteered geographic information arising from multiple contributors to an internet based collaborative project (2013)
Journal Article

Transactions in GIS, 17(6), 847-860. https://doi.org/10.1111/tgis.12033

The recent rise of neogeography and citizen sensing has increased the opportunities for the use of crowdsourcing as a means to acquire data to support geographical research. The value of the resulting volunteered geographic information is, however, o...
