ASSESSING VOLUNTEERED GEOGRAPHIC INFORMATION (VGI) QUALITY BASED ON CONTRIBUTORS' MAPPING BEHAVIOURS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013
VGI changed the mapping landscape by allowing people that are not professional cartographers to contribute to large mapping projects, resulting at the same time in concerns about the quality of the data produced.

A characterization of Volunteered Geographic Information [PDF]

open access: yes, 2010
This paper characterizes the Volunteered Geographic Information (VGI) phenomenon and explores comprehensively its relation with SDI. The SDI component view is used as common framework for describing the main characteristics of VGI and as framework for

Asymmetry of the Ferroelectric Phase Transition in BaTiO3

open access: yesAdvanced Materials, EarlyView.
Phase transitions are typically assumed to behave identically in forward and reverse. This work shows that in the ferroelectric material barium titanate this is not true: heating drives an abrupt, first‐order jump, while cooling gives a smooth, continuous change.
