Matt Duckham
Enriching imperfect geoinformation

"Imperfection is an endemic feature of geoinformation. User-generated geospatial content (UGGC) in particular has special characteristics that present special challenges, some old and some new, to its enrichment and use. Using a variety of examples from emergency response, place-based search, and environmental monitoring, this talk will focus on specific challenges in four related areas: 1. Understanding imperfection in UGGC, including bias and vagueness; 2. Evaluating the results of enrichment; 3. Identifying not only patterns but the causes of patterns; and 4. Changing attitudes to privacy considerations in UGGC."

Matt Duckham

Matt is Professor in the Department of Infrastructure Engineering, Melbourne School of Engineering, and from July 2015 will be Professor and Deputy Head of the School of Mathematical and Geospatial Sciences at RMIT University, Melbourne. Before moving to Melbourne in 2004, Matt worked at the National Center for Geographic Information and Analysis (NCGIA) at the University of Maine, USA. His research centers on spatial computing with uncertain geographic information, in particular with applications to sensor networks. His is coauthor of the textbook "GIScience: A computing perspective" and author of the book "Decentralized Spatial Computing: Foundations of Geosensor Networks".
