The latest outputs from researchers, alumni and friends at the UCL Centre for Advanced Spatial Analysis (CASA).
Following on from the last post, we (Hossein Amiri, Shiyang Ruan, Joon-Seok Kim, Hyunjee Jin, Hamdi Kavak, Dieter Pfoser, Carola Wenk and Andreas Zufle and myself) have a paper in the Data and Resources trac…
Continue reading »In the past the blog has explored the creation of social networks for models. Keeping with this vain of research, I was fortunate to work with Ketevan Gallagher, Taylor Anderson and Andreas Züfle to consider the role of locatio…
Continue reading »Often we are building geographically explicit agent-based models we spend a lot of time creating the synthetic population to instantiate our artificial world. We have tired to overcome this with creating methods to generate such populations (see this o…
Continue reading »Over the years we have developed several agent-based models that have explored various aspects of farming, ranging from farmers selling their land for development to that of water reuse. Keeping with this theme, we have a new paper with Kazi Ullah and …
Continue reading »In the past, this blog has explored several aspects of Detroit, such as how well its covered with Volunteered Street View Imagery or how through the use of agent-based models one can explore issues with urban shrinkage. Keeping up with the theme of shr…
