Spatial Interaction

Posted on January 20, 2012 by Michael Batty

Spatial Interaction from now on and I promised you a short piece that I had written as a general introduction but I don’t have it digitally. It is called “Spatial Interaction” in Encyclopaedia of Geographic Information Science edited by Karen Kemp, Sage, 2007, 417-419. I have the book in self-storage in Bath (don’t ask) and Paul Longley has a copy but he told me to tell you all to go the Library. UCL Library of course doesn’t even have a hard copy so Paul suggested I email Karen Kemp for the pdf. Lo and behold as soon as they woke up in Hawaii where she is, she sent me a copy of the download – yes the Encyclopaedia is online – so here is the printed download accessed by Karen from Hawaii, taken from the University of Southern California library, emailed to me for the blog. All in a couple of hours. The power of the net. Where will it end?

Introduction to Urban Models

Posted on January 19, 2012 by Michael Batty

The first session comprised an introduction to urban modelling. Essentially this introduced the term model across many different types as well as the model building process. I skipped a number of sections which I would like you to study. If you load the first lecture in the session, then look at the last few slide pages on the relationships between prices and distance and see what you think about how good the fit is. It’s terrible statistically but does it show anything? Think about the limitations of statistical fitting in terms of your intuition about the nature of the relationship. In the second lecture of the session, we skipped the sections 4 and 5 on dynamics and ABM, disaggregation. Have a quick look at these; and don’t forget to read Lowry’s Short Course in Model Design which is a must for this course.

Models Lectures Start Today

Posted on December 20, 2011 by Michael Batty

Five sessions of 2 hours duration each, divided into nine lectures. It will introduce models, the ideas and their relationship to theory, science and practical problem solving. It will begin with spatial interaction, move to integrated land use transport models, & conclude with developments based on agent-based models (ABM) & cellular automata (CA). This is the first of a double header in the MRes lectures on Spatial Modelling & Simulation.
