eLearning in GIS
Beginning with the massively influential NCGIA Core Curriculum Project of the 1980s and continuing through to the current development by UCGIS of its Body of Knowledge, GISc educators have a good record in informal collaboration to share teaching resources. Rather less common have been the sharing of the associated teaching in fully accredited degree and certificate programmes, but this is one area in which being a partner in WUN can make a huge difference. Our pioneer offering is the developing teaching collaboration between Southampton, Leeds and Penn State.
e-Workshop on Spatial Analysis in R

Teach Yourself Spatial Regression Analysis
Regression analysis is applied to spatial data in several ways, from standard analysis of data that happen to be spatial, through regression using spatial co-ordinates (trend surface analysis), to models in which the parameters are allowed to vary over space (geographically weighted regression) or in which spatial dependence is explicitly accounted for. Whatever approach we take, things aren’t simple. At University of Manchester on 20-24th November 2006, Paul Voss of the University of Wisconsin-Madison, together with Susan Ramsay of the University of Manchester, gave a five day course on spatial regression analysis. This they define as:
Regression using spatially aggregated data in which explicit attention is given to the location and arrangement of the geographic units.
The problems that such data involve are:
- Coping with the effects of spatial autocorrelation;
- Avoiding the danger of committing ecological fallacies;
- Understanding the influence of the modifiable areal unit problem and aggregation bias;
- Understanding scale dependency in any results;
- Minimizing boundary effects at the margins of the spaces chosen.
We are pleased to make available a record of these sessions, without the associated practical work, on the WUN/GGISA website in the form of five PDF files:
We have also recorded the second and third days of Paul Voss’s presentations, and these can be accessed at:

Experiences in Online GIS collaboration
David Martin (Southampton) gave an interesting and informative account of ‘Online GIS collaboration’ at the recent WUN Workshop in Chicago on eLearning, which will be of interest to the rest of the WUN Global GISc Academy. In his talk David outlines the history of the collaboration between Southampton, Leeds and Penn. State, the challenges faced and the solutions adopted.
