The main motivation of the workshop is to celebrate Pete Fisher’s professional life which had 3 strong foci: research, publication and education. As well as reflecting on his contribution we would also like to use some of his ideas to help us consider our progress in the discipline of GIScience and where we go next.

In his research, Pete's central concern was the disconnect between the "thing" (the object, behaviour or process) and how we represent it. Consideration of the nature of the pixel and location of geographic features led him into interesting areas, including geoslavery (whose voice matters), uncertainty and fuzzy sets (what are the characteristics of the thing) and conceptualisation (how do we represent space and place). Pete posed some big questions; ten years ago he asked Where is Helvellyn? are we any closer to an answer?

As editor of IGJIS Pete oversaw the transition from GISystem to GIScience. One of the workshop aims is to consider the degree to which GIScience continues to progress and innovate.

As an educator he was a mentor to many, an excellent teacher and he was intensely interested in concepts and principles. Important questions are being raised as other disciplines are reinventing 'digital geography' all around us: what should the GI academic community be teaching, how, when and to whom? Do we need GI courses? Are we being side-lined? If so, do we need to admit it and re-think GI education?

Finally, the only well-known law in geography is Tobler’s “Everything is related to everything else, but near things are more related than distant things” and Arbia and Espa’s less well known corollary para-phrased as “things looked at a coarse scale seem more similar than when looked at a fine scale”. Maybe, we shouldn’t exhibit 'physics envy’ and dream of laws, but, is it possible to identify some principles that are in the spirit of Pete's contributions to GIScience. 

We invite everyone to come up with principles based on Pete's work. We hope your contributions will act as a focus for discussion throughout the two days and perhaps we will end up with something substantive. There are processes that will help this work; some may involve beer.
