The rest is history. I dipped my toe in philosophy, I gathered material on spatial and temporal representation from many disciplines outside geography and informatics, and four years went by while I developed the new outline. I eventually began writing again in earnest in the summer of 1999 and I finished the manuscript in July 2000. Over its five years of development, this book has been written in a variety of places with help from many different people. During my 1995 sabbatical, I wrote substantial parts of the book at the Environmental Spatial Analysis Group (GASA) in the New University of Lisbon, and at the US National Center for Geographic Information and Analysis (NCGIA) in Santa Barbara. I would therefore like to thank Antonio Câmara of GASA and Mike Goodchild of NCGIA for their hospitality and support. I also wrote parts of the book at the Palacky University of Olomouc in the Czech Republic, at GISDATA conferences in Rostock, Nafplion and Strasbourg, at the NCGIA Initiative 21 meeting in San Antonio, at the NCGIA Varenius initiative on Discovering Geographic Knowledge and backstage at the Theatre on the Bay in Cape Town! Fittingly, given the location of the case studies in part II, some of the book has even been written in the Hut on Scolt Head Island!
