Map Projections in the History of Cartography
In this paper, we expand application of our mathematical methods for translating ancient coordinates from the classical Geography by Claudius Ptolemy into modern coordinates from India and Arabia to Britain and Ire-land, historically important islands on the periphery of the ancient Roman Empire. The methods include trian-gulation and flocking with subsequent Bayesian correction. The results of our work can be conveniently visu-alized in modern GIS tools, such as ArcGIS, QGIS, and Google Earth. The enhancements we have made in-clude a novel technique for handling tentatively identified points. We compare the precision of reconstruction achieved for Ptolemy's Britain and Ireland with the precisions that we had computed earlier for his India be-fore the Ganges and three provinces of Arabia. We also provide improved validation and comparison amongst the methods applied. We compare our results with the prior work, while utilizing knowledge from such im-portant ancient sources as the Antonine Itinerary, Tabula Peutingeriana, and the Ravenna Cosmography. The new digital reconstruction of Claudius Ptolemy's Britain and Ireland presented in this paper, along with the accompanying linguistic analysis of ancient toponyms, contributes to improvement of understanding of our cultural cartographic heritage by making it easier to study the ancient world using the popular and accessible GIS programs.

Computer Consultant and Technical Writer
Dr. Anthony Durham spent 15 years as a research scientist, working on the physical chemistry of plant virus proteins and then on ion flows, especially calcium, across membranes. He then spent another 25 years running a computer software business, with a particular focus on the use of vector outlines in the sign industry. Dr. Durham currently studies the geography of Roman Britain and the ancient place names.
