Sixteen 1:2000 topographical maps from the Greek Geodetic Survey have been digitized to create the topographical foundation for the immediate area of Roman Corinth, roughly 35 square kilometers. The topographical maps include information such as modern roads, paths, ledges, property lines, field lines, houses, as well as topographical contours. It has been noted, for instance, that several modern village roads still have as their orientation the Roman roads of the colony (Fig. 1).
In addition some modern house and lot lines still respect the ancient Roman insulae and, in the areas surrounding the city, it has been noted that aspects of the modern field boundaries still reflect vestiges of the ancient Roman land division, with some lots retaining the original colonial orientation as well as maintaining widths of 1 Roman actus of 120 Roman feet (Fig. 2).
From the contour lines of the topographical maps it has been possible to utilize other engineering and GIS programs to create digital terrain models of aspects of the site, general three dimensional computer images of the landscape as well as to run three dimensional GIS functions.
