The Stanford Digital Forma Urbis Romae project is looking to piece together a map of Rome created in 203. The map was carved on stone and measured 18 x 13 metres. Unfortunately, most of the pieces of the map are missing, making it difficult to piece together the remaining pieces. Using a number of computer algorithms, the project team has had some success in assembling the existing 1,186 pieces. All of the pieces are indexed and scanned and all of this information is available on the project website, including 3 dimensional images of the pieces.
