Figure 3. Alignment of a Gangland map of the 1920s with Tiger files of today and the Burgess model of Figure 1, all superimposed as layers in Google Earth which permits the easy stretching of scanned images to fit the underlying Google Earth globe. |
Figure 4. Insertion of flat Gangland map in Google Earth, aligned to underlying features, using the concept of "gores" or small sections reducing error in fit. |
Figure 5. Alignment of the Burgess model with the Gangland map and therefore with Google Earth and associated Tiger files. |
