I sometimes get myself into Native-Path-adjacent GIS enthusiasms (other than my original projects), two of them in particular being the original path of the Walking Purchase, and the Mason-Dixon Line.
There was very little information I could find about the actual path of the Walking Purchase “walk” — certainly no publicly available GIS data, just a few scanned maps here and there, along with many depressing accounts of the whole sordid incident and its aftermath. This shouldn’t be too surprising; it seems that the perpetrators took steps after the fact to obscure what exactly happened. This information is probably not lost to history, but it is probably well buried, and it seems that not many people like to dig for and play with shameful data from the past.
By contrast, the Mason-Dixon Line is pretty well established online, but then the line itself has been a part of state (and colonial) legal boundaries for more than 250 years, and a cultural boundary (and touchstone) for almost as long. It was a large and highly scientific project for its time, and well marked at the time with massive milestones and a great deal of documentation, and it has had multiple restorations over the centuries. In other words: not shameful, but a point of historic pride. It has received a great deal of attention in recent years, as surveyors and others have been documenting the GPS locations of the original (and replacement) milestones. More info from the Mason & Dixon Line Preservation Partnership can be found here.
Anyway, just some things I’ve been thinking about.
