Spatial Analysis II

For this practicum, we were instructed to overlay maps, either historical or informational maps, using MapWarper. I found a map of the Minnesota Territory from 1849 and compared it with a map of the state of Minnesota as it looks today. I found it interesting that the 1849 map still contained some native names for lakes and rivers and sacred places, something that is not done today as most of the names have been changed. The map from 1849 did not warp too much when it came time to overlay it on the map from 2020, most of the lakes and rivers maintain similar shapes to this day. Unfortunately, I was unable to embed the georeferenced map, and the screenshots that I included in this blog don’t provide the level of detail that the original map contains. In regards to my project, I might do something similar to this for my final project, possibly so that I could see how tribal land has shifted and changed over the years.

One thought on “Spatial Analysis II

  • If you wanted to replicate this exercise for the final project, I wouldn’t recommend embedding the historical map itself, but simply “tracing” polygons or point from the historical map to make a new shapefile layer. Does that make sense? Its actually not a difficult process, but it would be easier to explain via zoom. Bring your ideas for the mapping portion of the final project to our discussion next week!
