Spacial Maps

In class, we have been talking about the difference between maps and “Spacial Maps”. Essentially, Spacial maps are not your ordinary 2D map but instead have many different layers to it. Spacial Maps can be interactive and show such things as, how many people migrated to an area at a certain time, the distance that a herd of animals traveled, or even where a photograph was taken. In an article by  Jenna Hammerich that we read in class, she talks about how this technology can answer historical questions  such as  “Why did African American families settle almost exclusively on the near north side of St. Louis in the 1940s?”. Below is a link to an example of a Spacial Map made by the Humanities Team at Standford:

I used the website to create my own spacial maps using the Cushman Collection data set.

This is one map that I created. The “dots” are all based off of a data set and represent where each photograph was taken.  To make this map, I simply uploaded the data set and added the layers of geocoordinates and land.

In the map above (I know it is a little blurry that’s how my screenshots kept coming out whenever I saved them) I used the “size point” future on the dots instead. With the size point feature, the dots appear larger where more photographs are documented. I also changed the view of the map to ‘streets’ so that I could see actual state / city names instead of just land. Large dots appear frequently in California so I can learn that a majority of the photos in the Cushman Collection were taken on the West coast of the United States.

Taking it a step further, I focused in on the map in California so I could see which cities actually had the most documented photos. From this, I was able to see that there were a lot of photos scattered along the Bay such as San Francisco and Oakland. However, Salinas, Fresno, and Los Angeles had the largest dot sizes telling me that those cities individually had a lot of photographs taken there.

This map, that I found on is a economic activity map. This map is very similar to the Spacial maps that we have gone over. It has a legend in accordance with colors that shows where in the south there were farmers, forests, manufacturing and trade, livestock, fishing, mining, and places of no activity.
