Blog 5: Georeferencing

 For this map I decided to use one the Sanborn Fire Insurance maps of Columbia, SC from 1910. The process of georeferencing, creating new feature classes, and digitizing buildings is not particularly difficult but definitely time consuming in these learning stages. The block I chose to digitize had an interesting variety of types of builds including; homes, office spaces, general and furniture stores, Coca-Cola factory, printing press, and police headquarters. I did two layouts of the same map with two different fields selected for comparison, one showing a gradient of building types and the other showing number of floors. By showing these two fields I was hoping to see correlation between the types of builds and the number of floors that were average for the time period. To some degree you can see that most homes or dwellings were on average only one floor whereas the larger commercial buildings average between two and three floors. Though I think to  a larger data set should be analyzed to form a full hypothesis.

    The Coca Cola building definitely pops with its deep red! Nice analysis of the floor levels and trends is residential versus commercial buildings.

    The overlay of the historical properties on the modern map is fascinating as large block buildings now dominate the landscape of modern day Columbia. It's really interesting to see how the city has developed over time

Project Update

Image
 I have run into a few issues with content that is available for my project to be able to answer this questions I had hoped to. To begin, I hoped to incorporate the Ground Penetrating Radar survey that indicated enslaved housing, though the problem I have run into is not only the fact that this survey was done in the 1990s but also that the maps the surveyors provided had no real life context to connect the data too. I've included a photo of the type of map that was produced during this survey, this is very disappointing because this information is very important to my project but more importantly to the history of the site.  Given this information I will still try to compare the location of the four known tenant sites to the mansion, I will include historical maps to see which of these homes were mapped throughout the years which will help with understanding of how long these structures were standing. I will include a 1913 soil survey map of Union county, multiple SCDOT maps,...

Project Proposal

 For my final project I would like to examine the placement of tenant homes around the Gist mansion on Rose Hill Plantation in Union, South Carolina. Post emancipation many previously enslaved individuals continued to live and work on the land they were tied to but now as tenant farmers, sharecroppers, and wage laborers. The same was true for Rose Hill Plantation, there are fourteen known tenant farmer homes that were associated with the property, though only four of these house sites have been excavated and have recorded gps points for their location. Another important question regarding this site is, where were the enslaved cabins located? Over the course of 128 years of this plantation being in use, 280 individuals were enslaved on the property. I have found reports of ground penetrating radar being done and locating evidence of structural remains of enslaved housing. I would like to compare this data to current known locations of tenant houses to see if there are similar patter...
