Practicum 1

For my geo-referenced project I used an image of Pompeii dated from 1832. The map details the archeological sight from what was currently found during the 1800s and 30s. The geo reference tool allows me to focus on a particular section of the map thus, allowing me to learn more and provide detail information on the area.

In terms of the course, large population centers are better mapped out with heat maps, strata maps, and anything requiring data.

Practicum 2

Success!

1.) For practicum 2: I successfully geo referenced a map of the second day’s battle of Gettysburg. In terms of using the geo referenced image as a guide; it will be easier to view and see where key events of the battle occurred. As such, helping Historians and Archeologists to accurately map out locations of these events and designate certain areas of historical and archeological significance.

2.) It depends on what type of map you use to geo reference. Some Google Maps aren’t useful due to using modern locations for historic events. Like what I have found with my project on the Salem Witch Trials, using modern maps and geo referencing might not be the best approach to use. Due to locations changing overtime and the lack of knowledge of where key people lived during the trials.

Practicum 5- Philadelphia Red Lining

  1. I think looking at this map with the Berean (Red) and Metlife (Yellow) loans with Berean loaning out to black populations and MetLife more toward white populations. The green sectors are based off of percentage black population so with more Berean loans in darker sectors we can make this observation.

2. Regions that were identified as high-risk had the highest interest rates. On top of that areas that had the highest black populations also suffered the highest interest rates.

3. HOLC maps dictated mostly where Berean could give out loans being mostly in high-risk areas (red). These areas also had the highest percentages of black populations whereas the low-risk areas (blue and green) had the lowest percentages of black populations.

4. An additional data layer I would be interested to see is dwellings that have house covenants in the Philadelphia area. If there were areas with housing covenants I would expect them to be on the north side of Philadelphia away from the “high-risk” areas.

5. My map below consists of the Berean (pink) and Metlife (blue) loans, the 1950 census tract showing percentage of black population as well as the high risk areas determined by the HOLC map. I believe these three layers effectively show how the HOLC map determined where black and white populations lived in Philadelphia by showing the Metlife loans being away from high-risk areas and in areas with lower black populations as well as how Berean loans were almost restricted to these high risk areas in larger black communities.

Practicum 6

Thinking of the Sanborn fire maps I’ve been working with it could be useful to know how far fire hydrants are from buildings that could be susceptible to fires. So I think it could be done in a way where it shows buildings that are made out of wood or flammable materials and their distance from fire hydrants. It could highlight the need for hydrants in certain areas and could be farther away from areas with say stone or brick buildings. For me I thought of doing these with residential buildings and how many there are in relation to churches and other identified community centers to show the importance of these buildings as community anchors.

Dust Bowl ArcGIS Practicums

This practicum observed the change of the plains region’s cultivated land or more so the overworking of the the Great Plains that created conditions leading to the dustbowl.

1880 TotalCult/Area

The glaring observation of this first map is that Oklahoma shows no data. This is because as of 1880 Oklahoma had not been added to the union. However looking at states with data we can see that Kansas led the region in cultivated land being a large wheat producer.

1900 TotalCult/Area

As we move into 1900 we can see land cultivation start to creep westward into Colorado and parts of West Texas. We can also see that land that was already cultivated become even more used.

1940 TotalCult/Area

By 1940 we can see the over-cultivation of land had spread throughout the plains region and altered every state’s arable land area. We can also see more counties where they had been moderately cultivated, fall deeper into cultivation.

While the 1940s were around half a decade after the Dustbowl, we can see how there was a mass of over-cultivated land that deprived soil of hydration and protection allowing for drought to tear through torn-up farmland and blow the plains into a dust bowl.

  • The 1960s were the period in which White Flight was at an all-time high. More black people started to move into North Omaha during this period and built/moved into black suburban neighborhoods. The black middle class was created during this period, most of these neighborhoods clustered around what would later become the area of the North Freeway. This is the decade Eisenhower passed his Highway and Interstate Act and the decade Omaha started planning the North Freeway.

(I would like to also mention NOISE Omaha, which has a huge list of resources for redlining including many static maps: https://www.noiseomaha.com/resources/2019/7/12/redlining-resources. Also, Adam Sasse and the Freeway Study have multiple maps throughout the readings, specific to Omaha. These show the old businesses, schools, and other community centers destroyed. The Freeway Study has been a detrimental resource during my research, especially considering both the cultural context and the sheer number of maps and data strewn throughout the document.)

Blog Post- The Ethical Implications of Mapping History

The period of American History ranging from 1877 to 1968 was a violent and politically charged time in our nation’s history. Following the end of the civil war, the plan of Reconstruction under Andrew Johnson fell of from Lincoln’s inital plan and failed to properly address racial tensions in the south. Following the emancipation of former slaves, African Americans were able to practice their constitutional right of voting for the canidates of their choice. At the same time however, white suprimacist across the south began to form groups to fight against this right. One of their many acts aganst African Amricans was voter intemination done to prevent racial and ethnic minorites from voting across the south.

One of the many violent acts these groups commited was a practice called lynching. During the period of Reconstruction, lynching was used as a common tactic by the KKK to scare and prevent African Americans from going out and voting. This map titled “Racial Terror Lynchings” from the article titiled “Racism in the Machine: Visulization Ethics in Digital Humanities Projects.” This resource gives an insightful overview of the violence and persecution African Americans faced across the south from the years of 1877 to 1950. The map allows you to find specific data on a state or region where lynchings occured during this period. From the evidence presented on the map, we can see that ynchings were more common in the “deep south” Alabam, Missippi, Louisiana, and Georgia. We know from historical records that groups such as the KKK had more influence in the “deep south” than anywhere else in the country. However, the map also shows that lynching wasn’t excluively done by white supremacist groups rather, it transitioned during the period of Jim Crow.

With the end of Reconstruction in 1877, governments across the south began to from laws that actively kept African American excluded from regular society. These laws would become known as the “Jim Crow Laws” and would be enforced across the south well into the 1960s. During this time, African Americans became targets of racial mob violence during periods of political turmoil and when an African American faced a trial for a crime against a white person. During particularly violent racial riots enitre African American communities were detroyed and its people displaced. Lynching (as seen in the map above) was used by whites to excute African Americans they viewed guilty.

What I really liked about the article provided in the course syllabus was it showed how widespread these riots were. Often, in history class in high school we are taught that racial violence was only occuring in the south and nowehere else in the United States. I can understand why… considering you can cover so much in a high school hitory class. However, it gives an incomplete picture of the reality of the United States during this period of violence and tension. Racial violence in the West Coast of the United States is often overlooked/not discussed as much when we discuss this period of United States History. (As the above map on the right shows) mob violence against ethnic groups ocured in major cities across California and the Western United States. One of the tensions in the west coast was the increasing number of immigrants arriving from the east. White suprimacist and “natavist” groups attacked these immigrants which is presenetd on the map.

A story that is often overlooked during this time period was a form of resistance by an African American during the time of Jim Crow. His name was Monroe Nathan Work who during his time in Savannah, Georgia, witnessed the first segregation laws passed during Jim Crow. While living in Savannah he woud marry a school teacher named Florence Hendrickson, together they would work together in documenting lynching, documenting lack of resources in African American school, sgregation in their community, and pushed for better living conditions for African Americans. Together the two of them would create a program called “Nego Health Week” which was designed to promote healthy living in African Amercian comunities.

Sam Ellerbeck Blog Post 8: Mapping & Ethics

Monroe Work Today’s “Map of White Supremacy Mob Violence” and the Equal Justice Initiative’s map “Lynching in America” are both very powerful depictions of historical racial violence in the form of lynching, but the maps differ heavily in their intended messages. Monroe Work Today portrays the United States’ occurrences of lynching as a widespread issue that has affected all people and geographic locations, whereas the EJI has a much more narrow lens, connecting past lynchings of African Americans to the structural issues that persist today.


The map from Monroe Work Today uses points to represent the lynchings that have occurred in America based on location. Additionally, each point includes information in regard to the lynching event, such as the individual’s name, race, and some background and sources that help provide context. In doing so, the map argues that lynching was a violent act faced by people of various races and ethnicities.

Map of White Supremacy Mob Violence, Monroe Work Today [1]

Just as important to its argument, however, is that the focal point of the map is very broad, encompassing the entirety of the United States (with the exception of Alaska and Hawaii), and it emphasizes the great length of history in which lynching has been an issue. In doing so, it makes the case that racial violence in the form of lynching has persisted as a very widespread and prolonged American issue. Lynching is not necessarily unique to one particular people, place, or time.


The EJI’s “Lynching in America” makes a different argument. It uses a choropleth style to tally the lynchings of African Americans by county across the United States. In excluding the lynchings of other races and ethnicities, the map particularly highlights the continual violence and injustice against African American populations, where it calls attention to the structural forces that have perpetuated this into the present day.

Lynching in America, the Equal Justice Initiative [2]

In contrast to the first map, the EJI’s map focuses solely on lynchings of African Americans, particularly in southern states, which are centered spatially on the webpage. Also, the timeframe is relatively obscure, and there is no background information regarding each lynching displayed. In doing these things, the map brings structural violence against African Americans collectively to the foreground, narrowing the scope of the mapping significantly and opposing Monroe Work Today’s more all-inclusive approach.


In considering the ethical implications of mapping, Monroe Work Today does a much better job of acknowledging the victim of each lynching as an individual. In recognizing humanity and the historical wrongdoing of lynching, the map more ethically portrays that “the individual deaths are of greater significance than the [geopolitical] boundaries” in which they occurred []. The EJI falls short in this aspect – in using a choropleth map and making each individual event more obscure, it portrays the lynchings of African Americans simply as data and not much else.

Map of White Supremacy Mob Violence FAQ, Monroe Work Today [1]

Monroe Work Today also acknowledges the difficulties in the ethical decisions of mapping such information by providing a list of additional relevant discussion. Topics such weighing what is considered lynching, the inclusion of particular ethnicities, and even the challenges of collecting and analyzing the sometimes hard-to-find records are all mentioned. It seems to set a good example in considering a wide variety of ethical implications while describing the challenges of retaining dignity when mapping victims of racial violence.

Lastly, while it holds a sort of symbolic notoriety in American history, lynching was not the extent of racialized violence and marginalization that minority populations faced over time [3]. For ethical considerations, it would be important to bring attention to any profound details as such that a particular map may not be able to fully represent.
