Assessment Maps and Chart


For this week's blog post we were asked to recreate our Assessment maps from Thursday's class.

The maps required:
1. Counties color-coded by 1942 collegiate football conference and the boundary of each conference. Label each conference on your map. Do not include the original map.
2. The number of conferences within 100 miles (Statue Miles) of each county. Include the conference boundaries.
3. The 1940 population by county for only the counties within 50 miles of a collegiate conference. Include the conference boundaries.


My first map I georeferenced the map provided and then used polygons to create the boarders of each conference. I think spatial joined the conferences (and names) to the counties layer. This allowed me to run a "select by location" which I intersected the boundaries and counties, which allowed me to color coordinate the conferences.


The second map required me to find how many conferences were within 100 miles of all the counties. To do this I ran a spatial join and changed the "intersect" option to "within a distance" of 100 statute miles. This allowed me to use symbology, using a graduated color map to depict the locations with 0, 1, 2, and 3 conferences within 100 miles.


For my final map I joined the population excel sheet to the counties layer in order to look at population by county. I think ran another spatial join but changed the distance to 50 miles. From there I did a definition query to remove counties not within 50 miles of a conference. From there I used graduated colors to show the population within the 50 mile buffer.

Lastly, for the bonus it asked us to create a chart comparing the total population in each collegiate conference. To do this I need to do a spatial join to the conference boundaries, using the population and changing the filter so it would provide the total sum within each boundary. Below is the chart.

Portland, Oregon HOLC Redlining Dataset And 2010 Census Dataset Map

Portland, Oregon HOLC Redlining Dataset And 2010 Census Dataset Map Map A. Layered combination of redline grade in1940 and 2010 census data on the overall percentage of black households. Map B. Just the 2010 census data on the overall percentage of black households. Map C. Layered combination of redline grade in1940 and 2010 census data on the overall percentage of black households (but showing legend w/ black household percentage).  Map D. Oregon Census 2020 - Black population percentage For my map I explored Portland, Oregon (West Coast Best Coast!) and looked at the racial demographics for black households in the city. I also decided to look at the Oregon 2020 census to compare where the black population resides a decade after the 2010 census date. While population and households are not interchangeable it provided an intriguing experience and prompted me to ask about how the population has shifted and wonder if that would change the household information.  1)  ...

Cartographic Creations - Arctic Sea Ice Decline

Image
This was an extremely helpful exercise to learn some of the really cool and interesting things that can be done in ArcGIS Pro. I don't know if I will remember everything, but I learned a lot.  Part 1 asked us to Map Arctic Sea Ice (Map 1). I added the five elements discussed in class (Title, North Arrow, Legend, Scale, and credits) which will be seen in Maps 1, 2, and 3. Maps 4 and 5 do not have all five elements due to me following the tutorials directions to make sure my final product matched. Map 1 Part 2 asked us to refine symbology which is depicted in Map 2. Map 2 Part 3 asked us to label the map which is depicted in Map 3. Map 3 Part 4 asked us to arrange a map layout which is depicted in Map 4. Map 4 Lastly, part 5 had us make an inert map and finalize the presentation, which is depicted on Map 5. Map 5 This final product looks polished and ready for print. This tutorial explained the many different ways ArcGIS will allow us to portray maps and information, making it pleas...

Radios in 1930 and 1940

Image
  The data sets I chose for this week’s blog were Population by Race (1920, 1930, 1940), Total Population, Race, and Total Families Reporting Radios. Choosing the data sets this week was challenging. I tried looking at farm value or farm equipment based off race or population but had difficulty getting a map that accurately depicted what I was trying to determine. After messing around with a bunch of different data set options I decided to use the family radio data set as a base and look at how that changed based off race.  Map 1: 1930 Radios / Population Map 2: 1930 Non-White/Population Map 3: Radios / Non-White Population It was extremely interesting to me to see that the majority of “non-white” Americans resided in the south but almost all the “non-white” families that owned radios were in the north. Meaning first off there were not many non-white families that owned radios but that the areas they were most populated still didn’t have many radios at all. That had me asking,...
