Today’s Training: Revisiting ArcGIS Online
- Deliverables:
- Share a link to an ArcGIS Online map that showcases some data analysis.
- In a blog post on your portfolio site, reflect on what you worked on and what you were trying to accomplish. How does this map illustrate something about your data? Revisit the questions and struggles from your first pass at using ArcGIS Online: where do things stand now?

In today’s training, I attempted to create a visualization of data from the UK census.
I used the UK government’s National Statistics bureau’s website
to select and filter the data for certain boroughs (counties) in the Greater London area.
I was interested in comparing the types of housing (apartment, caravan, whole house…) and the availability of cars/vehicles in housing units.
After attempting to use the coding feature, I was unable to find an effective way to compare the type of housing and the availability of cars.
Possible reasons that may have led to this challenge were:
1. I gave each data point from the same borough the same longitude and latitude
Since the original dataset contained name of borough for each data (about 165 for each borough), I replaced each name with approximate longitude and latitude.
- this meant the location that each data point corresponded to were not specified.
2. I was comparing qualitative to qualitative (type of housing and description about availability of cars).
The original dataset did not include information about the number of cars (which would be quantitative).
While this was an attempt to use ArcGIS online using real-life census data, I learned the importance of data cleaning and organization before running an analysis. Because I like the ability to visualize the data using a map, I will need to do further research and practice more advanced mapping using this tool.
