Information
This map was created with publicly available data and uses ArcGIS Javascript API to render the data. Updates to the function of the map as I am using it to learn more about the ArcGIS Javascript API.
The goal of the map is to show COVID-19 positive rates along with the race/Hispanic data and ballot drop box locations and their status in Alameda County.
Data Sources
- Census tract data is 5 year American Community Service ACS data from the US Census Bureau from 2018 table B03002. The feature service description is located here. It is symbolized to show the predominant race/hispanic for each tract, the level of that predominance, and the total population in the tract.
- COVID-19 positivity rate data is provided by Alameda County by zip code. The data is provided here and can be downloaded or displayed using the provided API.
- Ballot drop box data is provided by Alameda County. The data is in 2 locations as the county has a Google Map showing the location of installed drop boxes here and a list of proposed is no longer available. The feature service is created from that data and I have published it here. I will update the installed list as the data changes. Last update (11/02/2020).
