4 - Mapping COVID-19
Let's get started
- Open QGIS and create a new project
Download dataset from: https://github.com/maiuchi/ASA_GIS/tree/master
- Save your project to the map folder: name it as gis_demo
- Click "Code" button and select download ZIP
- Data folder structure
- tabular (save tabular data here)
- maps (save project files and maps here)
- vector (save shapefiles here)
- org (original datasets)
- This is how I organize my GIS data for any project. You do not have to have the same file structure, but be sure to keep them in order and neatly!
- Load COVID-19 dataset (covid_selected_CLN.csv) - drag from the Browser panel
Load census boundary shapefile (census_county.shp)
Check Attribute table
- Stuck? Check here!
- I cleaned the modified the dataset as NYC and some counties in Missouri had a different spatial unit from counties. Also, unknown data were omitted.
When you prepare/ clean spatial dataset, please be extra careful about it. Always check meta data and/ or data dictionary.
- I took data from NYC DOH and combined it to the NYT data, because five boroughs in NYC were classified as one county.
Mask Wearing Survey
- Load mask wearing survey data (mask-use-by-county.csv)
- Check Attribute table
