This is a unified COVID-19 dataset to fulfill the following objectives:
- Mapping all geospatial units globally into a unique standardized ID.
- Standardizing administrative names and codes at all levels.
- Standardizing dates, data types, and formats.
- Unifying variable names, types, and categories.
- Merging data from all credible sources at all levels.
- Cleaning the data and fixing confusing entries.
- Integrating hydrometeorological variables at all levels.
- Integrating population-weighted hydrometeorological variables.
- Integrating air quality, comorbidities, WorldPop, and other static data.
- Integrating policy data from Oxford government response tracker.
- Integrating an augmented version from all sources (future releases).
- Optimizing the data for machine learning applications.
Note that COVID-19 data for some European countries from Johns Hopkins University (JHU) Center for Systems Science and Engineering (CSSE) are reported in the global daily reports at province level, which will be replaced by higher-resolution data at NUTS 0-3 levels.
