Our guest speakers covered various topics related to wrangling public data, including techniques for handling geospatial images, writing faster queries, and using open data to monitor COVID-19 and climate change. The first session of DataPub, a new monthly meetup focused on open data, was hosted online, allowing more people to join and share diverse perspectives. Guest speakers Joel Natividad, Saheel Ahmed, and Jonan Scheffler shared their experiences with wrangling public datasets, including using satellite imagery for environmental monitoring and optimizing geoTIFFs for faster queries. The event aimed to help community members find great public datasets, better interpret results, and use open data to drive positive change.
