Data Science at Scale: Harmonized Landsat Sentinel (HLS) Case Study
Most people associate data science as the process of extracting knowledge and insights from data. While that is partly true, data science is a broader concept involving data collection, storage, integration, analysis, inference, communication, and ethics. Gaining a good grasp of these concepts is essential for anyone working in a data-rich field such as Earth Science and Remote Sensing.
This summer school session will explain the complexity of the data life cycle, the supporting data and analytical systems, and the research life cycle. Workshop participants will get a "behind the curtain" view of science data production at scale using the Harmonized Landsat Sentinel (HLS) data as a case study. The workshop will explain the challenges of designing and implementing large-scale processing pipelines on the cloud. A supporting cloud-native analytical platform to enable interactive analysis and visualization will be covered. The participants will perform hands-on scientific research using the cloud-based data and analytic framework.
