Data Access and Visualization

Welcome to this practical and analytics-focused episode of the NASA Live Video Podcast: "Data Access and Visualization." ​In this episode, we bridge the gap between raw Earth observation datasets and actionable scientific insight. As satellite constellations continuously generate petabytes of high-resolution Earth science data, mastering the tools and workflows needed to discover, access, subset, and visualize this information is vital for researchers, policy analysts, and spatial scientists worldwide. ​We explore the end-to-end data pipeline utilized across NASA's Earth Observing System Data and Information System (EOSDIS) and Distributed Active Archive Centers (DAACs). Learn how to efficiently query and retrieve geospatial data using platforms like Earthdata Search, Giovanni, and Worldview. Furthermore, we demonstrate hands-on techniques for visualizing multidimensional scientific formats (such as NetCDF-4, HDF5, and Cloud-Optimized GeoTIFFs) using open-source GIS tools and Python frameworks like Xarray, Matplotlib, and QGIS to build intuitive geospatial maps and time-series analyses. ​Whether you are a GIS specialist, an environmental data analyst, a remote sensing researcher, or a space enthusiast eager to learn how to unlock and visualize NASA's open-access climate and Earth data, this episode provides essential technical guidance.
