GIS Day 2020
Expanding understanding of Earth science.

Geographic Information Systems (GIS) is a standardized data framework that allows for gathering, analyzing, and visualizing geographic data of all types. November 18 is GIS Day 2020—a day to celebrate GIS technology!
NASA uses GIS to aid in managing, understanding, and sharing Earth observations. GIS goes beyond mapping by providing powerful capabilities to visualize, analyze, and interact with big data. Want to learn more? View the story map on how and why GIS is utilized as well as explore a few highlights of GIS applications at NASA Earth science.

GIS Applications at NASA Earth Science
The Worldview tool from NASA's Earth Observing System Data and Information System (EOSDIS) provides the capability to interactively browse over 900 global, full-resolution satellite imagery layers and then download the underlying data. These services are also being made available through Esri's Living Atlas of the World, a global collection of geographic content.
Explore NASA oceanographic data through State of the Ocean, an interactive tool that promotes discovery and analysis of oceans through interactive maps, animations and plots. The suite of tools provide access to a broad range of satellite-derived products and key parameters of interest to the oceanographic community.
New to NASA data? Explore NASA geospatial content and even build your own maps using NASA's data online. NASA ArcGIS Online (AGOL) provides the capability to create and share NASA Earth science data with the public and interagency partners by bringing data to end users in an easy to use, cloud-based web platform.
In an unprecedented collaboration, three space agencies have created the joint COVID-19 Earth Observation Dashboard, integrating multiple satellite data records with analytical tools to allow tracking of changes in air and water quality, climate change, economic activity, and agriculture. NASA's Socioeconomic Data and Applications Center (SEDAC) also created a COVID-19 global viewer with population estimates by age group and sex.
Explore NASA's Prediction of Worldwide Energy Resources (POWER) viewer and web services, providing solar insolation and meteorological data subsetting, charting, and visualization tools for renewable energy in an easy-to-use interface.
NASA's Alaska Satellite Facility Distributed Active Archive Center (ASF DAAC) offers on-demand Sentinel-1 Radiometrically Terrain-Correct (RTC) datasets in ASF DAAC’s Vertex Data Search portal. This makes analysis-ready synthetic aperture radar (SAR) data available to anyone, and the updated ArcGIS toolbox is optimized for use with these products. For additional information, view the RTC on Demand Story Map.
The Disasters Applications area promotes the use of Earth observations to improve prediction of, preparation for, response to, and recovery from natural and technological disasters. View the latest products and information on NASA's Disasters Mapping Portal.
If you want to use GIS to visualize and analyze remote sensing data, check out training available with NASA's Applied Remote Sensing Training (ARSET).
Explore NASA Earthdata as an authoritative ArcGIS Image Service Provider at the Living Atlas Earth Observation Explorer. The Earth Observation Explorer app provides different bands of Sentinel-2 and Landsat to better explore the planet's geology, vegetation, agriculture, and cities. Additionally, it provides access the Sentinel-2 and Landsat archives to visualize how the Earth's surface has changed over time.
