NASA EARTH OBSERVATION DATA
NASA collects Earth
observation data (https://science.nasa.gov/earth-science) from satellites, instruments on the International Space Station, airplanes,
balloons, ships and on land ESD researchers collect data about the science of our planet’s atmospheric motion and composition; land
cover, land use and vegetation; ocean currents, temperatures and upper-ocean life; and ice on land and sea.

NASA's Earth observations are freely accessible to all, including NASA’s many partners in the U.S. and international organizations
and governments, disaster-relief agencies worldwide, scientists from academia and the private sector, business, the military, and the
general public.
NASA has over 27 petabytes of accessible Earth science data and over 12,500 unique data products. NASA's Earth Science Data
System program seeks to maximize the return on NASA's datasets.

GOOGLE EARTH ENGINE
Google Earth Engine combines a multi-petabyte catalog of satellite imagery and geospatial datasets with planetary-scale analysis
capabilities and makes it available for scientists, researchers, and developers to detect changes, map trends, and quantify differences
on the Earth's surface.
Earth Engine is a platform for scientific analysis and visualization of geospatial datasets, for academic, non-profit, business and
government users.
Earth Engine hosts satellite imagery and stores it in a public data archive that includes historical earth images going back more than
forty years. The images, ingested on a daily basis, are then made available for global-scale data mining.
Earth Engine also provides APIs and other tools to enable the analysis of large datasets.

PUBLIC-PRIVATE PARTNERSHIP
The NASA and Google Earth Engine (GEE) teams are collaborating together under an existing public-private partnership to achieve
greater data access, availability and attribution of  NASA data holdings on the GEE platform.
The collaboration will help support NASA in its efforts to maintain and improve data availability and accessibility to all users in
compliance with the NASA open data policy, and Google’s efforts to advance the utility of the Google Earth Engine platform to the
scientific community.

NASA DATA IN GEE
There are over 80 NASA Earth science datasets (https://developers.google.com/earth-engine/datasets/tags/nasa) currently available
in Google Earth Engine. These include a number of MODIS datasets (such as the Terra Land Surface Temperature and Emissivity
Daily Global 1km dataset shown above), ocean color data and gravitational anomaly data. A breakdown of NASA's datasets in GEE
by scientific theme is shown below.

NEXT STEPS
Improving accessibility to and attribution of NASA data for all users in compliance with NASA’s open data policy
Documenting NASA Earth science community use cases which leverage the GEE platform to meet Google's goal of advancing the
utility of the platform for the scientific community.

ABSTRACT
NASA’s Earth Science Division (ESD) seeks to advance knowledge of Earth as a system in order to meet the challenges of
environmental change and to improve life on our planet. ESD achieves this goal by collecting Earth observations from satellites,
airplanes, balloons and the ground for almost all areas of the Earth. The datasets created from these heterogeneous observations are
freely and openly available to all, including NASA’s partners such as U.S. and international organizations and governments,
disaster-relief agencies worldwide, scientists from academia and the private sector, business, the military, and the general public.
NASA has been collaborating with Google Earth Engine (GEE) under the existing umbrella of the NASA and Google public-private
partnership to promote each organization’s shared goal of making Earth observation data accessible and useful. The NASA and
Google Earth Engine teams are working together to develop a set of best practices that will support NASA’s goal of improving data
availability and accessibility to all users and will aid in Google’s efforts to advance the utility of the Google Earth Engine platform
to the scientific community. This talk will highlight the NASA and Google Earth Engine collaboration to date and will share lessons
learned that may be useful to others considering similar partnerships.
