[Earth Observe Citizen] Interactive imagery platform for Earth inhabitants to understand our planet.

This project is solving the Image-ine Earth Yesterday and Today challenge.



What would you build if you had instantaneous imagery data of the Earth from the past decade? Using openly accessible access to Earth imagery from the past and present create new ways to interact with NASA’s Earth imagery.


Earth Observe Citizen

Earth Observe Citizen (Earthobs) is an interactive imagery platform that enables Earth inhabitants to explore and contribute to the understanding of our own planet. Users can browse through various types of imagery data, given specific location and time inputs. More interactive features include:

  • Still image capture

  • GIF image generator for time-lapse visualization

  • Side-by-side comparison of images from different time periods

  • Users are invited to find and evaluate the causes of any environmental change observed on Earth, considering several factors. A report could be created using the available tool.

  • Any data produced by the user could be easily shared on social networks for further discussion and comments. The community can provide more information about the event observed, including ground-based photos, videos and stories.

  • Crowdsourced data from the community could be produced and compared to other sources for reference. Example: Weather forecasts, predictions of hurricane track, natural disasters.
