    Challenge Description

    Create an app that displays the gravity force for any location on Earth. Grab data about gravity around the world on a gravity map, or geoid, and use positioning data to show gravity at any location. You also could add information about the GOCE mission or other missions, and extend the capabilities to include magnetic field data from the SWARM mission.


    The geoid is a smooth but highly irregular surface that corresponds not to the actual surface of the Earth's crust, but to a surface which can only be known through extensive gravitational measurements and calculations. Missions such as GRACE and GOCE have measured gravitation from Space and allow a precise description of the geoid, or in other words: produce a gravity map of Earth. Recently the SWARM mission has been launched to also map the magnetic field around our Earth.

    Solution Ideas

    Here are some ways for you to frame this solution:

    • - User specifies a location on Earth
    • - Mobile app or web app displays the gravitational field at that location
    • - You can show variations in gravity based on the location of the moon on a specific date and time.
    • - Use positioning data to show local gravity force
    • - Options: show gravity or gravity maps of other planets, maybe in comparison to Earth’s gravity

    • isac2014australiacanberragroup

      The aim of the project is to provide users worldwide with access to accurate gravity data at any specified location on Earth via a highly functional web application. Mission data from ESA’s Gravity field and steady-state Ocean Circulation Explorer (GOCE) was utilised in order to provide users ... Visit Project

    • Crowdvity

      The aim of this project is to combine gravity data from space missions, like GOCE and GRACE, with crowdsourcing data from smartphones. Users will be able to both see the gravity measured by the space missions and send their own measurements to create a crowdsourcing gravity map. The project co... Visit Project

    • Gravity

      This project aims to create online map of the gravity of a given position on a map. The input can be either inputted in numeric format as longitude and latitude or chosen from a pin on a map. The output will be in numeric format, representing the gravitational field at the given point. In th... Visit Project

    • Gravity Bird

      How it works: The user searches for a location on Earth (a city, for example); The map will show that location and it's Geoid height measurement in relation to the corresponding location on the "ellipsoidal idealized Earth". The height of the geoid above the WGS84 ellipsoid measurement ... Visit Project
