About

Specifications of earth observation images differ among satellites, sensors, and distribution systems, so the hurdles of cross-sectional using of the data are still high. Therefore, we are developing the satellite data distribution service, "JAXA Earth API", which enables developers and researchers to use JAXA's multiple satellite data easily in programming environment such as Python and JavaScript.

Some of the earth observation data published by JAXA are available, and will be added sequentially.

Information

2023/06/01 - QGIS Plugin was joined to the Apps & Tools.

Apps & Tools

  • QGIS Plugin

    Python API is more easily available on the QGIS by using the plugin. (Developed by MIERUNE Inc.)

    Start

  • JavaScript Notebook Samples

    JavaScript API is also available on the Observable.

    Start

  • Sea Level Rise Simulator

    Explore the rise in sea level by using digital surface model "AW3D" data.

    Start

  • Data Explorer

    Explore JAXA Earth datasets by web app developed by using JavaScript API.

    Start

APIs

API that runs on the client side is developed and disclosed, which allows users to check and change the process as needed. The API can acquire metadata of any layer and satellite data of any area and date.

  • API for Python

    API for Python is available! The API has QGIS interface to acquire and display satellite images.

    Get Started

  • API for JavaScript

    API for JavaScript will come soon! By using the API, you can display satellite images on your browers and can develop web apps.

Technologies

COG (Cloud Optimized GeoTIFF)

  • In the database, JAXA Earth API uses COG as satellite image. COG enables users to get optimized tiles to minimize data volume of transfer.
  • If you would like to know more, please check it.

STAC (SpatioTemporal Asset Catalog)

  • To enable efficient search and retrieval of COGs stored as various collections, STAC is employed as a data catalog and stored in a database.
