Information

2023/01/10 - Almost datasets were updated including past data before 2020.
2022/08/16 - JAXA Earth API for Python Version 0.1.2 (Prototype) is available.
2022/06/09 - Prototype of JAXA Earth API has disclosed.

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 and disclosed the satellite data distribution service, “JAXA Earth API”, which enables us to use JAXA's multiple satellite data immediately and intuitively.

Datasets

The datasets includes JAXA's public datasets and other agency's public datasets converted to COG (Cloud Optimized GeoTIFF), and so on. Over 70 datasets are available!

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.

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.
