In order to improve the usability of Tellus, we are planning to update the APIs for data distribution, and the Cloud Optimized GeoTIFF (COG) format for reference data. This may change the access method of satellite data provided by Tellus. In addition, some data will no longer be provided. Please read the additional information below.

We apologize in advance for any inconvenience this may cause and we appreciate your understanding.

We will continue to increase the data variety provided by the Traveler API and improve the uservility as a satellite data platform.

< Data for which the access method will be changed >

The access method for the following data, which you have been viewing on Tellus OS, will be changed on August 31, 2022. You can use the import function which is already available on Traveler by entering the URL to display the tiled map.

　Standard (GSI map)
　Active Fault Map(GSI map)
　Flood control terrain classification diagram(GSI map)
　Vegetation (GSI map)
　Color-graded altitude map (GSI map)
　Anaglyph (GSI map)
　Magnetic anomaly map(GSI map)
　Lakes data (GSI map)
　Orthoimage(GSI map)
　Lot usage trends survey - Metropolitan areas(GSI map)

The access method for the following data, which was previously available on Tellus OS, will be changed on August 31, 2022. Please view the data on Traveler, which is already open to the public.

　Sea Surface Temperature(GCOM-C)
　Chlorophyll-a(GCOM-C)
