New release

Automatic extraction of changes in cities and buildings from two satellite images! New Tellus tool “Tellus-DEUCE” is now available.

We will introduce what you can do with the new Tellus tool "Tellus-DEUCE," released on the 25th of February 2021, which can automatically extract the difference between two selected satellite images using AI, showing some actual screenshots and how to use it.

The 4th Tellus Satellite Challenge! Explanation of approaches taken by the winners

"Coastline extraction" was the theme of the 4th Tellus Satellite Challenge. In this article, we will look at the approaches taken by the winners, make comparisons, and summarize their methods so that they can be applied to other (satellite) image data competitions.

Is the Susanoo Shrine built in a location that is resistant to flood damage? We took a look at the enshrined deity and used satellite data to examine the city it is in.

In this article, we will be using the satellite data platform "Tellus" to look into a series of shrines called the Yasaka Shrines, which have both Buddhist and Shinto aspects to them. We will look specifically at their Hikawa sect which enshrines the deity Susanoo. Looking at Shrines From Space! Pretty Cool, Eh?

Time has come for 37 space companies to say goodbye to 2020 and welcome in the New Year, 2021!

In this article, we ask each of the 37 Japanese space companies about their highlights in 2020 and their resolutions for 2021. What kind of year was 2020 for the Japanese space industry?

Space business

The Shift to a Five Axelspace GRUS Satellite System. The roadmap to achieving profits of $100 million.

Axelspace released their plans to launch four GRUS small satellites. The company shared its revenue goals at the unveiling of its satellites. Along with a summary of the event, we here at the SORABATAKE editorial department would like to share an estimation of how many satellite images they will need to sell to achieve their goals.

How to use

Using Amedas Data to Visualize Temperature Forecasts and Rainfall in Real Time.

For this article, we used the Amedas minute-by-minute data available on Tellus for our analysis. We looked specifically at the minute-by-minute Amedas data in northern Kyushu for rainfall that occurred between 5th and 6th of July 2017.
