No. 1: Support for JupyterLab and the R programming language (other features have been expanded as well)

Good news for those who use the development environment (Jupyter Notebook). Tellus now supports JupyterLab!

The R programming language as well as Python 3 are now fully supported by Tellus. In addition, the features of Tellus OS have been enhanced. See “Other updated features” for more information.

If you have already assigned a Jupyter Notebook development environment, it doesn’t automatically switch to JupyterLab. Another application is required.

No. 2: ASNARO-2 data

SAR images created by ASNARO-2 have been added (200 scenes around Tokyo, Osaka and Nagoya).

SAR images can now show landscapes of cloudy regions. See this article for more information about the SAR images.

Tellus is the only platform where you can view and analyze ASNARO-2 images as of June 2019. Enjoy ASNARO-2 images on Tellus!

No. 3: Location information data

The location information data service “Profile Passport” is now available.

Human density of each mesh is visualized in the form of a heat map, although presently only data for Tokyo and its vicinity between July 2016 and September 2017 is available.

We will publish data for every region of Japan one by one.
