1. Himawari-8 Clipping

Himawari-8 hybrid color images can be clipped for any parts of images, and can be shared in the gallery with a title. A rectangle on the left side of the image should be clicked to draw the clipping area by the rectangle. The scroll bar on the image can change the time for a few days before and after the day. When you would like to change the date more, you can use the calendar appearing in the right-most box.

The clipped images can be exhibited at Himawari-8 Gallery or be shared on social networking services (SNS). For example, you can see Digital Typhoon at Pinterest.

2. Technical Information

This service is based on IIIF (International Image Interoperability Framework) compatible open source server and viewers. IIIF is a framework mainly developed by libraries and museums for browsing digitized cultural heritage images, but the framework can be applied to any types of high resolution images. In the case of Himawari-8, an image is as large as 11,000 pixels by 11,000 pixels, and the archive already stores more than 50,000 images in one year's operation.

To browse such a large spatio-temporal image archive smoothly in a multi-resolution manner, we use IIIF Curation Viewer timeline extension, developed by Center for Open Science in the Humanities, Joint Support-Center for Data Science Research, Research Organization of Information and Systems.
