The Ministry of Economy, Trade and Industry (METI) has been promoting utilization of the satellite data platform called “Tellus.” As part of this effort, METI decided to hold the third data analysis contest titled “Tellus Satellite Challenge” and will start a call for entries into the contest on October 4, 2019. METI is looking forward to receiving your application.
From the viewpoint of promoting establishment of new business making use of satellite data, METI has been conducting the Project for Establishment of Open and Free Government Satellite Data and Business Environmental Arrangement for Data Utilization from FY2018. Since then, it has been advancing development of a user-friendly satellite data platform called “Tellus” and released a prototype version of the platform in February 2019. METI considers it important to promote utilization of satellite data and also to uncover and foster potential human resources that are able to analyze and utilize satellite data, and from this viewpoint and as part of the project, it decided to hold the third satellite data contest titled “Tellus Satellite Challenge.”
In the third contest, METI will request entries to take on “detection of sea ice regions by taking advantage of data from a synthetic aperture radar (SAR)” as the subject of the contest.
Currently, the First Regional Coast Guard Headquarters has been providing the public with information on sea ice for the purpose of preventing ships from being involved in maritime accidents caused by sea ice floating in the areas surrounding Hokkaido Island. The headquarters has been engaging in not only observation of sea ice using aircraft and patrol vessels but also analysis of observation images of sea ices shot by a satellite. The data sent from the satellite is useful in ascertaining the conditions of wide sea surfaces at a glance, but currently, analysts are required to have high skill to identify sea ice regions from the data obtained by SAR, a technology capable of shooting images regardless of daytime, nighttime or weather conditions.
To overcome this challenge, this contest aims to develop algorithms for detecting sea ice regions from SAR data in a highly accurate manner. The data that entries are required to use is observation data obtained by PALSAR-2,* a sensor installed in “DAICHI-2” (ALOS-2), an advanced land observing satellite-2 flying over the sea areas surrounding Hokkaido Island.
Outstanding entries that have successfully developed algorithms with high detection accuracy will be honored and the algorithms will be disclosed to the public in a form adopted to Tellus for use. METI is looking forward to receiving your application.
2. Outline of the contest
Detection of sea ice regions by taking advantage of data from SAR
The data that entries are required to use:
Observation data obtained by PALSAR-2, a sensor installed in “DAICHI-2” (ALOS-2), an advanced land observing satellite-2 (copyright holder: Japan Aerospace Exploration Agency (JAXA))
*Note: PALSAR-2 is a sensor, commonly called “SAR,” that irradiates ground surfaces with electric waves and receives the waves reflected from the surfaces so as to obtain data on the surfaces. SAR is characterized by permitting observers to observe ground surfaces regardless of daytime, nighttime or weather conditions.
Period of the contest:
From October 4 (Fri.) to November 30 (Sat.), 2019
Note:The last day is tentative
Prizes for winners:
First place: 1 million yen
Second place: 600,000 yen
Third place: 400,000 yen
Note: These prizes will be provided by SAKURA Internet Inc.
Release of the examination results:
The results of the contest will be released around late January 2020.
