From June 28 to July 2, Fujiwara(D3) and Yoshimoto(Project Academic Specialist) went to Ahira Town in Hokkaido for a field survey. The purpose was to take photos using an UAV to create a 3D model of the forest. We also accompanied the Kuwano Lab in their research. The humidity in Hokkaido was very low and very comfortable. The purpose of the Kuwano Lab was to survey the area where the cave-ins had previously occurred. We helped create an artificial hole about one meter deep. Since I don't usually exercise, it was very hard work for me, and I got muscle aches.

During December 10 to 14 Fujiwara (D2) visited Yangon Technological University in Myanmar. The temperature on day was about 30 ℃ but humidity was less. The purpose of this visiting is collect a point cloud data of the single trees by 3D measurement using a terrestrial LiDAR. He arrived Yangon at 10 and he did that between 11 and 14. On 11, he learned how to use the LiDAR and was looking for target trees. Although the measurement time depends on sampling resolution, it takes about 20 minutes and from 3 direction is needed to get whole tree data at least. Therefore, it took 1 hour to get the data. The temperature on day is about 30 ℃ but humility is less. Finally, he got a 6 tree data. These data will be useful to his research. He also enjoyed Myanmar food with lunch and dinner. Every food was delicious for him and came to like Mohinga and Kyay-Oh.

7-8. Mar, 2019

After the scientific conference on March 6 of the 27th IIS Forum on disaster monitoring and risk assessment from space. Members from the Takeuchi laboratory of ‘Remote sensing of environment and disaster’ held a two-day workshop to introduce Google Earth Engine on March 7 and 8. Twenty five international remote sensing scientists of diverse research interests participated in the workshop. We welcomed a diverse group of participants, who have different specialty in remote sensing, from satellite data provider, ecologist, forestry to computer vision scientist. Two thirds of the participants were female, which was an exciting news for gender equality in scientific participation in Japan. Most participants were new to GEE, and everyone was looking forward to applying GEE in their research.
The workshop was structured in three sessions: Introduction to GEE, Overview of advanced features and in GEE, and a mini-hackathon, conducted by Dr. Prakhar Misra , Ms. Pegah Hashemvand Khiabani, and Mr. Xuan Truong Trinh, respectively.
In the ‘Introduction to GEE’ session, participants were exposed to motivation behind use of cloud based processing and examples were shared. This was followed by exploration of various datasets through EE tags and displaying them in the workspace. Finally the goal collection of training pixels of 4 land-cover classes in Landsat 8 imagery and the scene classification, followed by saving the result to the Google Drive.

The final session of the training workshop was a group project to bring ideas obtained during the training into application. Participants grouped themselves into small groups of 5-6 members to prototype an application for solving a remote sensing problem in an innovative way, utilizing the unique strengths of Google Earth Engine. Ideas were focused around stack-based classification rather than pixel-based classification in order to take into account the temporal patterns of phenomena on the earth surface. The topics pitched by the 4 groups were:
・ Unsupervised land cover classification, especially of crop species, by their phenology, reflected by their NDVI index, for the whole Japan.
・ Species specific classification of forests in North Korea by observing their unique pattern in seasonal variation.
・Detection of beetle-caused disease which induce massive forest loss in Mt. Zaou and disease risk mapping.
・Landslide detection and risk mapping in Hokkaido in response to the Hokkaido earthquake in 2018

The mini-hackathon emphasized on the prototyping of new ideas rather than the coding process. This helped remote sensing scientists appreciate the unique strengths of Google Earth Engine in executing rapid time series analysis and incorporating powerful machine learning-based classification methods.
At the end of the session, many participants expressed their astonishment on the power of Google Earth Engine, its easy of use, and its applicability in their current research.
“Being able to do such a complicated phenology-based classification at such a large scale, in such a short time, was amazing.” - exclaimed a veteran scientist.
“GEE gave me new ideas to work on my current research” - said a graduate student.
“GEE is very useful to promote scientific research in developing countries, because of people can access an enormous computing power for no cost.” - observed an experience user of GEE.

We also received and realized some suggestions for our future sessions -
- More discussions needed towards explanation of the image related functions and also to syntax of the Javascript in general
- Need to discuss indices produced by various band combinations and their limitations. This is especially true for distinguishing between snow & cloud.
- Some participants expressed intention of using both Landsat and Sentinel imagery in the same analysis by some kind of fusion.

On 2019.02.05, Dr. Genki Terauchi and Dr. Eligio de Raus Maure visited the Takeuchi lab to discuss about seagrass mapping situation. Dr. Terauchi and Dr. Maure are from the Special Monitoring & Coastal Environmental Assessment Regional Activity Centre (CEARAC), which is hosted by the Northwest Pacific Region Environmental Cooperation Centre (NPEC) in Toyama, Japan. Two doctor candidates, Han and Truong, represented the lab to present about their research. Seagrass mapping status in Japan, China and Vietnam was discussed. It was understood that though various attempts have been done, current seagrass mapping in these three countries could still be largely improved by further apply remote sensing technology. Specifically, there have been various reports of seagrass distribution in this area, yet the exact extent and density is largely unknown. By gathering high-quality ground truth information, standardizing classification method, and publishing the seagrass distribution mapping results organizedly, understanding of seagrass distribution can be greatly enhanced. It would be a crucial enabler for coastal conservation. We are looking forward to further collaboration for seagrass and blue carbon mapping.

Our Laboratory held small seminar. The topic is classification of objects in old Japanese map. A couple of decades ago, the satellite images were not common, so maps were only way to know what there were in those days. In order to make it clear, we had to read map signs and add color to make it easy to read. We used machine learning and tried to make it automatically. About 4 under graduate students and a few lab members attended it. Before making computer learn data, we had to make train data, which computer learn what each signature means. We made poligons which surrounding the same signs a lot and enjoyed it a lot. The training data showed the personality very well. One categorized small area precisely. Other one made rough poligons in a short time... The outcome was so so. We considered the reasons and discussed with Prof. Takeuchi. I believe it was not my fault. We should also duscuss how to improve the quality from now on. Any way we completed our mission. We also had BBQ party in August 10. All of the lab members, some former members and some undergraduate students who took the course in this lab joined. We enjoyed eating meat, drinking sake and talking a lot.

On April 5, 2018, Takeuchi lab went to Komaba Park for a picnic. Although no more cherry blossoms could be seen, the trees and grasses welcomed the group with cool air that made it a perfect day for lunch together in the park. Right after the picnic, the group also went to the old Maeda Family’s house located within the park itself. This was not part of the plan that day, but it’s as if the house is attracting the group to come inside. We were privileged to explore not only the rooms allowed for visitors but also to some rooms which were restricted from ordinary visitors. The house was unique because tatami floors can be seen everywhere in the house, not only inside the rooms. The garden was also fascinating. You can imagine sitting in the veranda and sipping a cup of coffee or tea while enjoying the relaxing feel of the garden in Maeda family’s house. It’s interesting to know that in the busyness of research work, we can go outside and in around 10 mins by foot, we can be refreshed in a nearby park and a well-maintained family house and garden.

The Autumn has come. Our campus becomes the most beautiful in this season, this colorful season. I feel autumn every year, when I see this yellow covered campus and get a sniff of ginkgo. When I was freshman, I hated the smell and was depressed to come to the campus in this odor season. But I adapted to this stink before I knew it, and now without it I cannot even recognize the change of season in Tokyo, the city whose land is almost covered with asphalt and with few trees. Maybe our lab members also feel the same. It is getting colder day by day. Some of our lab members seem to feel sick now, so please take good care of yourself. Dress heavily, drink hot, and prepare for severe coldness. Winter is just around the corner

Sep 3th to Sep 9th, Seina's visit to Vladivostok, joining student forum. I have visited Vladivostok from 3rd Sep to 9th Sep to join a student symposium. Prime Minister Abe and President Putin had a Japan-Russia Summit Meeting last year (2016 May), and they agreed on improving 8 areas to benefit both countries. One of the 8 agreement, it says, "Fundamentally expansion of people- to people interaction". This student symposium was held for the first time to realize the 8th topic by encouraging university students to interact with each other. 26 students from Japan and Russia have joined the forum and discussed about Japan-Russia relationship and how we can improve our relation in the future. In addition to the discussion, we had cultural activity including visiting summer camp site and historical museum of war etc. We also had a chance to audience Prime Minister Abe and President Putin during the forum, and also had a small chat with well- known Judo player Yasuhiro Yamashita. This experience was such an insightful event for me that it definitely changed my life to some extent for sure. Witnessing the scene of politics move and being fitted in for a project which was directly decided by leaders made me to feel more engaged in about the movements of the society, of the world, and I realized I have to be more aware of me being a responsible person who might be able to change the world. I've been always wanted to change the world a better place to live in and make Japan a better country, but it was always a big dream without any realistic feeling of achieving it. But now I am aware that I need to think of it as my realistic dream, otherwise, it will end up just being a dream. I know I cannot do anything big enough to change the world today or tomorrow, but having this perspective of making Japan a better country always in mind will surely help me to head towards the dream in the long run. I really appreciate all the support of Takeuchi sensei even though it was just before the submission of ACRS, and all the support of core universities' professors and government side support and lab members and family member's support for letting me have this incredible experience.

Kazuki Inoue’s visit to Yangon, Myanmar. I studied in Myanmar for 15 days from August 19th to September 2nd with an overseas study abroad scholarship which UTokyo provides and aims to encourage students to deepen their international understanding and to contribute to nurturing human resources who act on the world stage. I am currently studying the railway condition monitoring using the portable device for Myanma Railways (MR). When conducting the first field survey in February 2017, we measured the acceleration of the car body using a smart phone based accelerometer for the Yangon Circular Railway Line (YCR). This time is second visit to Yangon for me. During the first half of the week, I stayed in Yangon city, joined a discussion with students at Yangon Technological University (YTU) and conducted a field survey of the YCR Train. In the latter half of the week, we took an express train to Mandalay station approximately 550 km from Yangon station to measure the train acceleration for the intercity railway. Also, fortunately, I got the opportunity to talk with the professor at Mandalay Technological University. I got an explanation from an expert about the difference of traffic situation among cities in Myanmar and the current situation of MR. YCR timetable in Burmese. I don’t understand but MR staff kindly explained me. The YCR is currently being implemented with technical assistance by the JICA expert team and an improvement plan with ODA loan. Currently operated at a speed of about 20 km / h, the MR improves it to about 40 km / h, and increases the operation interval at commuting rush hour from about 2 per hour to about 5. At that time, more advanced and precise maintenance is required, but at present there are 600 derailment accidents per year on all railway lines operated by MR. Based on these backgrounds, we conduct field surveys as research subjects to conduct efficient railway condition monitoring using simple measuring equipment and satellite images, and conduct analysis. While staying in Yangon, I stayed at YTU 's guest house. In Yangon, blackouts occurred frequently. There was a power outage of several hours once every two days. In the night darkness, I stayed in the room while relying on the lights of the smart phone. As I was born and raised in Japan, I have never experienced a blackout, so these new experiences broke my conventional sense and trained me. I learned that "I should do while I can." I am sincerely thankful to YTU members who helped me during my stay and my university and laboratory who gave me valuable opportunities.

Visiting the exhibition of machine vision in Yokohama during 7-9 December 2016.

The exhibition of machine vision was held at Pacifico in Yokohama (Japan's second largest city) during 7-9 December 2016. This event aims to display the current technology of machine vision including cameras, mechanical devices and digital image processing with the various applications for industrial fields. Many industrial staffs, researchers, professors, students and those who are interesting in camera technology were gathered in this exhibition for showing their works and seeing the other works. For the highlights of this exhibition, a very tiny camera can record in video mode with a high resolution of 4K pixels. A sensor can capture an image of very fast moving items. The real-time image processing technology demonstrates the several potentials in many applications such as the simulations of controlling cars in roads and trains in railways without manual handles.
