Professor  IWASHITA Keishi

■ Other affiliation / position (Number of the published data : 1) College of Industrial Technology  UCLA Graduate school " Environmental & earth Science"    ■ Profile Keishi Iwashita received a BA in civil engineering from the Nihon University College of Science and Technology, an M.Eng from School of Industrial Technology, and double PhDs from the New York University, Academy of Science in 1998 and the Nihon University in 2009, respectively. He has been on the NUCIT(Nihon University, College of Industrial Technology) faculty since 1983 and was one of the founding scientists of NU Remote Sensing. He has led interdisciplinary studies in two areas: one addresses civil engineering field; the other is in the integration of environmental science using remote sensing with computer science and technology. He is a certified fellowship and a temporary faculty of the University of California, Los Angeles, Image mapping Lab. since 2001, and an international cooperative　member of USEPA Star Grant Research Program. In remote sensing field, he specializes in optics, radiative transfer, and remote sensing in order to ascertain various ocean properties: pigments, detritus, dissolved organic matter, shallow bathymetry, and sea grass coverage.    ■ Current state of research and teaching activities Keishi Iwashita is a Professor in Civil Engineering & Sustainable engineering. He holds two appointments in the Nihon University and in the University of California, LA, SB & Irvine. His research and teaching interests focus on the remote sensing for monitoring pollutants in the ocean environment, to understand the processes through which contaminants may accumulate or transform in water, as well as in the biota, with an emphasis on developing better management strategies for dealing with pollutants in the environment. Current research topics involve the development of new combined radiometric algorithm to correct several unwanted noise of satellite data. Iwashita has had several years experience in instructing "Human Health and Environmental Science" in the School of Medicine at UC. Iwashita received his B.A. in 1978, MSc. in 1981 and doctoral degree in Engineering from the Nihon University in 2009. Also, he received his Ph.D from the New York University in 1998. He has been a faculty member at Nihon University since 1983. He is a recipient of the Best Presentation Awards from the JSCE & the best thesis award from the RSSJ, and the Contribution Award from the UC in 2000 & 2001.    ■ Research Areas (Number of the published data : 6) Environmental Influence Valuation/Environment Policy  Surveying  Civil Engineering Environmental System  Remote Sensing  Computer Science  Other    ■ Research keywords (Number of the published data : 12) Remote Sensing  Computer Science  Surveying  Spectral Reflectance Characteristics  Filament Shaped Method  Trophic State Index  クロロフィル－a  Filament shape  Gordon Method  Band ratioing  DO  filament-shaped method    ■ Subject of research (Number of the published data : 6) Assessment of Oil Polluted Ocean Using Satellite Data  1997-2000  Combined Radiometric Correction for Landsat TM Original Set.  1998-Present  Water Quality Environments by TSI  2002-Present  Terra/Aqua Analysis for Assessing Chlorophyll-a of Water Body  2005-2100  マルチスペクトル衛星データによる貧酸素水塊抽出のリモートセンシング  2010-2013    View details...   ■ Proposed theme of joint or funded research (Number of the published data : 1) Satellite Analysis for Water Analysis  View details...   ■ Bibliography (Number of the published data : 2) 近代測量の理論と実践 ver2  コロナ社  2020/03/01  近代測量の理論と実践  コロナ社  2018/10/05  View details...   ■ Papers (Number of the published data : 55) Analysis of the trend of the deformation around Kanto region estimated by time series of PALSAR-2 data  Geoinformation for Disaster Management  2019/09/01  MODISデータによる諏訪湖の解氷時期の推定　-2つの手法による比較・検討-  日本赤外線学会誌  2019/08/01  The relationships between errors of DEM and the height of ambiguity of Sentinel-1  IGARSS2019 International Geoscience and Remote Sensing Symposium  2019/07/01  Satellite Water Quality Assessment and Monitoring in New Orleans and vicinity  ROE for 2018 EPA Star Grant Research Fund  2019/06/30  Satellite Analysis 2018 Long Island Sound & New York Harbor  ROE for 2018 EPA Star Grant Research Fund  2018/11/26  View details...   ■ Research presentations (Number of the published data : 119) Oral presentation(invited, special)  UAVを利用した都市公園内における樹木の健全度評価に関する研究  土木学会第47回関東支部技術研究発表会  2020/03/01  Poster presentation  諏訪湖の解氷日推定を念頭においたSGLIの正規化海水射出放射輝度プロダクトの評価  日本大学生産工学部第52回学術講演会  2019/12/07  Oral presentation(invited, special)  UAV-LiDARを用いた台風による樹木被害状況の把握に関する研究  日本大学生産工学部第52回学術講演会  2019/12/07  Oral presentation(invited, special)  Sentinel-2可視画像にみられる河川流出パターンの流動の推定  日本大学生産工学部第52回学術講演会  2019/12/07  Oral presentation(general)  静止気象衛星による都市の熱環境に関する研究  日本大学生産工学部第52回学術講演会  2019/12/07  View details...   ■ Prizes (Number of the published data : 4) COSPAR, Presentation Award (Runner-up)  2002/10  Overseas  ERIM, Presentation Award(Runner-up)  1998  Overseas  優秀論文発表賞(日本リモートセンシング学会)  1998  Domestic  優秀講演者(土木学会)  1996  Domestic  View details...   ■ Other research achievements (Number of the published data : 36) Landsat TTM Analysis for Estimating Ch-a Concentration  2000-Present  Experimental Study upon Satellite Remote Sensing for Runoff Analysis  2000-Present  Remote Sensing Analysis for Water Environment-Ch-a Tokyo Bay 2000-  2000-Present  Landsat TTMデータによるフロロフィル-aの濃度推定評価  2000-Present  森林の生育状態を考慮した降雨流出解析  2000-Present  View details...   ■ Memberships of academic societies (Number of the published data : 7) 日本海岸林学会  American Geographical Union  米国写真測量学会  米国リモートセンシング学会 環境モニタリング部会  計測自動制御学会  View details...   ■ Committee Career (Number of the published data : 1) American Geographical Union  Member of AGU Ocean Science Division Conerence Committee  2003/12/01-Present  View details...
