Environmental monitoring in East Asia

EMEA（东亚环境监测）项目旨在促进植被研究方面的合作，特别侧重于遥感及其地面实况，由中国、韩国和日本的贡献组成。它始于2002年，我们进行了实地工作，会议和研讨会。1.利用卫星数据分析植被环境现象往往表现出不同的特点，这取决于观测的规模。为了检测环境变化，确定空间和时间分辨率是重要的。为了监测植被特征，利用NOAA、Landsat、IKONOS等多种卫星遥感资料进行了研究，利用NOAA数据分析了植被的时间变化，利用Landsat数据分析了植被的时空变化。为了利用IKONOS卫星1 m空间分辨率的数据进行单木检测和树种分类，采用了一些图像处理技术。2.中国和韩国的实地研究我们于2002年8月访问了韩国北方地区，2002年9月访问了中国北方地区，2004年9月和2005年8月在中国东北地区举办了国际会议和研讨会。（东亚生态学会联合会）国际大会，2004年10月20日至24日，韩国木浦。利用遥感监测植被变化（2）IEEE国际地球科学和遥感专题讨论会，韩国首尔，2005年7月25日至29日，会议名称：利用卫星图像分析东亚植被。（3）EMEA（东亚环境监测）国际专题讨论会，金泽，日本，2005年11月28日至29日。

The EMEA (Environmental Monitoring in East Asia) project has been designed to promote cooperation in vegetation research with a particular focus on the remote sensing and its ground truth, and consisted of contributions from China, Korea and Japan. It started in 2002, and we had field works, meetings and symposium.1.Analysis of vegetation using satellite dataEnvironmental phenomena often exhibit different characteristics depending on the scale of the observations. To detect environmental changes, determination of spatial and temporal resolution is important. To monitor vegetation characteristics, we conducted research by using of a several kinds satellite remote sensing such as NOAA, Landsat or IKONOS.Temporal change of vegetation was analyzed using NOAA data and spatio-temporal change of vegetation was analyzed using Landsat data. In order to detect individual trees and classify tree species using IKONOS data with 1 m spatial resolution, some image processing techniques were adapted.2.Field research in China and KoreaWe visited northern parts of South Korea in August 2002, northern China in September 2002, and northeastern China in September 2004 and August 2005.3.Organization of international conferences and symposium(1)EAFES (East Asian Federation of Ecological Societies) International Congress, Mokpo, Korea, 20-24 October 2004.Session title : Utilization of remote sensing for monitoring of vegetation change(2)IEEE International Geoscience and Remote Sensing Symposium, Seoul, Korea, 25-29 July 2005.Session title : Utilization of satellite imagery for analysis of vegetation in East Asia.(3)EMEA (Environmental Monitoring in East Asia) International Symposium, Kanazawa, Japan, 28-29 November 2005.Theme : Remote sensing and forests
