Remote Sensing Laboratory, Field Science Center, Graduate School of Agriculture Science, Tohoku University starts at April 2004. For studies and education at the laboratory we are now developing the system of remote sensing and GIS. Earth Remote Sensing Data Analysis Center (ERSDAC) made the Home Pages of Terra/ASTER Image Web Library 3 "The Major...

To use remote sensing techniques for agricultural monitoring, near-real time data acquisition, treatment, and distribution are necessary. For this reason, we are now developing Satellite Image Data Base System (SIDaB). First, we will introduce our SIDaB system, and our future plane of satellites data acquisition. Using network systems such as Asia...

The objective of this study is to promote agricultural remote sensing using satellite data, and we want to develop the method of hyper spectral data for encouragement to next generation satellite in Japan. We find a suitable vegetation index to evaluate biomass of vegetation. The first-order derivatives were calculated based on the field measured r...

In order to grasp the amount of water resources for agricultural production in Asian region, the map of cropping pattern is necessary. In this study, we tried to create the cropping pattern map of East China using time-series NOAA-AVHRR NDVI 10-days composite data (1997-1999). The LMF method was used as the periodic function in this study, and in c...

Satellite remote sensing provides wide-ranging and temporal information on grasslands, which are indispensable for proper grassland management. In this study the satellite monitoring of annual changes of grasslands is discussed. By applying a new method which utilizes a Grassage Standard Map to a study area in Konsen Plain, Hokkaido, Japan, increas...

Once grassland productivity decreases, grass-renovation, accompanied by plowing and seeding, needs to be conducted to improve its productivity. Years after grass-renovation is one index indicating grassland productivity. In this study, the monitoring of grass-renovation status using satellite data is discussed. By extracting 1-year grassland and re...

After being dormant for a long time, Mt. Pinatubo volcano located on Luzon island in the Philippines erupted violently on June 15, 1991 (Evangelista 1993). During successive rainy seasons, 1991 to 1993, large mudflows spread on the surrounding areas. The detailed chemical, physical, and mineralogical characteristics of these mudflow materials will...

To use of remote sensing techniques for Agricultural monitoring, it needs semi-real time data acquisition, treatment, and distribution. For this reason we are now developing Satellite Image Data Base System (SIDaB). First, I introduce our SIDaB system, and our future plane of satellites data acquisition. Using network system such as Asia Pacific Ad...

A study was conducted to assess the applicability of using small, passive corner reflectors for geometric correction of RADARSAT Fine Mode SAR data. Five 1-m width trihedral corner reflectors were constructed, using aluminum plates, and deployed. The geographic locations of the reflectors were measured using differential GPS. The performance of the...

A study was conducted to investigate the backscattering characteristics of paddy fields and the potential of C -band/HH RADARSAT Fine Beam mode SAR data for rice growth monitoring. Measurements of field parameters were made concurrent to image acquisition. The SAR data was fully calibrated by correcting the LUT scaling gain and incidence angle vari...

Leaf Water Content Index (LWCI) was proposed by Hunt, E. R. Jr., and et al (1987). At the beginning we tried and succeeded to develop this index for the practical application to the satellite remote sensing data such as Landsat TM. Next we performed vegetation monitoring using LWCI by SPOT Vegetation and we got same results. LWCI is not susceptible...
