Abstract
Land improvement project is supported technically by "Nogyo-doboku". Nogyo-doboku is the name of irrigation, drainage and reclamation engineering which has made progress in Japan as a system of technology for agricultural infrastructure development. In these days, a subject of Nogyo-doboku spread in the field of life environment and even in that of natural environment. Nogyo-doboku is developing into new technology for creation of beautiful country and rural districts where people can live in abundance.
Therefore. remote sensing will be useful in the field of Nogyo-doboku, and it will be available at the time of operating of land improvement project. Especially, it will be of use to investigation for planning of project or monitoring for management of rural district after land improvement project.
We wish and expect the advancement of remote sensing and image processing technique to extract various information on the earth. In this report, we made mention of the application of satellite remote sensing data for investigation of crop damage. The distribution map of rice damage due to cold weather in Ishikari plain was made by using Landsat MSS data. And the map of beet damage due to dryweather in Shari-Abashiri district was made, too. Information extracted from maps like these wil be useful not only for agricultural management but also for planning of land improvement. Next, the accuracy of land use classification in paddy field area was mentioned. As a result of analysis, it became clear that almost all error in classification occured at boundary of land use. Furthermore, monitoring of natural environment around Kushiro-shitzugen using remote sensing was mentioned. This area is peat land area and a view is on a grand scale. We can see many valuable aninals and plants in this area. The changed place of land use or natural vegetation cover during the past seven years was discriminated by overlapping analysis of Landsat data and MOS-1 data which covered Kushiro-shitzugen.
