Abstract
It is well known that Landsat MSS CCT data are very useful for reserch of enviromental problems. However, remote sensing system requires large computer and expensive peripheral equipments for processing large amounts of data, so it is impossible to get the system in each individual laboratory of university.
Therefore, it is necessary for us to develope low cost remote sensing system, in order to study of waters effluented from Ishikari river by Landsat MSS CCT data analysis. The developement of a new system is a difficult work but we must do it.
This report describes the low cost remote sensing system, displayed images of Landsat MSS and hydraulics model test.
This system is connected with telephone line between Melcom Cosmo 700-III and personal computer, in which a mini-floppy disk is used as a data storage divice. Melcom Cosmo 700-III (Host computer) belongs to computer center, Faculty of Engineering, Toyo University.
Personal computer (Sharp X1/RAM memory 64K bytes) is used as intelligent terminal. Minifloppy disk (two drives), RGB monitor ( 200 rows of 640 columns in 8 colors) and dot printer are used as peripheral equipments.
Total cost of this system is \450, 000
The speed of the data transfer through the telephone line is 300 bps and the mini-floppy disk has a storage capacity of 256 pixel times 200 line times 4 bands data by 8bits.
Then we have done the simple model test, which main purpose is to study the flow pattern from river and temperature distribution. The experimental results have given us some suggestions for Landsat MSS CCT data analysis.
The image of iso-concentration contours has a good agreement with the experimental results.
The obtained images are very useful to study on dispersion of waters effluented from river.
