SYNOPSIS |l | 
This thesis describes the history of a study of infrared aerial photography, which was || fi 
. : | il 
started in 1956 in Japan and which is still being continued, and the practical aspect of its | il 
application to civil engineering. Ld | 
This study is being conducted principally by the Institute of Industrial Science, University |] | 
of Tokyo and covers a wide range from the basic department of photographing to practical He I 
application. | | 
The results of this study amply confirmed the superiority of infrared photos over for- | | | 
. : . . a . I 1 
merly used panchromatic photos, in aspect of preliminary survey, especially photogeologic | n 
investigation, for planning of various construction project, the details of which will be exem- mI | 
plified in the photos contained in this report. I. di m"
