Satellite Remote sensing, the technique of gathering information about objects located on the earth's surface can also be used as methodological procedure for the archaeological investigation and interpretation on important issues like the identification of palaeochannels , older fluvial plains and deltic distributors etc.
The study area comprises the western part of Karbi Anglong district of Assam which is located in the north eastern part of India. The area is located between 25* to 26*40'N latitude and 92*50' longitude. The survey area is covered by the 83B/8, Survey of India toposheets(P-15, R-49). The geomorphological features include structured hills, undulating plains, valleys and fluvial land forms. Some parts of the satellite image is also covered by jhum fields i.e. slash and burn cultivation and deep forests.
The present investigation is an endeavour to understand the major geomorphological features of the area having archaeological interests form the geo coded satellite images. The satellite images are acquired by the Indian Remote sensing satellite IA ,L2A of path and row E15 R49 having bend resolution 234 acquired on 7th of March'1991.
The interpretation of the image is done by visual analysis of colour, texture and pattern . The presence of palaeochannels in the same parallel directions in the satellite image of the studied area suggests that the river shifted to the new directions from its original position. Therefore from the satellite image it is well established that in the western part of the Karbi Anglong district, two fluvial plains existed , one is the older and the other is the present.
The older fluvial plain yielded neolithic sites along with the megalithic monuments. The extant of palaeochannels supply with data for the possible dimension of early human habitation grounds.
