Survey of hidden calcrete in alluvial plains of India by airphoto interpretation
The present paper deals with the technique developed in India on the location of hidden deposits of calcrete by the application of airphoto interpretation. Calcrete is a calcareous granular material and is locally termed as kankar. Since large scale road construction programmes are visualized in the country, emphasis is laid on the judicious use of locally available materials so as to reduce the cost of construction. In connection with development of a fast survey technique of such deposits, ground survey and study of aerial mosaics of about 4500 sq. Miles area in the alluvial plains of India have been conducted. It will be shown that a well defined pattern has been recognized on the aerial photographs. Twenty five sites have been selected for field checking and 80 per cent of the sites confirm the airphoto interpretation (A).
