POPULATION ESTIMATION USING GEO-INFORMATICS WITH DIGITAL INSTRUMENT

Abstract

ABSTRACT. Geo-informatics can be very useful for estimating population in fast growing newly build-up area of any third world cities. Reliable result can be achieved with the aid of an interface digital instrument to a photogrammetric stereoplotter. This enables digitization of all buildings or erected structures of habitable nature. Samples are then taken and from data acquired from a previous census, estimates can be derived. This method has proved to be faster than the conventional head-to-head count; it is cost effective, since manpower requirement is less. The use of digital instrument and appropriate computer softwares and techniques adds the convenience of this method.
