CREATING TH E DIGITAL TERRAIN MO DEL OF THE USAMVB AREA USING MO DERN TECHNOLOGY

The digital model of an object or phenomenon ismade up of asystematically stored data collection (database) that describe s a three- dimensional system of coordinates, arbitrary or particularly can form the object features or states/accomplishments of the phenomenon (conversion as a digital image) and allow by calculation program mes, deducting the object or states shape and features for the phenomenon in new points. Modelling the areas is the process of representing graphically a natural or artificial area by using one or more mathematical equations. Modelling the terrestrial area is a particular case of modelling an area where we shou ld take into account the specific problems of representing the Earth or some of its parts. Severalfieldsin which the digital model hasimmediate applicability are thefollowing: telecommunication systems analysis, pipe networks (water pipes) design, system command and control. The digital system can be appliedinall other fields where it is necessary to know altitude information in different points of an area.The termdigital terrain modelwas used for the first time in 1958 by Miller and Laflamme who defined it asa statistic representation of continuous area by using a great number of points whose horizontal coordinates (x, y) together with the altitude (z) are known and this representation is made in an arbitrary coordinates system �.
