The Ideal Map Projection for Sea Ports

Akresh Mohammed Sabri and Ali Said
Abstract—The modern technologies and developments in computers and Global Positioning System (GPS) as well as Geographic Information System (GIS), become very important in present time in mapping and sea navigation. Traditional map projection systems are not suitable for modern technologies, because they haven`t high accuracy in determining the position of features, also when calculating the distances compared by Indirect Problems of Geodesy (I.P.G) it have bad results. This paper presents new method for map projection use in sea navigation specially in sea narrow paths were the risk of ship crash become very high. The map projection by harmonic equations method was used. The results show that the error in short distances was between 0.0 and 30.0 cm compared with 20.0 cm and 450.0 cm error when UTM system was used. Local system method by harmonic equations shows better results than other methods.

Index Terms—Map projection, GPS, GIS, Harmonic equations, UTM, Geodesy.
