—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 coordinate system.
This paper presents a new system of coordinates by a
harmonic equations “United projections”, who have five
projections (Mercator, Lambert, Russell, Lagrange, and the
compound of the projection) in one zone coordinate system
width 12 degrees, also it has 3 degrees for overlap between
zones, as well as five standards parallels for zone from equator
to 75 North (South).
Also this paper presents two cases; first case is to compare
distances between the new coordinate system and UTM, second
case creating local coordinate system for city of Hong-Kong for
measuring the distances directly from rectangular coordinates
using Mercator, Lambert and UTM projection. All results
compared by geodesy indirect problems.
