Divide the area of Egypt into 3 vertical strips (zones) extending west to east. Three Zones are named: Purple belt (Western Desert), Red Belt (Nile Valley), and Blue belt (Eastern desert). Zone Width: 4° degrees of longitude, two degrees at each side of the central meridian. Central Meridian: mid-longitude of each zone.

2016年11月3日 · In Egypt Universal Transverse Mercator (UTM) and Egyptian Transverse Mercator (ETM) are used for production of maps. To transfer data from one to the other system, the projection scale factors are different for the two systems and ignoring it in these transformations can led to large errors.

Area of use: Egypt - onshore between 29°E and 33°E, offshore Mediterranean east of 29°E and offshore Gulf of Suez. Coordinate system: Cartesian 2D CS. Axes: easting, northing (E,N). Orientations: east, north. UoM: m.

The ESA decided to replace the EGD30 and the associated projection system, Egyptian Transverse Mercator (ETM), with the WGS84 and the associated projection system, Universal Transverse Mercator...

The ETM projection system divides Egypt to three main zones (belts) purple belt, red belt and Green belt. Each zone has a longitude width of 4° and has its origin of coordinate system as shown in figure (1).

In this paper we will study the effect of distortion caused by Scale Factor and trying to get the Scale Factor relationship between ETM and UTM systems in Egypt. Figure 1: Zones of ETM Projection System in Egypt [10]. zone has a longitude width of 4° and has its origin of coordinate system as shown in figure (1).

Simplified view of contiguous US UTM zones, projected with Lambert conformal conic. The UTM system divides the Earth into 60 zones, each 6° of longitude in width. Zone 1 covers longitude 180° to 174° W; zone numbering increases eastward to zone 60, …
