## What is Adindan datum?

Adindan is a geodetic datum determined in 1958 and suitable for the use in Sudan, South Sudan, Ethiopia and Eritrea. The reference ellipsoid of Adindan is Clark 1880, and its origin is 22° 10′ 7.1098″ latitude, 31° 29′ 21.6079″ longitude.

## Where is Ethiopia in the UTM zone?

WGS 84 / UTM zone 37N.

**What datum does Ethiopia used for projected coordinate system?**

WGS 84 /

WGS 84 / UTM zone 37N Area of use: Between 36°E and 42°E, northern hemisphere between equator and 84°N, onshore and offshore.

**Is UTM 10N a projected coordinate system?**

If someone tells you that a dataset is UTM zone 10N (which is part of a projected coordinate system), the geographic coordinate system information is missing.

### What is datum in GIS PDF?

In surveying and geodesy, a datum is a set of reference points on the earth’s surface against which position measurements are made, and (often) an associated model of the shape of the earth (reference ellipsoid) to define a geographic coordinate system.

### What is geographic grid reference of Ethiopia?

Ethiopia’s latitude and longitude is 8° 00 N and 38° 00 E .

**Does GPS work in Ethiopia?**

There are 24 GPS satellites that go around the earth, and our GPS devices communicate with these satellites for finding location. Since it is designed to work everywhere, GPS is very accurate in Ethiopia, and can identify any location.

**Where is the origin of UTM?**

The natural origin of a UTM zone is the intersection of its central meridian with the equator, but this origin would assign negative coordinates to some locations.

## What is difference between WGS84 and UTM?

The difference is that WGS 84 is a geographic coordinate system, and UTM is a projected coordinate system. Geographic coordinate systems are based on a spheroid and utilize angular units (degrees).

## What is datum coordinate system?

A datum is one parameter in a geographic coordinate system (GCS). The datum is the part of the GCS that determines which model (spheroid) is used to represent the earth’s surface and where it is positioned relative to the surface.

**What parallel is Ethiopia?**

**How do I convert WGS 84 to UTM?**

How to transform WGS84 to UTM using Transformation

- Select input / output spatial references.
- Input coordinates using decimal format.
- Click on the ‘Transform’ button to get the result.
- Your coordinates will be converted using the output spatial reference.

### What is the coordinate system of Sudan?

Sudan – east of 36°E. Coordinate system: Cartesian 2D CS. Axes: easting, northing (E,N). Orientations: east, north.

### How has the South African coordinate system changed over time?

The upgrading, recomputation and repositioning of the South African coordinate system was driven by the advancement of modern positioning technologies and the globalization of these techniques for navigation and surveying.

**Where did the co-ordinate reference system come from?**

Prior to 1st January 1999, the co-ordinate reference system, used in South Africa as the foundation for all surveying, engineering and georeferenced projects and programmes, was the Cape Datum . This Datum was referenced to the Modified Clarke 1880 ellipsoid and had its origin point at Buffelsfontein, near Port Elizabeth.
