Calculate Radius of a Spherical Earth that Corresponds - Engineering Assignment Help

Assignment Task :

PART A - LAW

The first block lecture discussed the Geomatics Profession Act (No 19 of 2013) (GPA).  You are tasked with the following:

1. The GPA is a relatively new Act and replaces the old PLATO Act entirely.  

   1. Elaborate in your own words the compilation of the new Geomatics Council on whether they would meet the transformation targets of the geospatial fraternity.  You should list and discuss at least 3 areas the GPA is targeting (or “providing for”).         

   2. Give your general comments or opinion on the Act itself by elaborating on how it will affect you, a geomatics practitioner.  This is an open-ended question therefore a minimum of 200 words is expected. Consider types of companies permitted, who can be directors of such companies, work reservation etc.

PART B – SPHERICAL TRIGNOMETRY

2. On the spherical earth, list and explain which of the following is a great circle, which a small circle and which not a circle at all? parallel, meridian, rhumb line, equator, geodesic, polar axis (don’t only reference my notes here!!!). Tabulate your responses.               

3.  The nautical mile is defined as the length of 1 minute of latitude change along a meridian at the equator. It is also defined as 1852 international metres. Calculate what radius of a spherical Earth that corresponds to (round to a full km)

4.  (a) Draw a labelled sketch of the spherical triangle you could use to measure the distance and starting bearing from Canberra (34.3?S 148.6?E) to Darwin (13.4?S 131.8?E). Your sketch should show the equator, Greenwich meridian and the North Pole. It must also have all known sides and angles correctly labelled with their numerical values.                                                     

 (b) Calculate the shortest distance from Canberra to Darwin in nautical miles and the starting bearing in decimal degrees.                                                                                 

5.  Which civilization is credited with developing the theory of spherical trigonometry? How did its measurement of the size of the earth encourage Columbus to sail West across the Atlantic in the hope of finding India? (don’t only reference my notes here!!!)                                      

 (a) Suppose a flight is planned from Durban (lat. 29°S,31°E) to the Camoros (11°S,43°E). What is the name of the shortest route? Find this starting bearing and shortest route length
