GEOG 160 Project 1:
Coordinates and Projections
Sean Swanepoel
Mercator Projection
The shape and angles of continents and landmass ate preserved, however; the further
you move from the equator the greater the distortion is in area or land size.
Polyconic projection
Scale is true along Parallels, such as a longitudinal line. No properties are preserved and the further the point
away from the longitudinal line the greater the distortion in size and shape
Equal Area Projection
Area or size of continent is accurate and maintained but the shape and angles are distorted
Geographic coordinates:
Latitude: 29° 51' 0 S, Longitude: 31° 1' 60 E
A coordinate system which uses 3-D spherical area to locate a point on the earth, it is based on the spherical shape of the earth and a degree system which totals
360 Degrees. Using Longitude and Latitude and location on earth can be referenced by a degree system.
UTM Coordinates:
Easting: 692389 meters, Northing: 6474388 meters, Zone 35J
UTM or Universal Transverse Mercator divides the earth into 60 zones each 6 degrees of longitude wide and these zones extend from a latitude of 80° S to 84° N.
The first zone starts on 180 degrees longitude which is the international date line. UTM coordinates are represented in meters to the east (Easting) and to the north
(Nothing).
State Plane Coordinates:
*No State Plane Coordinates for my area
There are 12o State Plane Zones and each state has its own zone. The number of zones in a State is determined the size of that state. This form of referencing is good because it divides up political boundaries and counties.
