Project 1: Coordinates and Projections
Objective:
understand
projections and which geometric properties (i.e., sizes, shapes, distances,
and directions)
are preserved, and which are distorted; understand the geographic coordinate
system
Geographic
Projection: This is a Mercator Projection of the world which includes my home town of Minneapolis, Minnesota. The geographic coordinates of the projection center are 0,0. The Mercator projection has straight meridians and parallels that intersect at right angles. This means its strength is in its use for navigation. The geometric property preserved on a map using the Mercator projection is shape, while sizes of land masses are distorted. |
Geographic
Coordinates: The place name shown on the map above represents the location of my home town. The geographic coordinates of my home town are: Latitude: 44° 58' 48" N, (N44.98 decimal degrees) Longitude: 093° 15' 49" W (W93.26 decimal degrees) |
UTM
Coordinates: The UTM coordinates (NAD83) of my home town are: Easting: 479,216.185 meters, Northing: 498,0762.454 meters, Zone: 15 |
State
Plane Coordinates: The State Plane coordinates (NAD83) of my home town are: Easting: 320265.665 meters, Northing: 858059.123 meters, Zone: MN S (22-03) |
