Fall 2014

2 Location, Distance and Area on Earth
Conversion of degrees, minutes and seconds to decimal degrees Computation of distance along parallels and meridians Computation of area Question 1 of Midterm 2013 Question 3 of Homework 1, 2014

3 Map Projections Types of map projections (Conic, Cylindrical, Azimuthal) Projection parameters and how they lay out on a map Origin in geographic and projected coordinate systems Location in a coordinate system Question 1 of Homework 3, Question 1 of Midterm 2013
