INTRODUCTION
Another fundamental concept that effects everything we do is that the earth is round ( or close to it ...) and maps are usually flat. This means we have to make a mathematically transformation of every point on the hypothetical earth to the flat map. This is called a map projection. We will cover this and other related topics this week.
LEARNING OBJECTIVES
- Define geodesy
- Define map projection
- Describe some of the early measurements of the earth's shape and size.
- Describe why a map projection is important ot cartography
- List commonly used map projections
- Describe some ways the early the circumference of the earth has been estimated
- Explain what a datum is used for
- Describe geographic coordinates
- List the 3 comon projection surfaces
- Describe the Universal Transverse Mercator
- Describe the State Plane Coordinate system
