Module 6 - Scale, Reference, and Coordinate Systems

The test will cover Geodesy, Map Projections, and Scale, Reference and Coordinate systems. Defining Projections and Projecting data in ArcMap

INTRODUCTION

This week we finish off the 3rd topic of the semester involving earth-map relations. We started with Geodesy, then moved into Map Projections and now will finish the discussion with Scale, Reference, and Coordinate Systems.

• Describe 3 ways scale is represented on maps
• Discuss the difference in small-scale and large-scale maps
• Describe why map scale is confusing to most people
• Describe why we need reference systems?
• Name 2 reference systems that are location / map based (not coordinate systems)
• Describe why we use coordinate systems
• Describe the UTM coordinate system
• Describe the UPS coordinate system
• Describe the State Plane Coordinate System
• Describe metes and bounds
• Describe the Public Land Survey System
