# GIS 121 - Georeferencing & Mapping

Asheville - Buncombe Technical Community College

This course introduces coordinate systems, fundamentals of surveying, and cartography. Topics include the theory, acquisition, and use of locational data using both continuous and discrete georeferencing methods. Upon completion, students should be able to identify appropriate coordinate systems for a situation and translate data into correct map form.

**Final Project**

What would you like to do for the final project? Next week bring an idea for what you may do.

Please bring - to turn in - the following:

- A short description of the project - a paragraph at most. Include the topic and make sure to discuss the final medium you hope to use, size of map and scale.
- A list of potential data sources - actually research them.

### 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

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.

LEARNING OBJECTIVES

- 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

- map scale
- representative fraction
- verbal statement of scale
- graphic scale
- reference system
- coordinate system
- plane coordinates
- cartesian coordinates
- UTM
- SPCS
