Chapter 7: Capturing Absolute Location with the Global Positioning System
Capturing Absolute Location with the Global Positioning System
This chapter includes:
- Geolocation with trilateration
- Five practice exercises on GPS data on the internet
This chapter is the first of several in which you will begin working with geodata. Each of the remaining chapters in Part Two will introduce new tools for collecting absolute and relative location and will provide examples of how these tools can be used to incorporate geodata into your research. Links to the necessary software downloads, sample datasets, and examples of online data repositories will be provided. In this first “hands-on” chapter, we will briefly examine how absolute location data are produced by the Global Positioning System and look at some of the ways in which such ...
