Acquiring and Integrating Geospatial Data

Lesson 7: Integrating GPS Data


Introduction: Acquiring and Integrating GPS Data

A. Goals

Upon completion of module 7, you will be able to recognize the accuracy of different grades of GPS receivers, explain the basics of how a GPS works, use a GPS to acquire your own data, explain how hand-held field units can be used for data acquisition, outline various data creation methods, and describe what's involved in publishing data.

B. Background

Until now we've been focusing on the acquisition of data that already exist. Your assessment of data in your project may have yielded a need for some new data layers. Depending upon the scale of your project, data you acquire with a basic, non commercial-grade GPS receiver may or may not meet your project specifications. For the purposes of getting practice with acquiring GPS data and integrating them into GIS, we will assume that the accuracy of a handheld recreational-use receiver is adequate for your needs.

C. Module Overview

  1. Recognize the accuracy of different grades of GPS receivers (recreational, mapping, surveying)
  2. Explain how GPS works
  3. Use a GPS to find a Geodetic monument
  4. Explain how hand-held field units can be used for data acquisition, ex. ArcPad
  5. Outline various data creation methods
