Diablo Valley College Course
GEOG-129: Field Data Acquisition and Management 
 
Description
This course covers the fundamentals of the Global Navigation Satellite System (GNSS) using the Global Positioning System (GPS), for data acquisition, management, and integration of data with Geographic Information Systems (GIS). Students will learn to design, implement, manage a field project, and export the information to a compatible GIS platform for advanced analyses.

    1. GPS and navigational satellites
    2. Components of GPS
    3. Use of GPS in the field – benefits and challenges
  2. Designing a project for field data collection
    1. Select a subject and area
    2. Determine the variables to be surveyed
    3. Create a project-plan and time-line
  3. Preparing for field data collection
    1. Understanding the GPS receiver
    2. Setting the coordinate and datum
    3. Creating a data dictionary
    4. Conducting field work
  4. Post-processing field data
    1. Determining acceptable Dilution of Precision (DOP) and positional accuracy
    2. Analyzing error
    3. Preparing the data for integration with GIS
    4. Building the metadata
  5. Future trends in field data collection
 
 
Methods
Lecture, Demonstration, Discussion, Distance Education 
 
Assignments
Reading 1: Read the chapter on metadata. Create a metadata to map the trees in your neighborhood. 
Reading 2: Read the chapter on data transfer and data export. What potential errors and problems can occur while exporting data from GPS into a GIS system? 
Writing, problem solving, performance 1: Using the metadata developed for mapping the utilities at Diablo Valley College, map the utilities of parking lots 3, 4, and 4a. 
Writing, problem solving, performance 2: Using the United States Coast Guard website, differentially correct the data you collected for the assigned project. 
 
Evaluation
Sample One: List one alternative method of acquiring line information in the field without using the line data option in the GPS receiver. 

Sample Two:

When preparing to differentially correct field position data, what is the maximum allowable distance between the base station and the field (rover) unit?

 

Frequency of Evaluation:

Evaluations will adhere to the DVC "Fairness in Grading" guidelines and will include as a minimum:

  • Evaluation of students within the first quarter of the course and notifying student of the results

  • Counting a final examination for no more than one-half the course grade

  • Basing final grades on at least three students' tests and/or reports
