The Global Positioning System (GPS) is an important tool for natural resource managers. Wildlife biologists use GPS to document the location of nests, survey points, and other critical habitats. Foresters use GPS to delineate treatment areas and develop standard geographic information systems (GIS) databases for roads and other management-related infrastructure. Fisheries biologists and hydrologists use GPS to map stream systems. Recreation resource managers use GPS to map trails systems. A variety of professional use GPS in conjunction with wildfire monitoring and suppression activities. All natural resource managers, along with the general public, use GPS to navigate. While most people think of GPS in terms of the receivers that they use, GPS is actually a system of satellites, receivers, control stations, base stations, and software for navigation and mapping the earth's features. This two-day course:
- Introduces the basic features of the Global Positioning System
- Discusses sources of error and techniques for assessing data quality
- Provides experience with GPS mission planning, GPS data collection, and post-processing GPS data
-
Upon completion of this course, you should be able to:
- Understand the basic components of GPS
- Be able to understand many of the common terms associated with GPS (e.g., PDOP)
- Think critically about GPS error sources and data quality
- Understand how to plan and conduct a data collection project with a mapping-grade GPS receiver

Natural resource management professionals and realtors who have little or no background with the Global Positioning System (GPS), yet have an interest in learning about the basics of GPS and experiencing data collection procedures, post-processing procedures, and accuracy assessment methodology. Upper-level managers who need to communicate GPS-related requests with field personnel may find the course useful as well. Realtors who are involved in the valuation of rural land and timber should also attend.

This course provides lecture material, computer-based exercises, and field data collection exercises to provide an overview of GPS and experience in various phases of GPS use in natural resource management. The material will be presented in a logical manner, from a description of GPS, to the equipment involved, to field data collection procedures. These all occur on Day 1. On Day 2, data collected in the field will be transferred to a computer, differentially corrected, and displayed in a geographic information system. Accuracy will be assessed. Handouts will be provided to summarize the material presented.

Pete Bettinger is an associate professor in the Warnell School of Forestry and Natural Resources. He has more than 20 years of operating, teaching, and research experience in forestry and natural resources, including roles with the U.S. Forest Service, several forest products companies, and Oregon State University. Bettinger has taught several courses on forest measurements, forest planning, and harvest scheduling, as well as GIS applications in natural resource management. In 2004, McGraw-Hill published his book Geographic Information Systems: Applications in Forestry and Natural Resources Management. Bettinger earned BS and MS degrees from Virginia Tech; and a PhD from Oregon State University.
