Description
This course is an introduction to navigation-grade Global Positioning System (GPS) instruments used in agriculture and environmental science. Emphasis is placed on instrument familiarization, field data collection and processing, real-time and post-differential correction, and GPS-GIS integration. The course is designed to be a very practical, hands-on experience with GPS instruments used for field-based survey and mapping of plots, fields, boundary conditions, and other bio-physical features.

Expectations and Responsibilities
Students
are expected to have basic mathematical skills and some experience with
computers and word processing and spreadsheet programs. Students should be able
to communicate to instructors using electronic mail, and to access and search
the Internet for data and information relevant to the course. The goal of the
instructors is to promote an active learning environment in the course which
requires instructors and students to be motivated, participatory, and
communicative. Assignments, projects, and exams are designed to be conducted
independently. Instructors and students are expected to adhere to

Students with Disabilities
Students with disabilities are encouraged to see the instructor in order that course materials may be updated appropriately to better foster the teaching and learning experience.
Schedule
Weather permitting, the course will consist of two 7.5-hour long sessions on March 29 and April 5. The class will be held in Bradfield 108 and outside on the Cornell campus. Dress appropriately.
Computing Resources
All laboratory sections will be held in the Bradfield Computer Classroom, Room 108 Bradfield Hall. The classroom is accessible to students enrolled in the course on scheduled lab days, or as posted in the course schedule. Bradfield Hall is a secured building after 8p. Students are not expected to work in the laboratory during evenings, weekends, or holidays. Assignments are designed to be completed during the normal laboratory period and during open lab periods as posted in the course schedule. Students who need extra time in the laboratory must submit a request to one of the instructors so appropriate arrangements can be made.
