Part II
	Tasks Performed by Providers

Part II describes procedures that will typically be provided by a technical assistance provider with computer skills - particularly GIS (Geographical Information Systems) applications. Procedures described in this section include building base maps, developing various GIS data layers (goose grazing, soil type, water impacts), and analysing yield data. Data analysis is discussed in section A, which also includes a discussion of how base maps are created. Section B describes how a GPS works, compares different types of GPS, and what information should be collected.

Section A: Using GIS Technology
This section establishes a base of knowledge about the use of Global Positioning Systems (GPS), Geographic Information Systems (GIS), and Yield Mapping System (YMS) as tools for collecting and analyzing data for quantifying the impact of goose on crops.

Section B: Using GPS Technology
Relatively inexpensive GPS receivers like those used by pilots, boaters and outdoor enthusiasts can determine its position on the Earth's surface to within a few meters. With more sophisticated receivers and data-analysis techniques, we can determine receiver positions to less than a centimeter.
