Data Collection and Manipulation
Data collection is the largest part of any GIS project, and it is the first step in monitoring and assessing goose damage on grain/seed yield. Data collection is the process of gathering pertinent information about a farm field, including any factors that may hinder plant growth.
The required data will be obtained from several sources. The majority of the information is collected on the farm with a GPS unit, and the additional data is available from private and public sources. The Internet is quickly becoming a repository for much of this data, some of which is free. The data collection process is diagramed below ( Figure IIA-2) .
