This two week long workshop provided science instructors from throughout the country a chance to experience with the Geographic Information System(ArcView). Throughout the workshop participants shared, learned, and developed a better understanding of the the capabilities of GIS.
GIS is a highly developed graphic software that allows the user to create an extensive database. The development of a database allows the user to begin asking spatial questions about relationships that exist between different layers of data. Data is portrayed in three different forms: POINT, LINE, and POLYGON.
