Introducing Geographic Information Systems with ArcGIS: A Workbook Approach to Learning GIS, 3rd Edition

Environment and Measurement (Spatial Data)

• Use the back wall of the lab as southern latitude.
• Use a Cartesian coordinate system.
• Consider the intersection of the back wall and the “west” wall as the Cartesian point (1000,2000).
• For each location’s easting, measure perpendicularly from the west wall to the center of the cross on the sticky note.
• For each location’s northing, measure perpendicularly from the south wall to the center of the cross on the sticky note.
• Measure to the nearest 0.01 (one hundredth) of a foot.
