the landscape? Third, data can be transformed into information that fits a user’s context through a rich set of analytical tools. The relationship between different attributes can be examined to investigate, for example, the spatial arrangement of aspen clones with respect to soil type, aspect, or time since disturbance. Fourth, geographic data in a GIS do not suffer, as they do in paper maps, from the fundamental trade-off between spatial detail and geographic coverage (although because most geographic data are derived from paper maps, they typically can only represent features to a certain resolution). This is because the scale of a map can change depending on user needs, yet the underlying data remains the same.
