Simulating environmental effects
The National Forest Service was offered a land swap by a mining company seeking development rights to a mineral deposit in the Prescott National Forest of Arizona. Using a GIS and a variety of digital maps, the USGS and the Forest Service created perspective views of the area to depict the terrain before and after mining.
Existing digital data were combined in a GIS and displayed using a function that creates perspective drawings.
The mining company provided planimetric (two-dimensional) drawings of the proposed mine.
This plan was digitized, along with elevation information on the proposed mine and associated piles and ponds. The resulting perspective view illustrates the dramatic changes to the topography that mining would cause.
A GIS can combine map types and display them in realistic three-dimensional perspective views that convey information more effectively and to wider audiences than traditional, two-dimensional maps.
