The powerful tools of GIS can easily lead to misinformation 
and misinterpretation, particularly by someone unfamiliar with 
their use. Ecological fallacies, problems of scales, and 
propagation of error are frequent, and should be given serious 
consideration. GIS is not a magical solution to all the 
information difficulties, but is a powerful tool capable of 
transforming the way with which information is dealt.

4 Method: Researchers attached satellite and radio transmitters to free-ranging elephants in Cameroon. The equipment 
monitored the elephants' activities during a five-year time span, providing data that recorded and analyzed to 
determine each herds habitat requirements and movement patterns. Radio transmitters allowed wildlife biologists to 
follow the elephants on the ground in the study areas. 
These data have been used to formulate strategies that allowed both elephants and people to maximize their sustainable 
use of these land areas. Data on the elephants ’ movements have been sent to WWF-Cameroon where it will be used to 
document the elephants' travel patterns and land use. This data will then be interpreted to identify areas where 
elephants should be protected and to develop strategies to assist elephants living outside of protected areas.
