An Association Rule Discovery System Applied to Geographic Data
- 428 Downloads
An association rule discovery system has been developed for geographic data. Association rules are applicable to the interpretation of remote sensing images, in which rules derived from another data set can provide ancillary data to guide land cover mapping. The software system developed, called Aspect, works with standard geographic data formats and extends the association rule formulation to handle spatial relationships. Multiple strategies provide guidance for selecting the relevant variables to include in the rules. Association rule results are presented that are derived from environmental conditions, anthropogenic features, land cover, and vegetation.
