Surface structures and tiered topography
10.1002/env.766.abs
The use of contemporary spatial analysis systems for environmental monitoring tends to promote an emphasis on high versus low areas in surface data. However, locally elevated areas as summits or domes may be important even if higher levels are found elsewhere. Also, trends on the periphery of elevated areas can be informative. Some elevated areas drop precipitously on the edges, others drop gradually, and still others have proximate reversals of decline leading up again to other areas that are elevated in greater or lesser degree. The reversals of downward trend may be small and subtle or sustained as major features of the surface. Small reversals having high spatial frequency can be considered as a type of noise engendering local uncertainty for which suppression may be advantageous. Mapping and characterizing these transitional areas leads to major opportunities for etiology since these are zones in which causal factors are also varying and thus relatively amenable to study. Echelon analysis and dome domains enable systematic investigation of spatial trends that would otherwise be difficult. Biodiversity of fish species richness and topographic analysis in Pennsylvania provide contexts for consideration and generalization. Copyright © 2006 John Wiley & Sons, Ltd.
