TOPAZ Cover Page


TOPAZ is a software system for automated analysis of landscape topography from digital elevation models. The primary objective of TOPAZ is the rapid and systematic identification and quantification of topographic features in support of investigations related to land-surface processes, hydrologic and hydraulic modeling, assessment of land resources, and management of watersheds and ecosystems. Typical examples of topographic features that are evaluated by TOPAZ include terrain slope and aspect, drainage patterns and divides, channel network, watershed segmentation, subcatchment identification, geometric and topologic properties of channel links, drainage distances, representative subcatchment properties, and channel network analysis.
