TOPAZ: Topographic Parameterization
Entry ID: TOPAZ
Abstract: TOPAZ (Topographic Parameterization) is an automated digital landscape analysis tool for topographic evaluation, drainage identification, watershed segmentation and subcatchment parameterization. While TOPAZ is designed primarily to assist with topographic evaluation and watershed parameterization in support of hydrologic modeling and analysis, it also has application to a variety of ... geomorphological, environmental and remote sensing applications.
The overall objective of TOPAZ is to provide a comprehensive evaluation of landscape drainage characteristics while maintaining consistency between all derived data, the initial input data, and the physics underlying energy and water flux at the landscape surface. The analysis is based on the application of the deterministic eight-neighbour (D8) method to simulate flow across a land surface represented by a raster (grid) digital elevation model.
