Topo工具箱包含一组为非地理信息系统(GIS)环境中的地貌分析提供实用程序的MatLab函数。开发这些工具是为了支持空间和非空间数值分析相结合的工作流程。它们为水文和地貌研究提供了灵活和用户友好的软件，涉及数字高程模型分析，并侧重于水、沉积物、化学物质和营养物质的物质通量和空间变异性。本文的目的是介绍采用稀疏矩阵计算进行数字高程模型分析的软件背后的线性代数概念。此外，我们还概述了工具箱的功能。这些源代码可以在作者的网页(Physiogeo.unibas.ch/topoToolbox)上以MatLab语言免费获得。(C)2009爱思唯尔有限公司。保留所有权利。
TopoToolbox contains a set of Matlab functions that provide utilities for relief analysis in a non-Geographical Information System (GIS) environment. The tools have been developed to support the work flow in combined spatial and non-spatial numerical analysis. They offer flexible and user-friendly software for hydrological and geomorphological research that involves digital elevation model analysis and focuses on material fluxes and spatial variability of water, sediment, chemicals and nutrients. The objective of this paper is to give an introduction to the linear algebraic concept behind the software that employs sparse matrix computations for digital elevation model analysis. Moreover, we outline the functionality of the toolbox. The source codes are freely available in Matlab language on the authors' webpage (physiogeo.unibas.ch/topotoolbox). (C) 2009 Elsevier Ltd.
