TopoToolbox provides a set of Matlab functions that support the analysis of relief and flow pathways in digital elevation models. The major aim of TopoToolbox is to offer helpful analytical GIS utilities in a non-GIS environment in order to support the simultaneous application of GIS-specific and other quantitative methods.
TopoToolbox enables calculation of standard terrain attributes such as
- local topography
flow related terrain attributes such as
- drainage basin delineation
- flow accumulation
- flow distance
stream network analysis such as
- stream order
- slope-area plots
Moreover, TopoToolbox contains several tools to modify stream networks in an automated way and derive swath profiles, among other tools. The algorithms are fast and can thus be used in spatially distributed, dynamic modelling approaches in hydrology, glaciology and geomorphology.
