|18 Feb 2013||Optimized Pit Removal
Description: ArcGIS (version 10.1) geoprocessing script tools for removing pits (or sinks) from Digital Elevation Models using a combination of cut and fill. This alternative to the standard Fill tool provides more realistic flow paths with less required manual adjustment. Ideal for high-resolution datasets such as LiDAR.
The tool also allows users to mark specific depressions to be left unmodified by setting the lowest cell to have a value of No Data. This feature can be used to establish reservoirs as well as known drainage features such as storm sewer inlets.
Also contains a C++ executable that can be run via command line inputs independent of ArcGIS, and which operates on ASCII grid files.

|21 Jul 2015||TopoToolbox
Description: TopoToolbox is a suite of MATLAB functions for topographic analysis. 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. Key methods include advanced methods of flow direction derivation, stream network extraction and manipulation, slope-area analysis, chiplots, and swath profiles.
