1 | Optimized Pit Removal | 18 Feb 2013 | DEM Analysis | |
Keywords: Pit Removal, Sink Removal, Fill, Cut, Hydrologic Conditioning, Flow Direction, Flow Accumulation
License: BSD license 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. |

2 | TopoToolbox | 21 Jul 2015 | Visualization, DEM Analysis | |
Keywords: MATLAB, tectonic geomorphology, DEM analysis
License: BSD license 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. |
