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.

Description: DielmoOpenLiDAR is an open source software with GNU GPL license based in gvSIG for the management of LiDAR data. It allows access, visualization and analysis of the original LiDAR data, toguether with the possibility of visualizing at the same time big volumes (hundreds of GigaBytes) of original LiDAR data (irregular points in formats LAS and BIN) along with other geographic data. In the near future, it will also generate basic final products such as (DSM, DTM, intensity images, etc) and new added value final products.

Developing open source software for the management of LiDAR data, we hope to make this technology more accessible to standard GIS users and scientific communities, having as final objective increase the use of LiDAR data.

For developing this application, we had the collaboration of the Regional Valencia Council for Infrastructures and Transportation - CIT and National Geographic Institute of Spain - IGN.

Description: The (RBT) is available for free and is under active development. Tools exist for cutting cross sections and longitudinal profiles into high resolution DEMs to extract hydrologic parameters such as wetted area, bankfull width, hydraulic radius, gradient and sinuosity. It is possible to save the cross section properties as a ShapeFile and then add them to a map. Using an automated detrending algorithm we are able to remove the overall valley slope. Tools are being created that use the detrended raster to investigate flooding outside a main channel at any prescribed discharge or flow stage.
