Upgrading of the User Interface

•CatchmentSIM now utilises an updated splash screen that provides instantaneous access to create a new project, open your last used projects, and incorporates a preview image of the project, right there on the splash screen.

•Important CatchmentSIM related news is readily provided to ensure you are up to date with everything CatchmentSIM.

•Resources for online help and mail support are also readily accessible.

Multi Resolution Valley Bottom Flatness (Mr VBF) Algorithm

•This advanced spatial analysis algorithm provides an excellent indication of flatness which can be useful for hydrologic model input.

Spatially Balanced Sampling Site Selection

•Undertake a spatially balance sample site selection for resource monitoring projects with the ability to achieve desired distributions against certain categories (such as Horton Order).

More flexible addition and editing of subcatchment outlets

•Ability to add an alignment as an outlet where outlets will be automatically added along the alignment based on a stream area threshold (useful, for example, when planning the position of culverts along a road or rail alignment)

•Ability to add an ocean polygon as an outlet, allowing coastlines to be identified as outlets instantaneously

•Greater flexibility when editing outlets, notably in deleting outlet pixels, and creating a new outlet from selected outlet pixels.

Subcatchment Manager Updates

•The subcatchment manager now allows selection of multiple subcatchments, and provides the option to merge and delete multiple subcatchments.

Greater usability and manipulation of Grids

•CatchmentSIM now allows the editing of grid cell values directly from a CST script, ability to undertake accumulation, similarity, and connectivity calculations on any grid layer, as well as allowing DEM smoothing.

New Stream Initiation Methods

•In addition to creating a stream network based on a Stream Area Threshold (SAT), you can now create streams based on the stream initiation of an observed stream network (such as a stream GIS layer) or a grid based initiation parameter (for example, allowing a different SAT for different soils)

Support for additional Vector Formats

•Support (read only) for new vector file formats including DXF (AutoCAD), E00 (ESRI) and others.

Speed Improvements

•Official release of the multi-threading ability for DEM interpolation and Catchment Mapping (activated through project options), providing a 300% increase in speed of the before-mentioned processes.

Normalised Area Function Chart

•A new chart has been added to CatchmentSIM called the Normalised Area Function. This is the distribution of flow path lengths to the catchment/subcatchment outlet. This chart is parameterised by the Average Flow Path Length and Maximum Flow Path Length (already existing) and one new parameter, Standard Deviation of Flow Path Lengths in the Subcatchment Manager Form

Numerous Other New Features including

•Create Contours from any grid (including DEM)

•Calculate Subcatchment Width.

•Integrated bug tracking and version update notifications.

•Lots of bug fixes.
