Features and Limitations

Input Data

CatchmentSIM uses a raster DEM as the foundation for its hydrologic analysis. A raster DEM can be created from a wide range of GIS data including:

Vector files (such as contours) in ESRI Shape file (*.shp), MapInfo Exchange file (*.mid/mif) or 12D ASCII (*.12da).
Raster DEMs in a range of formats including ASCII Grid, Arc Binary (*.hdr), Arc Raster (*.adf), AIRSAR Polarimetric, VTP Binary Terrain (*.bt), Military Elevation Data (*.dt0, .dt1, .dt2), GMT Compatible netCDF, Golden Software Grid, Grid Exchange File (*.gxf), SRTM HGT (*.hgt), Japanese DEM (*.mem), NED DEM, USGS ASCII DEM (*.dem), USGS SDTS DEM (*.cadt.ddf), Terragen Heightfield and others.
Triangular Irregular Network (TIN) DEMs (Arc/Info ASCII Net (*.net), 12D ASCII (*.12da) format)
Spot Heights in comma, space or tab delimited X Y Z format.
Triangular Irregular Networks (TIN) in ASCII-NET format.
LiDAR (*.las) data files.

CatchmentSIM also supports a wide range of raster imagery including internal geo-referencing. Supported image formats include ERMapper Compressed Wavelets (*.ecw), MrSID (*.sid), TIFF and GeoTiff (*.tiff), JPEG (*.jpg), JPEG 2000 (*.jp2, *.j2k), Graphics Interchange Format (*.gif), Portable Network Graphics (*.png), Windows Metafile (*.wmf), Windows Bitmap (*.bmp), ADGR/ARC Digitized Raster Graphic, USGS DOQ (*.doq), Intergraph Raster, IRDAS Imagine (*.img), IDRISI Raster, SGI Image Format (*.sgi) and others.

Output Data

Once subcatchment boundaries have been defined and the associated hydrologic characteristics have been calculated, the information can be exported to external GIS applications. CatchmentSIM supports export to the following vector and raster file formats:

ESRI Shape (*.shp)
MapInfo Exchange (*.mid/mif)
Common grid formats including Arc/Info ASCII / Binary Grids
Keyhole Markup Language - Google Earth (*.kml).

In addition, the subcatchment boundaries and hydrologic parameters can be exported to a standard results file format for reporting or a third party hydrologic computer model input file format for further detailed analysis. CatchmentSIM includes a flexible result export language called CST which can be used to export project results in any file format. This is achieved by selecting from one of the available macro scripts distributed with the program or writing your own. Providing you have information on the input file format of the desired model, the CST language provides the tools needed to export almost any CatchmentSIM project values (e.g., areas, % impervious, runoff curve numbers) in the required file format and structure.

Caution Notes For User

Garbage in = garbage out :)
