HEC-DSSVue (Hydrologic Engineering Center's Data Storage System Visual Utility Engine)

Criterion	Explanation
General Description	HEC-DSSVue is a graphical user interface program for viewing, editing, and manipulating data in the HEC Data Storage System (HEC-DSS) database files. HEC-DSS is a database system designed to efficiently store and retrieve scientific data that is typically sequential, including time series data, paired data, and spatially oriented gridded data.
Model Domain	N/A
Developer	U.S. Army Corps of Engineers' Hydrologic Engineering Center (HEC)
Hardware computing requirements	Supported systems include Microsoft Windows and Unix. It is also available for Linux.
Code language	HEC-DSSVue was written using the Java programming language.
Original application	HEC-DSS originated at the Hydrologic Engineering Center in 1979. Since that time, many have worked on the development of the HEC-DSS software and the HEC-DSS utility programs, including private consultants.
Public/proprietary and cost	The software is available to the public at no cost. It is not known whether the source code is available to the public.
Physically or empirically based	N/A
Mathematical methods used	HEC-DSSVue can apply the following types of mathematical functions: arithmetic, general (such as units conversion or round-off), time functions, hydrologic functions, smoothing functions, and statistics functions.
Input data requirements	The input data is a HEC-DSS database file.
Outputs	The software can export text files, Excel files, image files, and plot files.
Pre-processing and post-processing tools	N/A
Representation of uncertainty	Uncertainty analysis is not integrated into the modeling framework.
Prevalence	The software is used extensively in the public and private sectors.
Ease of use for public entities	There are no barriers to the widespread use of HEC-DSSVue. The software is well-documented and widely used.
Ease of obtaining information and availability of technical support	A comprehensive User's Manual is provided with the software. HEC can only provide technical support for this software to Army Corps of Engineers users. However, third-party vendors are readily available to provide paid support for use of the software.
Source code availability	Unknown
Status of model development	The software is mature.
Challenges for integration	The use of scripts and plug-ins make HEC-DSSVue a flexible tool for integration.
