XMDF
XMDF (eXtensible Model Data Format) is a library providing a standard format for the geometric data storage of river cross-sections, 2D/ 3D structured and unstructured meshes, geometric paths through space, and associated time data. XMDF uses HDF5 for cross-platform data storage and compression. It was initiated in Engineer Research and Development Center ( ERDC) and is developed by Aquaveo (formerly the Environmental Modeling Research Laboratory (EMRL) at Brigham Young University). API includes interfaces for C/C++ and Fortran. An overview of the format was published by the ERDC in 2007. More recent documentation is available online at https://www.xmswiki.com/wiki/XMDF. A binary format was chosen for the data in order to improve performance and data storage as compared with more traditional ASCII grids. The group considered both the NetCDF and HDF5 data formats, and chose HDF5 because it has more flexibility for data storage, compression and data mining. It also supports da ...

Aquaveo
Aquaveo is a Computer simulation, modeling software company based in Provo, Utah that develops software used to model and simulate groundwater, Drainage basin, watershed, and surface water resources. Its main software products include SMS (hydrology software), SMS, GMS (software), GMS, WMS (hydrology software), WMS, and Arc Hydro Groundwater. History The Engineering Computer Graphics Laboratory (ECGL) was established in 1985 at Brigham Young University (BYU). Simulation data produced in the lab was critical to ''Anderson v. Cryovac, Inc.'', a 1986 federal lawsuit concerning toxic contamination of groundwater in Woburn, Massachusetts. After using another BYU product—Movie BYU—to animate a hydrology problem to make it easier to understand, Norm Jones decided to start work on software that helped engineers visualize problems and solutions. Use of the tools created by Jones allowed the U.S. Army Corps of Engineers to save "hundreds of thousands of dollars". Alan Zundel and James N ...

NetCDF
NetCDF (Network Common Data Form) is a set of software libraries and self-describing, machine-independent data formats that support the creation, access, and sharing of array-oriented scientific data. The project homepage is hosted by the Unidata program at the University Corporation for Atmospheric Research (UCAR). They are also the chief source of netCDF software, standards development, updates, etc. The format is an open standard. NetCDF Classic and 64-bit Offset Format are an international standard of the Open Geospatial Consortium. The project started in 1988 and is still actively supported by UCAR. The original netCDF binary format (released in 1990, now known as "netCDF classic format") is still widely used across the world and continues to be fully supported in all netCDF releases. Version 4.0 (released in 2008) allowed the use of the HDF5 data file format. Version 4.1 (2010) added support for C and Fortran client access to specified subsets of remote data via OPeNDAP. Ver ...

CGNS
CGNS stands for CFD General Notation System. It is a general, portable, and extensible standard for the storage and retrieval of CFD analysis data. It consists of a collection of conventions, and free and open software implementing those conventions. It is self-descriptive, cross-platform also termed platform or machine independent, documented, and administered by an international steering committee. It is also an American Institute of Aeronautics and Astronautics (AIAA) recommended practice. ThCGNS projectoriginated in 1994 as a joint effort between Boeing and NASA, and has since grown to include many other contributing organizations worldwide. In 1999, control of CGNS was completely transferred to a public forum known as thCGNS Steering Committee This Committee is made up of international representatives from government and private industry. The CGNS system consists of two parts: (1) a standard format (known as Standard Interface Data Structure, or SIDS) for recording the data, ...

Scientific Data Format
This is a list of file formats used by computers, organized by type. Filename extension it is usually noted in parentheses if they differ from the file format name or abbreviation. Many operating systems do not limit filenames to one extension shorter than 4 characters, as was common with some operating systems that supported the File Allocation Table (FAT) file system. Examples of operating systems that do not impose this limit include Unix-like systems, and Microsoft Windows NT, 95- 98, and ME which have no three character limit on extensions for 32-bit or 64-bit applications on file systems other than pre-Windows 95 and Windows NT 3.5 versions of the FAT file system. Some filenames are given extensions longer than three characters. While MS-DOS and NT always treat the suffix after the last period in a file's name as its extension, in UNIX-like systems, the final period does not necessarily mean that the text after the last period is the file's extension. Some file formats, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

C (programming Language)
C (''pronounced like the letter c'') is a General-purpose language, general-purpose computer programming language. It was created in the 1970s by Dennis Ritchie, and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs. It has found lasting use in operating systems, device drivers, protocol stacks, though decreasingly for application software. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the measuring programming language popularity, most widely used programming languages, with C compilers avail ...

HDF5
Hierarchical Data Format (HDF) is a set of file formats (HDF4, HDF5) designed to store and organize large amounts of data. Originally developed at the U.S. National Center for Supercomputing Applications, it is supported by The HDF Group, a non-profit corporation whose mission is to ensure continued development of HDF5 technologies and the continued accessibility of data stored in HDF. In keeping with this goal, the HDF libraries and associated tools are available under a liberal, BSD-like license for general use. HDF is supported by many commercial and non-commercial software platforms and programming languages. The freely available HDF distribution consists of the library, command-line utilities, test suite source, Java interface, and the Java-based HDF Viewer (HDFView). The current version, HDF5, differs significantly in design and API from the major legacy version HDF4.
