Information About HymosHymos Data StructureHYMOS EnvironmentConnecting Hymos to GISHymos ApplicationsDescription of Hymos

Data TypesMain components of HymosTo Main Menu

Description of Hymos (1/2)Hymos is a powerful information system for storage, processing and presentation of (geo)hydrological, meteorological, water quality and morphological data.

Hymos combines an efficient database structure with an extensive set of tools for data entry, validation, completion, analysis, retrieval and reporting.

Description of Hymos (2/2)Hymos is comprehensive, well tuned and easy to use. A full graphical and map-based user interface creates a pleasant and efficient working environment. Hymos has powerful and flexible modules for production of graphics, maps and tables. The Open Data Structure ensures convenient interaction and data transfer with most other databases and modelling systems operated world-wide. Being part of Delft Tools, Hymos is fully integrated with other software packages of Delft Hydraulics like Sobek, Delwaq and Ribasim.

Hymos runs on stand-alone computers as well as in a network system. Securities have been built in to restrict access to certain activities to qualified staff only.

Hymos ApplicationsHymos is developed for efficient storage, processing and presentation of (geo)hydrological, meteorological, water quality and morphological data. Its features cover the needs of organisations responsible for monitoring network operation and database management like hydro-meteorological services, water resources authorities and water boards. The powerful data processing and analysis features, on the other hand, make Hymos very suitable for application in studies, research and consultancy which often require processing of large amounts of data in a limited time frame.

Hymos data are to a large extent time-oriented. Together with a space oriented GIS, it covers the data storage and processing requirements for planning, design and operation of water management systems.

Hymos EnvironmentHymos uses the win32 API used in Windows 95 en Windows NT for optimal communication with the 32 bits operating system. Through the Microsoft Jet database engine Hymos has direct access to many different relational databases like Microsoft Access and ODBC databases.Hymos is built on the modular structure of Delft Tools (Decision Support System Tools). This allows easy integration of existing applications into Hymos by means of OLE (object linking and embedding) or DDE (dynamic data exchange).

Connecting Hymos to GISBecause Hymos is map oriented it can be easily linked to GIS sytems. At present, the geographical interface for Hymos is Netter, a Delft Tools component. Between Hymos and Netter an OLE connection is established to exchange information.Instead of using Netter you can use your own GIS as an interface to Hymos, like ArcView or MapInfo.

Hymos Data StructureHymos uses two data types:Matrix data: this is time oriented data in equidistant and non-equidistant series. The data is organised as a three dimensional matrix with location, parameter and time axis. This Data structure is file-independent through Open Data Structure library of supported file types. Adding of new file types to the library is very easy.Meta data to give details concerning locations, parameters, time and relations. This meta data uses standard database file formats accessed with the Database engine. Hymos uses the Microsoft Jet database engine to access relational data bases. This enables Hymos to connect to a wide range of data base systems like:Microsoft Jet database file, Access database (.mdb)an ODBC database, such as a Paradox, or ISAM.
