Inter- and Intranet Access on WISKI DataWater Resources Management System KISTERS - the Water Resources Information System"
WISKI Web is a scalable system for the visualisation of time series data via internet technology.
WISKI Web shows the data in the form of lists, maps, graphs, and tables and allows information to be downloaded in various formats (CSV, Excel, Word, PDF).
WISKI Web can be obtained from KISTERS in three varieties (where the third called WISKI Web Online is an add on to WISKI Web Pro).
WISKI Web Pro
allows user interactions in extensive way (free speci-fication of time periods, filter criteria, etc). Direct database access is necessary because WISKI Web answers every request dynamically and on demand. WISKI Web uses PHP for database requests and an-swers requests from the browser in HTML-format.
Because of the extensive user functionality WISKI Web Pro is commonly used for internal purposes (Intranet) but could also potentially be applied for external use. In this case we would recommend that a web-database be created, which is a standby copy from the main database.
WISKI Web Public
consists of a dedicated amount of pages, graphs, and tables; this system allows user interactions by providing hyperlinks and predefined specifications of input parameters. WISKI Web Public only needs direct access to the database for internal actions. The WISKI Service Provider periodically requests the internal web pages, converts these pages and transfers them to the public internet server's file system. Consequently the pages represent current data. The web server serves static files and is able to serve large amounts of public requests which arise in flood situations.
WISKI Web Online
is a system for restricted user groups with focus on the most current data and administration visualisation of status information. The module is tough coupled to the WISKI Alarm Module, where warning levels and related actions can be entered.
The Online system uses a tree structure to organise the station data in parameter groups (physical, chemical, ….) or according to the river network or the data provider. At each place (tree, value list, map) specific status information is represented by colored text or symbol backgrounds.
