WHOS is the WMO Hydrological Observing System. These pages collect short technical guides and tutorials to ease end user and developers interactions with WHOS. Example given it is documented how to search and access datasets from WHOS using the supported tools and libraries.
Each tool requires specific service and format standards, that are provided in the background by a brokering framework maintained by CNR-IIA that empowers WHOS, by acting as a middleware: the broker mediates and harmonizes search and access functionalities that are in the first place provided by the heterogeneous data providers that compose the WHOS system of systems.
WHOS offers many views, corresponding to subset (portions) of the entire hydrological information globally available. Views are defined on a given area or temporal extent, or on a particular subject (e.g. discharge parameter).
Each view can be accessed by means of different clients, corresponding to the standard protocol interfaces published by the broker. Same major views include:
- La Plata river basin
WHOS - supported clients
Here is an updated list of known tools and libraries capable of search and access hydrological time series offered by WHOS. Detailed instructions on how to use them to access the available WHOS views are given in separate pages.
Node.js WaterML client
GI-suite JS API
R WaterML library
C# library provided by WCF Data Service Template plugin
Your own application / library
Let us know what are the applications and libraries you are using in every day work as an hydrologist. We can work to have it added to this list. As a result, you will be able to integrate data coming from WHOS directly in your tool.
