"The Brizo is a GNSS-based, directional wave height sensor. Developed by Xeos Technologies, it is a breakthrough product on the market that provides significant wave height, maximum wave height, peak wave period, average wave direction, and average wave spread. It was installed on the HKB navigational buoy in the Halifax Harbour near Meagher's Beach.

When the Port Authority raised a need for capturing wave data at this location, Xeos Technologies was happy to provide and install its own wave height sensor for the SmartAtlantic project. It is an opportunity to aid in the environmental monitoring of harbor conditions.";

Développé par Xeos Technologies, il s'agit d'un produit révolutionnaire sur le marché qui offre une hauteur de vague importante, une hauteur maximale des vagues, une période de pointe, une direction moyenne des vagues et une propagation moyenne des vagues. Elle a été installée sur la bouée de navigation HKB dans le port d'Halifax, près de Meagher's Beach.  \\n \\nLorsque l'administration portuaire a soulevé le besoin de saisir les données sur les vagues à cet endroit, Xeos Technologies était heureuse de fournir et d'installer son propre capteur de hauteur des vagues pour le projet SmartAtlantic. Il s'agit d'une occasion de contribuer à la surveillance environnementale des conditions portuaires.";

Using tabledap to Request Data and Graphs from Tabular Datasets

tabledap lets you request a data subset, a graph, or a map from a tabular dataset (for example, buoy data), via a specially formed URL. tabledap uses the OPeNDAP (external link) Data Access Protocol (DAP) (external link) and its selection constraints (external link).

The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.

Tabledap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
Thus, the query is often a comma-separated list of desired variable names, followed by a collection of constraints (e.g., variable<value), each preceded by '&' (which is interpreted as "AND").

For details, see the tabledap Documentation.
