Ce que vous pouvez faire avec vos graphiques

Eh bien, vous pouvez faire tout ce que vous voulez avec vos graphiques, bien sûr. Mais certaines choses que vous n'avez peut-être pas envisagées sont :

• Les auteurs de pages Web peuvent intégrer un graphique des dernières données dans une page Web à l'aide de balises HTML <img>.
• N'importe qui peut utiliser le Trieur de Diapos d' ERDDAP pour créer une page Web personnelle qui affiche des graphiques avec les dernières données (ou d'autres images ou contenu HTML), chacun dans sa propre diapositive déplaçable.

Data will be used to better inform the conversation and solutions around plastic pollution in the region.  The project is funded by Environment and Climate Change Canada and is in partnership with Clean Annapolis River Project (CARP), ACAP Humber Arm, and Dr. Max Liboiron at the Civic Laboratory for Environmental Action Research (CLEAR) out of Memorial University of Newfoundland (MUN).  Dr.  Max Liboiron is our chief academic advisor on the 3-year project, assisting with project development, methods and protocol, and sampling design.  The project included sampling both surface water and beach sediment at all three study locations.  The surface water trawling equipment was built using CLEAR's low-aquatic debris instrument (LADI) design.  This document contains the results from the 2018 surface water samples.  Sediment data results for 2018 and hot-spot data from 2019 will be available in 2020.";

Utilisation de tabledap pour demander des données et des graphiques à partir d'ensembles de données tabulaires

tabledap vous permet de demander un sous-ensemble de données, un graphique ou une carte à partir d'un ensemble de données tabulaires (par exemple, des données de bouée), via une URL spécialement formée. tabledap utilise l' OPeNDAP Protocole d'accès aux données (DAP ) et ses contraintes de sélection .

L'URL spécifie ce que vous voulez : l'ensemble de données, une description du graphique ou du sous-ensemble des données et le type de fichier pour la réponse.

• (facile) Vous pouvez obtenir des données en utilisant le formulaire d'accès aux données ou le formulaire de sous -ensemble de données. Ils font l'URL pour vous.
• (facile) Vous pouvez créer un graphique ou une carte en utilisant le formulaire Make A Graph de l'ensemble de données. Il crée l'URL pour vous.
• (pas difficile) Vous pouvez contourner les formulaires et obtenir les données ou créer un graphique ou une carte en générant l'URL à la main ou avec un programme informatique ou un script.

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.
