griddap lets you request a data subset, graph, or map from a gridded dataset (for example, sea surfacetemperature data from a satellite), via a specially formed URL. griddap uses theOPeNDAP
Data Access Protocol (DAP) and its projection constraints.

- (easy) You can get data by using the dataset's Data Access Form. It makes the URL for you.
- (easy) You can make a graph or map by using the dataset's Make A Graph form. It makes the URL for you.
- (not hard) You can bypass the forms and get the data or make a graph or map by generating the URL by hand or with a computer program or script.
griddap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/griddap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/griddap/jplMURSST41.htmlTable?analysed_sst[(2002-06-01T09:00:00Z)][(-89.99):1000:(89.99)][(-179.99):1000:(180.0)]
Thus, the query is often a data variable name (e.g., analysed_sst),followed by [(start):stride:(stop)](or a shorter variation of that) for each of the variable's dimensions(for example, [time][latitude][longitude]).
