The orthogonal camera view presented here is taken in the nadir direction (vertically downwards) towards the Sheraton boardwalk and its nearshore surroundings. It operated for over 4.5 years between February 5, 2009 and October 13, 2013. Capturing hourly snapshots at a set vantage point during the local daytime hours of 6:00 AM or 7:00 AM to 5:00 PM, these images are useful for tracking beach dynamics such as wave run-up, sand movement, and turbidity plumes over time. The camera was mounted on top of a 3 meter wall extending above the roof surface for a total height of 93 meters above ground level or 96 meters above mean sea level. See also BEACHCAM-001 for an oblique camera view from the same location pointing southeast towards Diamond Head crater.";

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{?query}
For example,,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.
