Animation Basic Features

This interface is used to control basic display for time-varying Web Mapservice (WMS-T) data layers as timeseries animations. WMS-T data layers are either provided with a list of available times, or have a defined data source interval. The interface will be slightly different depending on the WMS-T data layer format

List of available times

For WMS-T layers that have a list of available times:
Refresh Times: click this button to fetch the most recent available times from the data publisher (as a get capabilities request). This is important for actively updated WMS-T layers like weather.
From and To: these options will each have a dropdown containing the timestamps for all temporal points in the data layer timeseries. Choose a start (From) and end (To) entry to define the beginning and end of the animation loop.
Refresh Rate: this is the frame rate, or time between requests to update the display. Set to a smaller number to view more as a movie, or a larger number to inspect each image more closely.

Play/Pause: clicking this icon with start and pause the animation.
Refresh: clicking this icon will reset the interface inputs.
Displayed date and time: in the bottom left you will see the date and time of the current image displayed.

Data source interval

For WMS-T layers that have a defined data source interval:
Refresh Times: click this button to fetch the most recent available times from the data publisher (as a get capabilities request). This is important for actively updated WMS-T layers like weather.
From and To: these displays will indicate the time window for the layer timeseries.
Data Source Interval: this is the time interval for available data (e.g., 'PT24H' indicates that daily data [every 24 hours] is available).
Start Date/Time: indicates the timestamp for the initial image to be displayed in the animation loop.
Request Interval: this is the interval of the requested data. This interval should be a multiple of the 'Data Source Interval'.
Refresh Rate: this is the frame rate, or time between requests to update the display. Set to a smaller number to view more as a movie, or a larger number to inspect each image more closely.

Play/Pause: clicking this icon with start and pause the animation.
Refresh: clicking this icon will reset the interface inputs.
Displayed date and time: in the bottom left you will see the date and time of the current image displayed.
