The grid animation controls allow you to view grids (precipitation, snow water equivalent, temperature, etc.) for the time window you have chosen. The controls are located on the Animate dialog which is accessible from the Visualization Module. Choose Animate from the View menu to display the Animatedialog. The dates above the slider bar show the start and end time of the grids that are visible in the display window. The date and time shown beneath the centered controls indicate the date and time of the data currently being displayed. A slider bar and buttons control animated playback. The sliderallows you navigate the active grid set for a specific time during the time window. With these playback controls, you can play an animation of the active grid set from the beginning to the end of the Visualization time window.
The buttons function as follows:
Skip to Beginning - sets the slider at the beginning of the time window and displays the status of data at that time
Step Back - steps the image back one time interval
Pause - pauses playback
Stop -stops playback
Play - plays the animation, one time interval at a time, starting at the location of the slider
Fast Forward - plays through the animation in fast forward mode
Step Forward - steps the image forward one time interval
Skip to End - moves the slider and the image to the status at the end of the time window
In order for playback to occur, you must define the coordinate system for both the watershed layers and the grid set, and there must be data present for the time window specified. If no grid is available for the time step, the label centered over the grid animation controls will end with No Data.
The recommended naming convention for gridded HEC-DSS files is attribute.YYYY.MM.dss as the date will be dynamically updated by the CAVI. Example: precip.2023.05.dss would hold all the precipitation data for May of 2023.
