Viewing Data on the Time-Aware Layers

OnPoint web-GIS application supports time-aware layers where you can view data by playing back the temporal progression of that data using a time slider bar. Time-aware layers store information about the changing state of a dataset over time, and allow you to view patterns and trends in your data.

1.	Click the Map Content and Legend button. The Map Content and Legend pane opens.

2.	In the Layers tab, click the Time-Aware button.

•	Click the Pause button to pause the playback.

•	Click the Forward button to view the features in the next time interval.

NOTE:

When you print a map with time-aware layers, only those features in the map are printed that were available for the selected time frame. For example, when you pause a time slider during its progression and print the map, only those features are printed that were visible at the time you clicked the Print button.
