Name field.
Some data sources can automatically update themselves by selecting
the Active button. For example, if you had a set of most recent
satellite images you can turn on Polling and have the data update to the latest
images every N minutes.
For point data you can define Time Binning settings (not shown) by selecting a Bin Size (e.g., 5 minutes, 1 hour) and a Round To value (e.g., On the hour, 15 minutes after the hour). This will map all the observation times into the nearest bin. The smallest time is rounded with the Round To value (e.g., if Round To was "10 after" and the smallest time was 10:23 then this time would be rounded to 10:20). This is the base time. Each actual observation time is mapped into a set of bins of Bin Size starting at the base time.
Use Default
and Use Selected. Click the drop down menu, choose the Use Selected
menu item and select individual times. You can also right mouse click in the list
to show a popup menu that allows you to select different strides (e.g., every 3rd time).
Match Time Driver and Set As TIme Driver
to allow you to use the time driver times or to set the selected times as the time driver times.
Spatial Subset tab.
The X Stride, Y Stride and Z Stride menus
allow you to decimate a grid, selecting every Nth point.
The Bounding Box allows you to define a spatial area to load.
The default spatial domain of the data is shown by the blue outline box.
To select an area just drag on the map. Once a subset is selected it can be
resized (grab on the little black selection points) moved (grab somewhere near the
box) and delete (press the Delete key).
Specific lat/lon values can be entered in the fields on the left.
