3.11 PPI: Plan Position Indicator
Figure 16 PPI Example Configuration
PPI is a full screen image used primarily for weather surveillance purposes.
PPI shows the distribution of the selected data parameter on a constant elevation angle
surface, the classic radar display. IRIS PPI products are made as soon as the requested
elevation sweep is completed rather than at the end of a volume scan.
A PPI shows data from one elevation, all azimuths. You can use it at the radar site for quality
control.
1. On the IRIS menu, select Menu > Product Configuration .
2. Select Type > PPI.
3. Select the button next to TASK name, and select a task from the list.
4. Select the button next to Data:Display, and select a parameter to be displayed,
typically Z for reflectivity.
5. Enter Maximum Range (km) and elevation angle which suit the task you have selected.
You can see task information in upper part of the menu.
6. Select File > Save as and give a name for the PPI file.
