Multiple products can be overlaid in this manner. For example, WIND and SLINE displayed
together show the wind vectors associated with a shear line.
Product overlays have time alignment options:
• Nearest
The overlay product is the nearest in time to the base product.
• Live
The overlay product is the most recent time.
It is also possible to combine 2 dierent types of image products. The example above shows
VIL product with TOPS displayed underneath.
When combining 2 image products, it is important to select contrasting color scales to be
able to separate the data. In this example a gray scale was used for the TOPS. The drop
shadows on the VIL are helpful.
If your IRIS system supports satellite IMAGE product ingest, then this is how you combine
the satellite display with radar data.
Range Units
This allows you to select range units for output displays. Choices are: scientific (kilometers)
or navigational (nautical miles for horizontal distances and kilofeet for altitudes).
Time
This allows you to display UTC or the local time on the legend. The time has a Z sux if it is
UTC.
Select Default to let the Setup question to control this value.
