How can I choose the best beam for covering an area?

It will depend on your application criteria.

This can be seen under the Tools menu and opening the Selection Criteria submenu.

The first, by default, criterion is to Maximize Area Coverage in which steering and swath optimization will maximize the Area of Interest coverage for candidate acquisition.

The second is to Minimize Observation angle. In this case, the lowest observation angle (that is, the beam closest to nadir) is chosen. This is used in many cases in order to have images viewed from a more vertical position and not from a slant which introduces distortion and other inaccuracies.

Then, there is the possibility to Maximize Observation angle, for example for SAR apllications.

And what if I have many acquisitions, such as with a large area or many areas?

Fortunately, there is a function called Auto-Steering which takes this tedium away by applying the selection criteria to each and every acquisition.
Under the Tools menu, we turn on Auto-Steering.
You can lengthen the time window in order to get more acquisitions over the area. Hit the Refresh button to recalculate the result.
SaVoir will look for the best fit in every single acquisition opportunity and apply the chosen selection criteria.
