set by specifying the rectangular area of the grid that you are interested in<br />

andbyspecifyingtheselectionMode.<br />

You define the rectangular area by specifying two points that specify two<br />

corners of the box:<br />

• Corner 1 — Specify longitude and latitude values in decimal degrees.<br />

Typically, Corner 1 is the upper-left corner of the box.<br />

• Corner 2 — Specify longitude and latitude values in decimal degrees.<br />

Typically, Corner 2 is the lower-right corner of the box.<br />

You specify the selection mode by choosing the type of Cross Track Inclusion<br />

and the Geolocation mode. TheCross Track Inclusion value determines<br />

how much of the area of the geographic box that you define must fall within<br />

the boundaries of the swath.<br />

Select from these values:<br />

• AnyPoint — Any part of the box overlaps with the swath.<br />

• Midpoint — At least half of the box overlaps with the swath.<br />
