Example 2 with Bounds

use of au.gov.amsa.geo.model.Bounds in project risky by amsa-code.

the class DistanceTravelledCalculator method partition.

/**
 * Returns a sequence of {@link Options} that are same as the source apart
 * from the {@link Bounds} which are partitioned according to horizontal and
 * vertical parameters. For map-reduce purposes we need to be able to
 * partition the bounds of Options. Passing horizontal=1 and vertical=1 will
 * return one item only being a copy of the source {@link Options}.
 *
 * @param options
 * @param horizontal
 *            number of regions (with longitude)
 * @param vertical
 *            number of regions (with latitude)
 * @return
