Tie Break Methods

There are times when multiple new sample locations fulfill the goal of the sample design. In this case, a decision must be made so that only one of the new sample locations is chosen. SADA has three types of tie break methods.


Random A random number generator is used to select one of the sample locations. The seed is used to feed the random number generator. Using a seed allows the user to recreate a resulting sample design by entering the same value.

Maximize spatial coverage The value that will maximize the spatial coverage of the site is chosen as the new sample.

Closest to center of site The value that is closest to the center of the site is chosen as the new sample.
