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.
