Design-specific Parameters
When Hot Spot: Calculate Probability is selected during the Set sampling parameters step, the Parameters Window changes to look like the following:
Under Grid Definition, select a square, triangle, or rectangle grid style and enter the Length of X side.
Enter the parameters for Shape Definition. For Hot Spot Shape, enter a value that is greater than or equal to .2 and less than or equal to 1. This is the ratio between the major and minor axes of the elliptical hot spot. (Note that 1 is a circle.) For Hot Spot Orientation, select Random to use omni directional ellipses, or select Degrees and enter a value between 0 and 90.
Define the Hot Spot Definition by setting either the area or the length of the semi-major axis (note that the other value will change accordingly).
Press Show the Results. SADA will present a message re the number of new samples and their probability of hitting a hot spot before displaying the new sample locations in the Graphics Window. If there are polygons, new samples will only be placed inside the active polygons.
To view the actual coordinates of the new sample points export the information to a comma delimited excel file by using the Output to File toolbar button in main form of SADA.
