Create a Ranking Map

Ranking maps are used to compare two or more similarity maps according to their cross correlation values. On each trace, the map with the largest correlation coefficient is selected. The final result is capable of highlighting such characteristics as facies and thickness distributions. Follow these steps:

Use the drop-down lists to select two or more similarity maps to compare.
To change the color for each map, double-click on the color tab next to each map and select a new color.
Specify a threshold amplitude value below which no rank will be assigned.

A threshold value of 0 = all values will be output. A value of 0.9 means that only amplitude values between 0.9 and 1 will be output. All remaining values below the threshold will = No pick

If you want WinPICS to consider negative and positive values equal, select the Use Absolute Values box.
Click <OK> to create the ranking map.

The ranking map will display which map has the largest cross correlation coefficient on each seismic trace or grid node.
