If you want exact data values, you should set the probe sampling mode to be Nearest Neighbor instead of Weighted Average. You can change this preference globally using the Edit->Resources->User Preferences menu (under the General Tab). > We are making use of the color map which ranges from 0 to 80 dBz.I would >like to know how values greater than 80dBz or less than 0 dBz are displayed in >the Image. Any value outside the range of the color table will be displayed in the same color as the color table at that end of the range. So for example any values below zero will be displayed as black. You could create a new color table or change the range of the existing color table to display values outside the default range.
