| Three options are provided for defining contour intervals in the Contour Options dialog. The options are as follows:
| | #REDIRECT [[WMS:Contour Options]] |
| | |
| ===Number of Contours===
| |
| With the Number of Contours option, an integer is entered representing the total number of contours. The contour interval is adjusted based on the current active data set so that the contours are evenly spaced and the number of contours correspond exactly to the specified value.
| |
| | |
| ===Specified Interval===
| |
| With the Specified Interval option, the contour interval (5, 10, 20, etc.) is entered directly by the user.
| |
| | |
| ===Specified Values===
| |
| The Specified Values option allows the user to enter a list specific contour values. Contours are only generated at these values.
| |
| | |
| If the Log Scale option is selected, WMS automatically assigns contour intervals as multiples of 10. Furthermore, if the color-fill or color ramp option is being used, the colors assigned to the contours are distributed in a logarithmic fashion, rather than linearly interpolated from the low to high values.
