Intervals
When you select User Defined polygonisation method, a polygon is created around the breaks or intervals that you define. This method works on continuous raster only. The Interval List appears where you can preview polygon intervals and modify their settings.
- Minimum - In the Minimum field, enter the minimum cell value. The value below the specified minimum value will not be considered for polygonisation.
- Maximum - In the Maximum field, enter the maximum cell value, the cell values above the specified maximum value will not be considered for polygonisation.
- Interval Method - Depending on the method selected, fixed or custom, the items in the drop-down list change.
- Number - Specify the desired number in the Number field, if Number of intervals is selected. For example, if the input raster contains cell values between 1 to 100, and the number of intervals is specified as 5, it will result in 5 intervals with a spacing of 20 each.
- Spacing - Specify the desired number in the Spacing field, if Fixed spacing is selected. For example, if the input raster contains cell values between 1 to 100, an spacing of 20 will result in 5 intervals.
Output File
