Contour Extraction
The raster processing extension comes with a contour extraction utility that's both powerful and fast.
A contour is a line that connects places with the same sample value. This utility finds contours in raster images. Contours can be generated on any image that can be opened by Orbit GIS.
| Image | The image and band to operate on. This must be an opened dataset. |
|---|---|
| Reference | The reference value to start making contours from. |
| Include Reference Value | Treat a sample that equals the reference sample value as inside the contour? |
| Interval | The interval between contours. |
| Interpolation | The interpolation technique to utilize. See below for more information. |
| Progress | Progress indicator of the generator task. |
