The Interactive Supervised Classification tool accelerates the maximum likelihood classification process. It works the same as the Maximum Likelihood Classification tool with default parameters. All the bands from the selected image layer are used by this tool in the classification. The classified image is added to ArcMap as a raster layer.
To gain an optimal interactive experience, the input image should have pyramids built. When pyramids are present for the input image, the interactive supervised classification uses the resolution associated with the current pyramid level in the display. Also, zooming into a small extent of the image will make the classification faster because the tool only processes the pixels in the current display extent.
- No signature file is needed for this tool to run. Once you've created a few training samples, just click this tool to perform the classification.
- The input image should have pyramids built to gain a better interactive experience.
- You can use this tool as an exploratory tool in creating the training samples. It allows you to quickly preview the classification result for a given training sample set.
