I'm working with Landsat images and I would like run Sobel convolution kernel filter to find out borders of forests. But I don't have any experiences, maybe is simple and ArcGIS has some extension for this kind of operation or is some better way to find out borders (edges) of forests? Please help me.

Best regards
