I'm exploring several methods of classifying multi spectral data in eCognition.
The classification will be fairly high level; I'm not trying to find individual species but want to identify areas of forestry, urban areas and water bodies.
Most methods require training areas, but in this instance, I need an automated method. eCognition appears to be the best solution as you can create rules based on the spectral characteristics of the land cover types but this is an expensive solution!
Has anyone used any alternative methods?
