Abstract: This paper describes an object-based methodology devised to enable accurate and detailed habitat mapping using IKONOS VHR satellite images. The Multi-scale Object Oriented Segmentation with Decision Tree Classification (MOOSC) comprises a suite of image processing techniques applied interactively by the user in response to study area characteristics, and data dimensionality. Because of the inherent flexibility of the method, MOOSC can obtain high mapping accuracy even in the rugged terrain of the present study area combined with the low solar zenith angle of the wintertime images used. The accuracy of 90% obtained for MOOSC increases to 94% if habitat classes are based purely on physical structure rather than life form, ie. if shrub-sized tree seedlings planted on grassy slopes are classified as shrubby grassland, which they resemble physically and spectrally, although logically they belong to the forest class. Thus the MOOSC method is able to achieve similar accuracy to stereo air photo interpretation from large scale, high quality colour photos (which achieved 95% accuracy), but at only one third of the cost.
