A system and method for processing a satellite image to determine a terrain boundary. Pixel data corresponding to a satellite image is obtained. For each pixel within a subset of the pixel data, multiple image features are determined corresponding to texture and color statistics for the pixel and neighboring pixels, based on a feature selection process for selecting discriminative features. An initial set of rules is generated for determining a terrain boundary. Plural image models for applying to the pixel data are created based on the initial set of rules. The plural image models are applied to the pixel data to generate at least one probability map, which represents output of the plural image models and corresponds to different terrains within the satellite image. A binary label mask is generated for the satellite image based on the probability map, and mask indicates segmentations corresponding to the different terrains.
