摘要
A computer implemented system and method are disclosed for segmenting aerial and satellite imagery according to pre-defined regions contained in the images such as city blocks. An example system comprises a feature mask generation module, a partition generation module, one or more color map generation modules, a color map reassignment module, and a bounding box generation module. The system and method take aerial image data and vector map data as input and generate a composite color map for a geographic region of interest, wherein the color map comprises a plurality of pre-defined regions in which each pre-defined region can be defined by enclosing road segments. The disclosed system and method provide a convenient and logical way of segmenting large data sets of aerial imagery for use in other applications such as the construction of computer models of surface features of the Earth.
