dc.description.abstractThis dissertation deals with the development and implementation aspects of a semi-automated shack reconstruction strategy for informal settlement GIS (ISGIS) data collection. The main features of this stratedy include: (1) the use of color orthoimagery and digital surface model (DSM) generated from high-resoltion small-format digitial aerial imagery, (2) the separation of the shack reconstruction task into automated shack detection and interactive shack delineation, (3) the integration of multiple cues in a desktop GIS environment, and (4) the 2.5D shack modeling and the three-dimensional (3D) realistic visualization. In accordance with this strategy an informal settlement modeling system (IS-Modeler) prototype has been developed. IS-Modeler is comprised of three software components: digital photogrammetry, image analysis and GIS. The former two are used to generate multiple cues, primarily DSM blobs, shadows and attributed edge contours, the latter is used to implement shack detection, delineation and visualization.en_ZA
