Abstract
The Automated Site Construction, Extension, Detection and
Refinement system (ASCENDER) has been developed to automatically
populate a site model with buildings extracted from multiple,
overlapping views. Version 1.0 of the system has been delivered
for evaluation on classified imagery. Evaluation results
on an unclassified Ft.Hood data set are presented here.
Extensions to the system that allow it to detect a wide range
of building classes, including peaked roof and multi-level
flat roofed structures are described. Recent work
on symbolic extraction of surface structures such as windows
greatly enhances the visual realism of graphical site model
displays.
