Abstract
 ArcGIS Software-Based Change Detection Analysis Extension to Manage Land Asset Changes Track: Petroleum Author(s): Khalid Al-Arfaj, Bader Al-Khlaiwi, Zhang Huaisu Detecting land use and feature changes over time is fundamental and necessary for updating GIS base maps and the management of both facilities and natural resources in Saudi Aramco huge land reservations. The extraction of feature changes was traditionally conducted by visual comparison between multi-date images, or between old maps and updated remote sensing images without reliable GIS or engineering accuracy. In an ongoing mega-project of change detection in Saudi Aramco, a new and efficient methodology is used. The system architecture makes full use of Esri ArcSDE and ArcObjects capabilities to manage large-size images and integrate compared temporal images into a color composite for change enhancement and visualization. Excluding temporal and multi-source imagery preparation and object-oriented changes' extraction aspects of the system; this paper will mainly discuss the management of large-size temporal imagery of different types in SDE, the creation of image comparison engine, query, and the accurate mapping of the changes extracted from the compared images for change detection.
