Abstract

Computer technology has drastically revolutionizing mapping disciplines. The availability of powerful database engine supported by geographic information packages has attracted many mapping agencies to improve the capability and versatility of their topographic database. A quality digital Topographic Database (TDB) is indispensable for geographic information users and economic development projects. The input data quality and database structure are crucial in the development of a versatile topographic database. In this study, the prototype of topographic database for the Sultanate of Oman is designed and developed. ArcGIS Software package has been used in this study for the database development. Topographic Database was designed in three main phases, conceptual, logical and physical models. The integration between TDB contents show a compatibility with geo-referencing image and data quality after a ground truth adjustment. The suitability of vertical and horizontal components of Shuttle Radar Topographic Mission (SRTM) elevation data and Indian Remote Sensing (IRS) 5m imagery have been analysed in this study. The assessments are made for the development of topographic database at 1:50,000 map-scales. Analyses show that the SRTM and IRC medium resolution image can be used as an alternative source of large scale topographic map production. Assessments of TDB indicate that the spatialattribute relationships are of good quality and can be a model for nationwide topographic database development for the Sultanate of Oman
