ACCURACY ASSESSMENT OF MAPPING PRODUCTS PRODUCED FROM THE STAR-3i AIRBORNE IFSAR SYSTEM

چکیده
Traditional photogrammetric mapping technologies are being challenged by the increasing demands for faster and cheaper digital mapping products. High-resolution airborne Interferometric Synthetic Aperture Radar (IFSAR) systems are starting to penetrate the traditional photogrammetric market due to their operational and economic advantages. Many geo-spatial data, such as Digital Elevation Models (DEMs), Digital Ortho Images (DOIs) and Topographic Line Maps (TLMs), can be derived efficiently and quickly by using the IFSAR system and appropriate processing technologies. These products have proven to be an important data source for Geographic Information Systems (GIS). The main objective of this paper is to examine in detail the positional accuracy and characteristics of these topographic products through a comprehensive test.
