AN OPERATIONAL MULTI-SENSOR GEOCODED PRODUCTION SYSTEM FOR EARTH RESOURCES SATELLITE IMAGES

It is highly demanded to integrate the remote sensi ng images with other spatial data in geographic inform ation systems, hence, an efficient and reliable geocoded production system is a must for a ground receiving station or a data provider of remote sensing satellite imag ery. From the operation's point of view, most of the com mercial packages are not quite suitable for our specific ne ed in massive production, simply because their structure is dedicated to individual application. The objective of this paper is thus to design an, indigenous, workorder-b ased multi-sensor geocoded production system in a PC-Int ernet environment, called the MSGPS system. The features of the proposed system include (1) automatic workflow control, (2) low cost of hardware and maintenance, (3) high production throughput, and (4) possible multi-senso r expansion. The major functions of the proposed syst em are (1) web querying and ordering, (2) workorder management, (3) orbit modeling and quality control, and (4) ortho-rectification kernel. Preliminary test result s indicate that the proposed system can reach high performance and geometric quality with low cost.
