Abstract

With the progress of researches on the integration of Geographic Information System (GIS) and Remote Sensing (RS), digital earth, and information sharing, to publish RS images on the Internet has become a significant research work. In this study, image pyramid model was introduced, and an efficient algorithm to build image pyramid was presented for convenient data storage and retrieval. In order to improve the efficiency, the process of image cutting and resampling was implemented in the RAM, avoiding the unnecessary I/O operations. The algorithm was implemented by combining Java and C++ languages, ensuring both the processing speed and distributed architecture. And two distributed implementation approaches were proposed, based on B/S and C/S architecture respectively. In the programs, some useful functions, such as data compression, image format conversion, watermarking, and automatic error-correction, were also implemented to facilitate and ensure the web publishing work. Tests of the programs with a global RS image showed that they worked efficiently, robustly, and flexibly under the Internet environment. Also, the programs were endowed with user-friendly graphical interfaces, and easy to use. Therefore the rapid web publication of RS images on the Internet becomes easier to accomplish.
