Abstract:

In order to improve the application level of high-resolution optical remote sensing image in the field of railway survey and design, this paper systematically summarizes the current situation of high-resolution optical image and its application in geographic information products, geological survey and environmental impact assessment and so on, combined with the characteristics of current railway survey and design. The future research focus include high reliability and high precision processing technology for remote sensing image adapted to the characteristics of railway survey and design, improving the accuracy of remote sensing data interpretation, information extraction intelligence and so on. The purpose is to form an efficient application system of optical remote sensing satellites in railway survey and design.

Key words: high resolution remote sensing image, railway survey and design, geographic information product
