Application and Prospect of Spatial Information Technology in Inland Waterway Resources Census

Abstract

AbstractIn recent years, the rapid development of GIS, remote sensing, big data and other spatial information technologies have provided a huge driving force for the information construction and development of many industries. As an important branch of transportation field, inland water transportation also has great development opportunities in information construction. Since the second National Inland Waterway Census, great changes have taken place in the current situation of China’s inland waterway. It is urgent to carry out a new round of National Inland Waterway Census and comprehensively find out the current situation of China’s inland waterway. This paper comprehensively discusses the current situation of the application of spatial information technology in the general census of resources in typical industries. This paper also summarizes the basic situation of Inland Waterway Census in China, and analyzes the key and difficult points of the application of spatial information technology in Waterway Census data acquisition, working base map compilation, application achievement display and so on. It initially puts forward the technical scheme of channel resources census based on information means and online system. Compared with the traditional offline census, the technical scheme proposed in this study has achieved a breakthrough in improving the efficiency of census and ensuring the quality of census results. The research can provide technical reserves and experience for the general survey of channel resources for the whole country and all the provinces.
