GIS-based study on the Bohai Strait cross-sea channel route scheme

The Bohai Strait cross-sea channel, an undersea tunnel, is proposed to connect Dalian, Liaoning province and Penglai, Shandong province. The construction of the Bohai Strait cross-sea channel project can restrict the important project of national development from a certain angle, and it is helpful to promote the economic integration development of Circum-Bohai region, which has a certain importance and necessity. In order to explore the route choice of the Bohai Strait cross-sea channel, based on the theory of basic geographic information system, this paper gets data from the computer network information center China International Academy of scientific data and to obtain the contour map of the mirror site construction projects within the region by using Arc GIS software applications. According to the importance of the influence of the Bohai Strait cross-sea channel route to society and country, to explore the concrete scheme of the Bohai Strait cross-sea channel of line selection, the contour map is imported into the Auto CAD software and the specific scheme is designed. In this paper, four different route schemes are proposed, which provide a reference for the construction of the Bohai Strait cross-sea channel project. Meanwhile, this paper also compares the selection of other experts for the comparison of multiple schemes, which is based on the length of the route and the number of islands. It can provide reference for the construction of the Bohai Strait cross-sea channel.
