Research on the Establishment Method of Plane Coordinate System of Highway Engineering under Complex Terrain Condition
In order to meet the needs of the survey and design of highway engineering and later on-site construction, it is very necessa-ry and important to establish a suitable plane coordinate system. Based on the two main influencing factors of Gaussian projection de-formation and the feature that the sum of them can be partially offset, the establishment process of the plane coordinate system of high-way engineering under complex terrain conditions is analyzed with an example. Concurrently, in order to overcome the limitations of the average representation of the whole and the deformation inspection method of "representing the surface by points" in the establish-ment process of the conventional method, the method of applying DEM to inspect the projection deformation is studied, which can real-ize the statistical analysis and visual display of the projection deformation within the whole survey area, and provide a reference for the establishment of the highway engineering plane coordinate system under complex terrain conditions. The example shows that the meth-od is applicable and effective under complex terrain conditions, and has certain theoretical and practical significance.
