Abstract

The invention discloses a three-dimensional map scene building method based on various data. The method comprises the steps that a geographic area range is set according to scene building requirements; the method comprises the following steps: acquiring an electronic chart of a geographic area range, acquiring a water depth characteristic element value for the electronic chart, and generating a vector point element file based on the water depth characteristic element value; acquiring a digital elevation model of a geographic area range, processing the digital elevation model, and generating a vector point element file based on an elevation value; adjusting the coordinate system of the generated vector point element file, combining to generate a new vector point element file, and generating a combined digital elevation model; and establishing a three-dimensional scene and/or three-dimensional terrain model according to the combined digital elevation model. According to the invention, a sea-land integrated three-dimensional effect is rapidly realized, and meanwhile, rendering effects in different water depth ranges are realized according to water depth values; the three-dimensional scene simulation module is placed in a map application engine to achieve three-dimensional scene simulation tending to a real terrain; and meanwhile, a three-dimensional terrain model based on real landform features is generated.

Description

technical field [0001] The invention relates to a method for building a three-dimensional map scene, in particular to a method for building a three-dimensional map scene based on various data. Background technique [0002] With the growth of the shipping industry and related industries and the development trend of the map industry, future maps will develop vigorously from two-dimensional planes to three-dimensional three-dimensional trends, and there will be more and more map-using industries including the shipping industry and related industries. Use a 3D map as a reference. However, the traditional two-dimensional map, due to its planar feature, can only mark the data in a limited two-dimensional plane but cannot visualize the data, and cannot provide users with a better simulation experience based on real scenes . [0003] The 3D map can add a three-dimensional effect on the basis of the 2D map. Most of the existing 3D elevation data models (DEM) only include ground ele...
