3 3D high precision digital mapping system

摘要

The present invention relates to a three-dimensional high-precision digital map production system, and more specifically, a ground object image represented by a polygon object type in a digital map is precisely compared with the actual topographic image located at the corresponding point to identify the inconsistent point and the corresponding point. Improved three-dimensional high-precision digital maps to efficiently and indirectly cool the enclosures in which the modules are mounted so that the numerical coordinates of the module can be adjusted or the ground water image can be adjusted to the position of the numerical coordinates while suppressing the deterioration of the modules required for digital map processing. It's about the system.
