野外地形匹配和重力测量自动布点系统

Design for Terrain Matching Visualization and Arranging Gravity Points of Gravity Survey System

野外重力测量是精化全球和局部重力场模型的重要手段之一。以我国1∶5万数字高程数据库为基础,结合地形景观生成技术,构建了野外地形匹配可视化及重力测量的自动布点系统。在重力测量布点方案的设计中,给于用户施测区域所属地形及布点点位以直观的认知形式。尤其对于地形较为复杂的山区、特大山区,可对外业测量点位进行优化,减少外业的工作量,提高重力测量的外业工作效率。

Field gravity survey was an important method of gravity field model optimization. At present, local gravity filed and geold were not exact enough for national defence and construction. This paper introduced the design and software construction for arranging gravity points of gravity survey and terrain matching visualization system based on the 1 ： 50 000 digital elevation database. In 3D terrain visualization environment, the system advanced work efficiency of gravity survey especially for arranging gravity points.
