The method of making the airborne geophysical thematic base-map based on spatial analysis: Exemplified by the Dazhou-Huaying survey area
-
摘要: 地理底图是航空物探专题图的重要基础环节及组成部分,但以往人工手动抽稀处理方法较为繁琐。本文对航空物探专题底图的作用和现状问题进行分析, 引入空间分析方法,借助1:25万公众版地形数据库进行规划底图编制实践,完成地理要素矢量化。以四川省达州—华蓥测区为例进行测试,证实该方法制作的地理底图简便实用,相比以往处理方法,更加智能化,且制作成果快速准确,符合相关精度要求;此方法为航空物探专题图的精准制作提供了有力支撑,方便用户使用,同时也为航空物探的发展奠定了一定基础。Abstract: Geographical base map is an important basic step and component of airborne geophysical thematic map; nevertheless, the previous treatment methods seem to be rather complicated. This paper analyzes the function and present situation of the thematic base map of aero geophysical exploration and introduces the spatial analysis method. With 1:250 000 public versions of terrain data, this paper discusses the idea and method of compiling the thematic base map of aerial geophysical exploration, and completes the vectorization of geographical elements. The Dazhou-Huaying survey area in Sichuan Province is chosen to perform test. It is shown that the basemap designed by this method is simple and practical and, compared with previous processing methods, it is more intelligent, and that the production results are fast and accurate and can meet the relevant precision requirements. This method provides a strong support for the accurate production of airborne geophysical thematic maps, and it is easy to use. At the same time, it also lays a foundation for the development of airborne geophysical exploration.
