| 摘 要： | 针对我国陆上油气资源分布不均、点多面广、信息量大的特点,开发了一个基于MapX的中国油气资源地理信息系统,重点对该系统中图形查询的鹰眼功能进行了研究开发。通过编程,实现了可选择性地浏览图形的局部、调整图形显示比例的功能,同时还可以显示局部图形在全图中的位置,大大提高了信息查询效率,为决策部门提供了强有力的技术平台。

| Abstract: | The geographic distribution of ashore petroleum resources in China is uneven and scattered,and the contents of information is very huge.In this paper,the Chinese oil and gas natural resources information system is introduced.The hawk-eye function of spa- tial query in this system is developed.So parts of The map can be choicely showed,the scale of the map can be adjusted on the main map area,and the location of the map showed on the main area can be indicated in the whole map,which is showed on the little zoom in the left screen.So the efficiency of spatial query processing has been largely improved. |
