全国航放数据库的建设

Establishing of China Airborne Radiometric Database

全国航放数据库系统成功地解决了不同类型航放测量数据源的录入、重复数据检索等关键技术问题并已录入 3 0多个测区的航放 (部分含航磁 )数据 ;研究、应用概率论数理统计学原理 ,解决连片 (重复 )数据的标准化方法与实现 ;完成了检索的库原始数据、查询计算的标准化数据或比值计算数据等直接网格化的程序设计 ;探索了图形数据与标量数据库的接口技术 ,开发了屏幕绘图及与相关软件接口程序 ,做到了文图并茂。使全国航放数据库具有 :灵活、可靠的数据录入 /导入功能 ,方便、可视性强的查询 (统计 )功能 ,实用、快捷的数据处理应用功能 ,适时、完备的输出功能 ,易用、可扩展的系统维护功能 ,严密。

The China Airborne Radiometric Database system has successfully solved a series of problems,such as the input and index of different types airborne radiometric survey data resources (more than 30 survey area data have been input);by applying the principle of the theory of probability and mathematic statistics mutually linked (repeated) data have been normalized,the program of the transformation of data into index,as well as the program for the gridization of normalized data or ratio data have been completed;the interface techniques for connecting figure data and database have been discussed,and the interface program for screen mapping and relevant softwares have been developed.The newly established airborne radiometric database is characterized by:high flexibility,reliable function for data input and import,high convenience,and strong visual querying (statistic) function,practical and fast data processing function,suitable and perfect output function,easily operatable and extensible system maintaining function,and tight and secure data preserving function.
