【摘要】：近年来,受国内外矿业和石油市场需求的拉动,航空物探工作迅速得到加强,航空地球物理勘探数据资料量大幅度增长。如何高效管理和利用这些数据资料,使其更好地服务于矿产资源的开发和利用成为了研究热点。近年来,地理信息系统技术(Geographic Information System,GIS)技术与互联网(Internet)技术相结合形成的网络地理信息系统(Web GIS)技术为数据资料共享和服务提供了新的方法和技术,逐渐成为了可提供快速稳定的数据资料服务的主要途径。本论文的目标为分析航空物探数据库的特点,设计并实现航空物探信息服务软件。在应用中发现,服务系统涉及到海量航空物探数据资料的在线服务,这会导致响应速度慢、人机交互能力差等一系列问题。为解决上述问题,在系统设计中分别利用瓦片金字塔技术和矢量优化技术对基础地理数据和航空物探矢量数据进行了地图发布前的处理。再结合业务逻辑,采用Arc GIS Server技术进行了服务端程序的设计和开发;客户端以插件形式集成于Geo Probe地球物理软件平台,实现航空物探数据处理、服务管理一体化,大大提高物探工作人员的工作效率。总结本次毕业设计的主要研究内容如下:(1)航空物探数据特点研究与分析;(2)结合基础地理数据的特点,提出瓦片金字塔技术,并编程实现了相应的系统功能模块;(3)结合航迹线数据特点,提出数据抽稀技术,并发布优化后的航迹线数据服务;(4)利用Web GIS Services技术进行了航空物探数据服务软件的设计和开发,基于Geo Probe平台,实现了数据浏览、查询等功能,并进行了应用示范。
[Abstract]:In recent years, driven by the demand of domestic and foreign mining and oil market, the work of aerogeophysical exploration has been strengthened rapidly, and the amount of data of aeronautical geophysical exploration has increased greatly. How to manage and utilize these data efficiently. In recent years, Geographic Information system (GIS) technology has become the focus of research on the development and utilization of mineral resources. Web GIS (Web GIS) technology, which combines GIS technology with Internet technology, provides a new method and technology for data sharing and service. The aim of this paper is to analyze the characteristics of aeronautical geophysical exploration database and to design and implement the aerogeophysical information service software. The service system involves the online service of massive aeronautical geophysical data, which will lead to a series of problems, such as slow response speed, poor human-computer interaction ability and so on. In the system design, the basic geographic data and aeronautical geophysical vector data are processed by using tile pyramid technology and vector optimization technology, respectively, and combined with business logic. Using Arc GIS Server technology to design and develop the server-side program; The client is integrated into Geo Probe geophysical software platform in the form of plug-in to realize the integration of aeronautical geophysical data processing and service management. The main research contents of this graduation project are summarized as follows: (1) study and analysis of aeronautical geophysical data; (2) based on the characteristics of basic geographic data, the technology of tile pyramid is put forward, and the corresponding system function module is realized by programming. (3) combining the characteristics of track data, the paper puts forward the technology of data thinning, and publishes the optimized track data service. 4) Design and development of aeronautical geophysical data service software based on Web GIS Services technology, and realize data browsing based on Geo Probe platform. Query and other functions, and the application of demonstration.
