【摘要】：隨著移動定位技術、地理信息系統(tǒng)、無線通訊網(wǎng)絡、互聯(lián)網(wǎng)技術的迅猛發(fā)展，基于位置的服務（Location Based Services，LBS）的應用也隨著迅速發(fā)展。位置服務是根據(jù)用戶所在位置提供的一種增值業(yè)務服務，主要通過移動定位技術獲取用戶的所在位置，在電子地圖和業(yè)務平臺的支持下，為用戶提供與位置相關的信息服務。 位置服務產(chǎn)業(yè)的核心是地理空間數(shù)據(jù)的生產(chǎn)和使用。與位置服務相關的空間數(shù)據(jù)的生產(chǎn)往往需要耗費大量的人力、物力和財力，同時這些空間數(shù)據(jù)質(zhì)量的好壞直接決定了企業(yè)的競爭力。因此，如果能夠綜合利用已有的多種格式和來源的空間數(shù)據(jù)信息資源和服務資源，使其能夠優(yōu)勢互補，那么位置服務相關地理數(shù)據(jù)的生產(chǎn)成本可以大幅降低，服務質(zhì)量也能獲得提高。本文對位置服務中多源空間信息應用集成的方法進行探討，主要內(nèi)容和成果概括如下： （1）首先分析了位置服務中多源空間信息應用集成的必要性，闡述了國內(nèi)外位置服務地理數(shù)據(jù)的發(fā)展現(xiàn)狀，以及位置服務的現(xiàn)狀、形式、應用領域、特點和目前主要存在的問題。 （2）論述了多源空間數(shù)據(jù)的三種集成框架，并闡述了多源數(shù)據(jù)集成的空間基準統(tǒng)一問題，包括坐標系統(tǒng)、高程基準的統(tǒng)一、投影變換。同時，，分析了面向?qū)ο蟮臄?shù)據(jù)模型的特點和要素。 （3）以位置服務的用戶行為情境模式建模方式為依據(jù)，根據(jù)對用戶行為情境模式的分析，選擇用戶所關注的主要空間信息進行集成，從而避免信息的冗余加重網(wǎng)絡和終端的負擔，提出了多源空間信息集成的方法。 （4）基于開源GIS中間件的開發(fā)方式，采用OGC空間數(shù)據(jù)模型，利用Java語言開發(fā)了多源空間數(shù)據(jù)集成系統(tǒng)。該系統(tǒng)支持多源數(shù)據(jù)的訪問、顯示、符號化以及OGC服務發(fā)布，通過該系統(tǒng)可以方便地制作適用于基于位置的服務所需的專題地圖。最后給出本系統(tǒng)的實際案例，驗證了本系統(tǒng)可以為位置服務相關問題提供數(shù)據(jù)支持。
[Abstract]:With the rapid development of mobile location technology, geographic information system (GIS), wireless communication network and Internet technology, location Based Services is based on location. The application of LBS) also develops rapidly. Location service is a kind of value-added service service which is provided according to the location of the user. It mainly obtains the location of the user by mobile location technology. With the support of electronic map and business platform, users are provided with location-related information services. The core of location service industry is the production and use of geospatial data, and the production of spatial data related to location services often requires a lot of manpower, material and financial resources. At the same time, the quality of these spatial data directly determines the competitiveness of enterprises. Therefore, if we can make comprehensive use of existing spatial data information resources and service resources of various formats and sources, so that they can complement each other. Then the production cost of geographical data related to location services can be greatly reduced and the quality of service can be improved. This paper discusses the method of multi-source spatial information application integration in location services. The main elements and outcomes are summarized as follows: Firstly, the necessity of multi-source spatial information application integration in location service is analyzed, and the development status of geographical data of location service at home and abroad, as well as the status quo, form and application field of location service are expounded. Characteristics and current main problems. This paper discusses three kinds of integration frameworks of multi-source spatial data, and expounds the spatial datum unification of multi-source data integration, including coordinate system, elevation datum unification, projection transformation. The characteristics and elements of the object-oriented data model are analyzed. Based on the modeling of user behavior situation pattern of location service, according to the analysis of user behavior situation pattern, the main spatial information concerned by users is selected for integration. In order to avoid the redundancy of information to increase the burden of network and terminal, the method of multi-source spatial information integration is proposed. Based on the development of open source GIS middleware, a multi-source spatial data integration system is developed by using OGC spatial data model and Java language. The system supports the access and display of multi-source data. With the help of symbolization and OGC service publishing, we can easily make the thematic map which is suitable for location-based service. Finally, the actual case of this system is given. It is verified that the system can provide data support for location service related problems.
