【摘要】：GIS服務(wù)器是網(wǎng)絡(luò)GIS的核心，它在整個(gè)系統(tǒng)中起著最終的功能輸出的作用。隨著信息技術(shù)發(fā)展和網(wǎng)絡(luò)的普及，對(duì)GIS服務(wù)器的需求有了新的變化。這些變化包括：客戶端形式的多樣化；大計(jì)算量給服務(wù)器帶來(lái)的負(fù)載壓力；海量空間數(shù)據(jù)的存儲(chǔ)和訪問(wèn)等。本文基于這些需求，對(duì)開(kāi)源版MapGuide的功能進(jìn)行了研究和擴(kuò)展。 本文介紹了MapGuide的現(xiàn)有功能和特性，并詳細(xì)研究了其源碼。MapGuide是OpenSource Geospatial Foundation的GIS服務(wù)器軟件，它功能豐富，操作簡(jiǎn)單，易于二次開(kāi)發(fā)。本文依據(jù)其源碼，對(duì)MapGuide服務(wù)器端和MapAgent進(jìn)行調(diào)試，得到了系統(tǒng)的整個(gè)執(zhí)行流程，，并總結(jié)了對(duì)其擴(kuò)展的關(guān)鍵點(diǎn)。為了適應(yīng)多客戶端，研究了Restful Web服務(wù)，并將其引入MapGuide。隨后，研究了瓦片緩存，這對(duì)減輕MapGuide服務(wù)器的負(fù)載至關(guān)重要。緩存一次生成多次使用，減少了不必要的實(shí)時(shí)繪制。本文研究了MapGuide的存儲(chǔ)組件FDO，并引入MongoDB以解決對(duì)海量空間數(shù)據(jù)的存儲(chǔ)問(wèn)題。 針對(duì)MapGuide的現(xiàn)狀和新的需求，本文實(shí)現(xiàn)了對(duì)MapGuide Restful Web服務(wù)的擴(kuò)展、對(duì)自定義緩存的支持和MongoDB Provider的核心功能，這使MapGuide更具有實(shí)用價(jià)值。
[Abstract]:GIS server is the core of network GIS, it plays the function of final function output in the whole system.With the development of information technology and the popularization of network, the demand for GIS server has been changed.These changes include: the diversification of client forms, the load pressure brought by the large amount of computing to the server, the storage and access of massive spatial data, and so on.Based on these requirements, this paper studies and extends the function of open source MapGuide.This paper introduces the existing functions and features of MapGuide, and studies in detail its source code. MapGuide is the GIS server software of OpenSource Geospatial Foundation. It has rich function, simple operation and easy to be redeveloped.According to its source code, this paper debugs the MapGuide server and MapAgent, obtains the whole execution flow of the system, and summarizes the key points of its extension.In order to adapt to multi-client, the Restful Web service is studied and introduced into MapGuide.Subsequently, the tile cache is studied, which is essential to lighten the load on the MapGuide server.The cache is generated multiple times at a time, reducing unnecessary real-time rendering.In this paper, the storage component of MapGuide is studied, and MongoDB is introduced to solve the storage problem of massive spatial data.According to the current situation and new requirements of MapGuide, this paper implements the extension of MapGuide Restful Web service, the support of custom cache and the core function of MongoDB Provider, which makes MapGuide more practical.
