臺北市多目標地籍圖系統可提供查尋定位功能，惟並無分析、統計等一般地理資訊系統(GIS)具有的功能，使得地籍資料無法發揮更大功效，同時筆者服務機關既有之『縣市圖根管理系統』因開發較早，受限於原開發程式限制，無法與需高記體之其他軟體相容，另一方面，民眾申請多目標地籍圖，目前仍以紙本方式供應，亦無法發揮與其他政府機關或民間開發建置之地理資訊系統(GIS)圖資整合應用之功能，若能提供符合開放地理資訊編碼標準之地籍圖資，民眾可自行加值應用，將可大幅提升政府為民服務品質。由於臺北市多目標地籍圖系統功能不足，以及既有之『縣市圖根管理系統』無法正常使用，亟需開發新系統，然而，當欲增加功能時，又常受限於原開發廠商、預算編列及招標程序，導致緩不濟急。
開放式地理資訊系統聯盟製定了開放式地理資料跨平台規格書，依此規格書開發之開放源碼軟體常具有免費、跨平台、資料模組化、資料交換方便等優點，讓使用者能免費的取得軟體；同時中央研究院亦提供了許多GIS應用軟體工具供人下載使用，因此若能藉由開放源碼軟體之輔助，將地籍圖資加值應用，提供地籍圖查詢定位、套圖展示以及產製符合開放地理資訊編碼標準之地籍圖、圖根點檔，將可提高地籍資料於GIS之應用。
本研究蒐集臺北市信義區之地籍圖、圖根點及都市計畫中心樁位坐標成果，以開放源碼GIS (Quantum GIS)進行地籍資料加值之建置及處理，建置完成後之成果，可於Quantum GIS中進行定位查詢、套圖展示等操作，並可依需求製作客製化地籍圖，產製地籍圖及圖根點成果KML檔，供民眾下載後加值應用，對提升為民服務有極大助益。 / The “Taipei City Multi-purpose Cadastral Map System” can be used to search and identify location. However, it lacks of functions provided by GIS (Geographic Information Systems) such as analysis and statistics, hence its utility is limited. Since the “Supplementary Control Point Management System for City and County Government” of the researcher's institute was developed in a very early year, due to its limitation, the software is incompatible with the other software which needs large memory. In addition, multi-purpose cadastral map is currently provided to the public in paper copy, thus it cannot be integrated with other GIS data established by government or private institutions. If the cadastral map conforms to the Open Geodata Interoperability Specification (OpenGIS), it can improve the quality of service provided by the government to the public because value-added applications can be developed. As both the aforementioned systems are not sufficient to meet the needs, there is great demand for developing a new system. However, the development of new functions or systems is often restricted by the original developer, budget, and procurement procedure, hence it is not efficient for the urgent need.
The Open Geospatial Consortium (OGC) has defined a set of open interfaces based on the OpenGIS. Most of the open source software that conforms to OpenGIS has the advantages of free of charge, cross platform, modulized data, and data interchangeability. It is free and easy for users to obtain open source software. Academia Sinica also provides several GIS application software for free download. By using open source GIS software to provide functions such as searching, identification, overlaying, and producing maps for cadastral maps and supplementary control points, it will enhance the value of cadastral map data in GIS applications.
This research collected data of the Xinyi District of Taipei City, including cadastral maps, supplementary control points, and central piles’ coordinates for urban planning. An open source GIS (Quantum GIS) was used to process cadastral maps, and the results can be used for location searching, and overlaying maps. Moreover, customized cadastral maps can be produced on demand, and the cadastral maps and supplementary control points can be converted to KML (Keyhole Markup Language) file format, which can be downloaded by the public for value-added applications. The results is expected to greatly improve services for the public.
