應用網際網路技術改善建管套繪圖作業之研究

Abstract

本研究之目的為改善建築管理機關中，承辦建築執照申請案件之承辦員，於辦理建築套繪圖實質審查時，需要將建築套繪圖說以人工方式套疊於地籍圖上之作業。藉由規劃一套建築套繪圖之線上套繪流程，本研究得以簡化建管申請流程，並藉此提高建築管理效率；又經由空間資訊的電子化，協助建管人員透過空間資訊來整合建管資訊，使建管人員或都市計畫人員在決策分析時，除了以往只有文字資訊可供參考外，另外還可透過Google Earth的2.5D視覺化機制與地景模擬機制將建築物之2.5D空間資訊更完整地呈現。研究經由需求分析與資訊技術分析，提出一套網頁介面的建築執照之建築套繪圖網際網路管理雛形系統BGMWeb（Web-based Building Geo-parcel Management System），將目前建管系統中，以文字檔案為主的建築套繪圖管理，提升為對房屋建築套繪圖形之圖徵管理，並藉由圖徵管理將WebGIS上的建築套繪圖座標資訊後，可自動加入建案申請之樓高資訊後，可自動匯出建物2.5D模型之KML檔案，使建物2.5D模型與建管資訊能夠互相查詢與檢視，達到圖文整合之目的；再加入建築執照申請時間，便可使用GoogleEarth內建之時間軸功能，來呈現城市建物發展之歷史演進。

In this research, we develop a web-based system, named BGMWeb (Web-based Building Geo-parcel Management System), that manages 2D geometric building information on WebGIS using MapGuide OpenSource and 2.5D building models for landscape simulation on Google Earth to serve as an effective tool for administrators to store, query, and manage the geo-parcel information of buildings. By integrating the coordinate information of buildings from their corresponding geo-parcels on WebGIS and the height value from the administrative building database, BGMWeb can generate a 2.5D geometry file in the KML file format for landscape simulation on Google Earth. Through loading the queried KML (Keyhole markup language) file in Google Earth, users can also click the hyperlink of a building to query its 2D geometry and text-baed information in BGMWeb. BGMWeb takes advantage of AGF (Autodesk Geometry Format) to support modeling and storing geographic features (such as points, lines, and polygons) for display in MapGuide OpenSource, and KML to support modeling and storing geographic features (such as points, lines, images, polygons, and models) for display in Google Earth. Furthermore, by integrating the time information from the administrative building database with 2.5D models, the evolution of buildings of a city or county can be simulated in Google Earth.
