    Abstract: 大比例尺(千分之一)基本地形圖是國內最重要的基本圖資之一,也廣泛應用於不同領域。目前大比例尺地形圖仍為二維圖資,雖然有精確的二維坐標,但缺乏精確完整的三維資訊。空間資訊的應用由傳統二維平面逐漸往三維模型、室內外整合及多時序發展,並且與物聯網等新興技術結合,以達到智慧城市發展與應用。內政部自95年起陸續推動三維數位城市模型發展相關研究,對於三維房屋與道路模型建置、技術規劃與發展、模型更新、不同等級模型整合等已累積相當程度成果。隨著智慧城市的議題逐漸受到重視,如何擴充及立體化現有大比例尺基本地形圖,成為三維立體數值基本地形圖,作為新一代空間資訊基礎圖資,以滿足日趨複雜的智慧城市相關應用需求已成為刻不容緩的重要課題。 本計畫目的為分析、精進三維地形圖資技術發展與應用需求,並研發三維地形基礎圖資測製技術,以及整合三維地形圖資與物聯網並進行應用服務試辦,以期推廣、加值三維地形圖資成果。在技術發展與應用方面,本計畫工作包含:(1) 提出以三維三角網模型及三維實體模型(3D Solid Model)建置三維地形圖資核心類別模型建置之技術,並分析前2項模型優缺點、適用範疇與發展潛力;(2) 提出精進三維地形圖資測製技術自動化程度或品質方案;(3) 由航空攝影俯視角度取得空間資料延續至由地面視角取得街景之影像資料及點雲資料,進而增加三維地形圖資核心類別模型之尺度資訊與建置效能;(4) 發展三維室內外模型與物聯網標準之整合平台與試辦。 在推動與評估方面,本計畫工作包含:(1)蒐集國內外三維地形圖資測製及其測製成果物件化、三維空間資料結構與編碼及三維地形資料庫等研究、技術文件及各國發展與應用情形並提出分析;(2) 依試辦結果研擬三維地形圖測製及檢核作業技術文件指引;(3) 於期末報告提出三維地形圖資之「測製成果物件化、三維空間資料結構與編碼之策略與建議」與「測製技術之成本分析、應用領域及成果效益」;(4) 探討三維地形圖資測製中遭遇之困難或三維地形圖資技術發展需克服之問題並提出可能之解決方案;(5) 了解物聯網標準之開發與介接技術;(6) 配合內政部辦理106年度行政院災害防救應用科技方案(第2期),協助災後快速製圖技術研發相關作業。透過本計畫的執行,不僅可以整合與強化國內三維地形圖資技術發展,落實科技紮根,對於三維地形圖資應用的推廣和人才培育等也有正面貢獻,進而提昇相關產業與國家整體的競爭力。 ;Large-scale (1/1000) topographic map is one of the important geo-spatial data in Taiwan and it has been extensively applied to different domains. However, traditional 2D topographic map only provides planar coordinates and limited information about height, e.g. the number of building floors. In order to develop the necessary infra-structure in geoinformatics for smart city applications, the Ministry of Interior has been promoting 3D cyber city and related studies since 2006, including 3D building modeling, 3D road modeling, 3D model updating, technical planning and multi-scale model integration. Therefore, it has a great potential to extend the existing 2D topographic map and city models to 3D topographic map. The core objectives of this project include: (1) analysis of the demand of 3D topographic maps; (2) development of the 3D mapping techniques; (3) value-added applications using developed 3D topographic maps. The major works in technical developments and applications are: (1) developing and comparing 3D mesh- and solid-based topographic mapping methods for the critical targets; (2) improving degree of automation or efficiency for 3D digital topographic mapping; (3) increasing multi-scale information and performance for the critical targets using aerial and terrestrial remote sensing data; (4) developing and applying the platform of integrating 3D in- and out-door building models with Internet of Things (IoT). The major works in promotions and validations are: (1) collecting and analyzing the related literatures, (2) proposing the procedure and guideline, (3) proposing the strategies and cost analysis, (4) highlight the challenges and potential solutions for 3D topographic mapping; (5) realizing the IoT standards and interconnection technologies; (6) supporting the disaster-related projects.
