建蔽率、容積率為都市規劃及控制都市成長所必需之土地利用強度資訊，對這些資訊的狀況瞭解程度會影響整個都市規劃政策的好壞。而現行調查方式為人工現地調查，常需花費大量的人力與時間。實際上，數值航空攝影測量與地理資訊系統等技術的進步，已可應用於輔助建立這些方面的資訊。
本研究目的在結合數值航攝影像與地理資訊系統之技術，以應用於探求土地利用強度之相關資訊。研究主要從數值航攝影像中萃取三維空間資訊，利用地理資訊系統轉換成建蔽率及容積率等土地利用強度資訊。此外，為瞭解成果之精度，本研究亦曾以地面實際測量驗證數值航測成果，結果顯示，利用單像個別量測並利用前方交會計算高程之方式，已可達到精度之要求。除此之外，轉換後之建蔽率、容積率亦較建築物原計畫之建蔽率、容積率數據大約1.1∼1.2倍。研究顯示，在進行現地調查建蔽率、容積率之前，這種方式可為快速輔助判斷之良好工具。 / It needs the information of land use intensity to control the growth of cities, such as building coverage ratio and building bulk ratio. It spends much manpower and time to get the information. The improving technology of digital photogrammetry and geographic information systems can assist investigate and collect the information.
The objective of this research has been to analyze the land use intensity with assistance of geographic information systems and digital photogrammetry. Digital aerial photographs have been used to collect 3-D spatial information of research area. This information has been imported into a geographic information system. Building coverage ratio and building bulk ratio of whole research area could be established thereafter. The information collected by digital photogrammetry has also been investigated and checked in situ.
The results have indicated that:
1. The ratios of both building coverage ratio and building bulk ratio to the original planned record have been of 1.1~1.2.
2. The most suitable height of each floor is 3.3m when calculating the floor number of building in the research area.
3. Digital aerial photographs could be very useful when the information of land use intensity was required.
