摘要：Digital orthophotos are used by many professionals in land management and fields such as planners, foresters, soil scientists and zoning administrations. As the field of photogrammetry moves to the digital domain, the increasing numbers of digital photogrammetric systems (DPS) appear in the commercial market. DPS can produce digital orthophoto product with greater speed, lower cost, and an effective interface to geographic information systems (GIS). However, a significant segment of the user community is still cautious about product accuracy of these new systems. The goal of this research is to theoretically analyze the main influential factors in the planimetric accuracy of digital orthophotos according to the production process of digital orthophotos in order for us to take some measures to control the quality of them ,and enhance user's belief for them
