Appliance of the Digital Orthophoto Map (DOM) Technology in Urban Land Management

Abstract

this paper firstly discussed what kind of special features the application of photogrammetry technology in urban land management need to face. And then, analyzed that the development of the modern digital photogrammetry technology provide the possibility the DOM technology applied in the management of urban land effectively. The effective Application of DOM technology, can be achieved in urban land management information system by several aspects of technology steps and a series of technical processing, such as collecting data, correcting image, synthesizing information, etc Keywords-component; Appliance; Orthophoto; DOM; land management; I. THE SPECIAL NEEDS TO IDENTIFY IN URBAN LAND MANAGEMENTWith the rapid development of computer and communication technology, human society has entered the digital information era. Digital geographic information has become the essential support conditions in urban planning, macro decision-making, and land management. In urban land management geographic information system, not only vector data, grid data, but also high-quality and visual image data and information is an essential component. As an man-made living environment, different from other types of space or area, the urban land management information has its own special needs to identify, mainly in: A. Identification of land diversification propertyTo definite relationship of urban land ownership clearly, is an important part in urban land administration. In general, the attributes of urban land property rights have wide range of types. On the owner of the land concerned, there division between public land-used and private land-used; on the land users concerned, including residential land, industrial production sites, and so on; on the use of land features concerned, including administrative office functions, business services, warehousing function, the function of transport, leisure function, and so on. All these types of division require that we understand and master land ownership properties more accurately in urban land management. In particular, we should identify the attributes and details of diversity characteristics accurately the type in urban land management. B. Recognition of the diversification of artificial environmentDifferent from the general sense of the natural environment, city is not only a product of social practice, but also living environment of city life. The city is bound to meet the increasingly complex needs of living, work, leisure and travel. In the modern urban land and space aggregated together with a large number of buildings and facilities. Including, all type of buildings, roads, bridges, tunnels, ports, and towers, etc. These are the achievement of development of human civilization, are important components in modern city at the same time. In the artificial environment, the state of construction, decided the functioning of land-use. The identification and recognition of these construction facilities, therefore, becomes an important technological base in the process of modern urban land mana...
