The Research Of Supervising The Violating Construction Land From Remote Sensing Image

Urban planning is based on the city economical and social developing aim in a specific period. Its tasks include establishing the city character, size and development orientation and planning urban land use, coordinating urban space functional distribution, arranging all sorts of construction works comprehensively. It is the essential way to reach the goal of city economical and social development. Governmental officials enact regulations mainly according to urban planning in protecting ecological and natural environment, using resources reasonably, arranging city developing distribution and maintaining the harmony of city development. Urban planning can fulfill the comprehensive, harmony, sustainable city development through disposing the relationships such as composition and division, long-term and short-term, reality and possibility, economical development and social development, urban construction and energy saving, urbanization and legacy protection. It is character in comprehensive, pragmatic.The pace of urbanization accelerates in recent years and the role of urban planning becomes more and more important. On the contrary, many violating construction land emerges by the incentive of economical benefits. Supervising the implement of urban planning is an important work of urban planning administration department. It contains the supervision of unauthorized construction projects, inspection of the implement conditions of authorized projects, and other violating projects. As the officers of planning administration, they need to find these illegal actions and take actions immediately.Nowadays the method of urban planning changes from qualitative ways to the combination of qualitative and quantitative ways but the primary problem is the acquisition of fundamental data. The formal approaches in acquiring and analyzing data is an energy-spending and low effective way while the remote sensing technology can provide more new information especially the high resolution images such as IKONOS, QUICKBIRD etc..The high resolution image is one kind of very good data pool for supervising the urban planning construction land changes. Uses the remote sensing images of different time, through the method of the automatic classification discovery and the man-machine interaction interpretation, obtains the region information of the construction land, then using the GIS spatial analysis method to get the urban construction land change information, and compare the plan examination case, realizes to the supervising of the violating construction land.This paper carries on the violating construction supervising experiment in the research remote sensing imagery processing's foundation through the same site and different phase's high resolution IKONOS remote sensing image, obtains the violating land information finally, it has the very good feasibility and the validity. The direct profit is: Raised the identification efficiency of the urban planning remote sensing supervising topic target; Enhances the legal solemnity of the special goal supervising result; Reduction the artificial labor intensity, reduction investigation violating goal's time largely, raises the working efficiency.
