Abstract

The invention discloses a method for rapidly acquiring abnormal land, which comprises the following steps of: (1) importing an image; (2) performing registration and fusion/orthorectification on the image; (3) selecting a change detection method; (4) extracting change polygons of newly increased construction land; and (5) extracting the abnormal land. A geographic information platform serves as a basis, a 3S technology serves as a core, a remote sensing image analysis and information extraction algorithm is combined, so that comparative analysis between multi-time-phase remote sensing image data and among the remote sensing image data, urban planning and planning approval results is realized, and conditions which do not accord with the planning in urban construction are timely mastered. Therefore, the urban planning monitoring and urban management are served through measures of checking, reporting, statistic analysis and the like.

Description

technical field [0001] The invention relates to a method for quickly acquiring abnormally used land, which belongs to the field of signal and information processing. Background technique [0002] With the accelerated development of industrialization and urbanization, the contradiction between man and land in our country is increasing day by day, the situation of cultivated land protection is becoming more and more severe, the contradiction between supply and demand of land is becoming more and more acute, and the violation of land laws and regulations, especially the violation of farmers' land rights and interests is very serious, which has become a problem that has long plagued my country's sustainable development. outstanding issues of the process. In order to effectively solve the outstanding problems in my country's land management, effectively protect the cultivated land, and ensure the red line of 1.8 billion mu of cultivated land, in addition to adopting strong legal a...
