Embodiment Construction

[0019] In order to make it more clear, the technical solution of the method and system for identifying change patterns in the dynamic monitoring of land use status will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0020] like figure 1 As shown, in one embodiment, a method for identifying changing patterns in the dynamic monitoring of land use status includes the following steps:

[0021] Step S102, acquiring the selected changed patch data.

[0022] Specifically, it is possible to discover and generate land use change patterns in advance based on satellite remote sensing images, on-site inspections, and law enforcement inspections. After these change patterns enter the system, the screening work can begin. First, the change map data set is obtained, obtained from A certain change patch data selected in the change patch dataset. The selected operation can be manually operated or automatically selected in sequence by the sy...

Abstract

The invention discloses a method for discriminating a changeable graphic spot in dynamic monitoring of a present situation of land use. The method comprises the following steps of: obtaining data of a selected changeable graphic spot; and comparing the data of the changeable graphic spot with a predefined condition of change types of the land use, and determining which change type of the land use the changeable spot belongs based on a comparison result. According to the method and system for discriminating the changeable graphic spot in the dynamic monitoring of the present situation of the land use, the selected change graphic spot is compared with the predefined condition of the change types of the land use to identify which change type of the land use the change graphic spot belongs, and manual work is unnecessary during the whole identification process, so that labor force is saved, and discriminating efficiency is improved; and the data of the changeable graphic data are compared with the preset condition, so that the discrimination accuracy is increased in comparison with that of the artificial judgment.

Description

technical field [0001] The invention relates to database technology, in particular to a method and system for identifying changing patterns in dynamic monitoring of land use status. Background technique [0002] In order to grasp the dynamic changes of the status quo of land use in a timely and comprehensive manner, a dynamic discovery mechanism for changes in the status quo of land use has been established. There are three main mechanisms for discovering changes. The second is to perform inspections, and to find changes through the daily inspection of land law enforcement patrol vehicles and report the changed maps; the third is to compare satellite images (satellite remote sensing images) (comparison and comparison of satellite images of two adjacent periods, Discover the range of change and tick the change map) to find the change map of the current land use status. [0003] After the map of the status quo of land use is reported, the reported map needs to go through inte...
