It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0026] Embodiment 1:

[0027] See also Figure 1 to Figure 2 , an embodiment of the present invention provides a land space monitoring method and system based on satellite remote sensing, the land space monitoring method and system based on satellite remote sensing comprising:

[0028] S1. Initial image acquisition: first input and determine the complete geographic coordinate information of the monitoring area, and obtain the initial image of the geographic area through satellite remote sensing technology based on the geographic coordinate information;

[0029] S2, input of target image: according to the obtained initial image as the bottom image data source, the geographical area target to be monitored is drawn and input according to the planning and design on the bottom image data source to obtain the target image as the top image data source. The input of the target image in S2 is drawn and input according to the planning and design by using satellite remote sensing simulation;

[0030] S3. Acquisition of intermediate images: Regularly acquire intermediate images of the geographical area through satellite remote sensing technology as the intermediate image data source;

[0031] S4, data monitoring and analysis: the intermediate image data source obtained in step S3 is placed between the bottom image data source in step S1 and the top image data source in step S2, and the three image data are mapped up and down, and multi-dimensional comprehensive data processing and analysis are performed to perform spatial monitoring and analysis of land resources. The S4 data monitoring and analysis includes changes in land resource utilization, vegetation coverage, topography, water body, etc.;

[0032] S5. Result output: Output the monitoring and analysis results in the form of charts, reports, etc.;

[0033] In S1, the initial image includes land use type, vegetation coverage, topography, water body distribution, etc., and after the image is acquired, the acquired remote sensing image is preprocessed, including radiation calibration, atmospheric correction, geometric correction, etc., to eliminate the distortion and error in the image, and the land resources information including land use type, vegetation coverage, topography, water body distribution, etc. is extracted from the processed remote sensing image by using remote sensing data processing technology and GIS technology;

[0034] The method is applied to a land space monitoring system based on satellite remote sensing, and the monitoring system comprises:

[0035] Data input unit: configured to input complete geographic coordinate information of the monitoring area, and to input a depiction input of a geographic area target to be monitored on the underlying image data source;

[0036] A remote sensing image receiving unit: configured to acquire an initial image and an intermediate image;

[0037] Remote sensing image processing and analysis unit: configured to be used for data monitoring and analysis, and to analyze and judge the acquired and input image data;

[0038] Result output unit: configured to receive data from the remote sensing image processing and analysis unit, and output the data in a chart or report format that can be recognized by this system.

[0039] It should be noted that: when it is necessary to input the geographic coordinates of the location of the geographic area, the initial image is obtained by using satellite remote sensing technology, and the remote sensing image receiving unit is used to receive satellite remote sensing image data, and then the remote sensing image data of the planning and design is input. Specifically, when the area is monitored for returning farmland to forest, the area of ​​the planting fields and forest land in the target area is specifically highlighted, and then the planning and design goals of returning farmland to forest are drawn into a target image, and the initial image and the target image are input into the remote sensing processing and analysis unit as the bottom image data source and the top image data source. Then, in the process of implementing returning farmland to forest, the target area is regularly mapped using satellite remote sensing to obtain an intermediate image, and then the intermediate image is placed between the initial image and the target image, and a before-and-after comparison analysis is performed. The data results of the comparison and analysis are then displayed in a chart report format using a result output unit, and then viewed by accessing the system. While realizing the geographical land and resources monitoring of the target area, accurate remote sensing predictions can be made for the planning and design goals, providing accurate data support for scientific planning and management in the later stage.

[0040] In this embodiment: here, returning farmland to forest can be replaced with monitoring projects such as sand control, desertification control, farmland protection, urban road and rail transit planning according to the specific national land design plan, so as to carry out targeted monitoring of land resources.

[0041] Furthermore, when using satellite remote sensing technology to obtain image data, aerial photography and manual on-site photography can be used to re-shoot and correct the images obtained by satellite remote sensing, thereby improving the accuracy of satellite remote sensing monitoring.

[0042] Furthermore, the above-mentioned monitoring system also includes a remote sensing image simulation prediction unit: it is configured to simulate and predict the time to reach the target image in combination with the change interval time of the initial image data source and the intermediate image data source, so as to facilitate the supervision of the planning and design process. When the later intermediate image data is lower than the simulated predicted image, a red warning is issued for the implemented project to remind the relevant responsible personnel to speed up the project progress.

[0043] The working principle of the land space monitoring method and system based on satellite remote sensing provided by the present invention is as follows:

[0044] When it is necessary to input the geographic coordinates of the location of the geographic area, use satellite remote sensing technology to obtain the initial image, use the remote sensing image receiving unit to receive satellite remote sensing image data, and then input the remote sensing image data of the planning and design. Specifically, when the area is monitored for returning farmland to forest, the area of ​​the planting fields and forest land in the target area is specifically highlighted, and then the planning and design target of returning farmland to forest is drawn into a target image, and the initial image and the target image are input into the remote sensing processing and analysis unit as the bottom image data source and the top image data source. Then, in the process of returning farmland to forest, the target area is regularly mapped using satellite remote sensing to obtain the intermediate image, and then the intermediate image is placed between the initial image and the target image for comparison and analysis. Then, the data results of the comparison and analysis are displayed in a chart report format using the result output unit, and then can be viewed by accessing the system. While realizing the monitoring of the geographical land resources of the target area, the planning and design targets can be accurately predicted by remote sensing, providing accurate data support for scientific planning and management in the later stage.

[0045] The monitoring system further includes a remote sensing image simulation prediction unit: it is configured to simulate and predict the time to reach the target image in combination with the change interval of the initial image data source and the intermediate image data source, so as to facilitate the supervision of the planning and design process. When the later intermediate image data is lower than the simulated predicted image, a red warning is issued for the implemented project to remind the relevant responsible personnel to speed up the project progress.
