Land cover change monitoring method, system and device and storage medium

Abstract

The invention discloses a land cover change monitoring method, system and device and a storage medium, and the method comprises the steps: fusing SAR data and multispectral data to acquire obtaining afusion image; performing parameter calculation on a fused image to obtain image parameters; and performing change monitoring through a preset land cover dynamic change monitoring model according to the fused image and the image parameters to obtain a land cover change result. The SAR data and the multispectral data are fused, the fused image machine is subjected to change monitoring through the land cover dynamic change monitoring model, all-weather characteristics and texture characteristics can be obviously combined, spectral characteristics can also be combined, the analysis effect is finer, and the monitoring resolution and the monitoring efficiency are greatly improved. The invention can be widely applied to the field of land monitoring.

Description

technical field [0001] The invention relates to the technical field of geographic information technology, in particular to a land cover change monitoring method, system, device and storage medium. Background technique [0002] Land cover change monitoring is the process of determining the change monitoring of land cover objects in the same spatial area and spatial phenomena observed at different times, and extracting and describing object changes over time based on geographic information data or remote sensing images in different periods. The country's land policy and land measures must rely on timely, effective and accurate land data, which puts forward the requirement of dynamic change monitoring for the management of land use status. At present, in daily land management, management departments mainly use reports from lower-level departments, reports from land users, or registration data to passively learn about changes, lacking initiative. At present, remote sensing imag...

Problems solved by technology

At present, remote sensing images are widely used in land cover change monitoring due to their short acquisition time and wide coverage. However, they are limited by traditional monitoring methods. In terms of monitoring methods, traditional monitoring methods mainly use manual visual interpretation , not only the workload is heavy and the efficiency is low, but also the quality of change monitoring results is limited by the technical level of the interpreters
