A remote sensing monitoring method for the whole process of land reclamation and reclamation area development

Abstract

A remote sensing monitoring method for the whole process of land reclamation and reclamation area development belongs to the surveying and mapping engineering field. In this technology, the remote sensing images and the actual land reclamation area are used to construct the remote sensing image characteristic database of land reclamation increment period, settlement period, stock period and salesperiod, and then the remote sensing image database is used to classify and extract the land reclamation area in each remote sensing image sequence. The land reclamation regions extracted from each phase of remote sensing images are classified and assigned values, and then converted into grid format for spatial superposition. According to the spatial superposition of grid numerical, the whole process of land reclamation and development of each grid unit is analyzed, a remote sensing monitoring result map of the whole process of land reclamation and regional development is made, and the space-time holographic process of the land reclamation and regional development is analyzed and gathered. The monitoring method accurately monitors the holographic process of land reclamation, improves the management efficiency of marine natural resources, and achieves the purpose of intensive and efficient use of marine spatial resources.

Description

technical field [0001] The invention relates to a remote sensing monitoring method for the whole process of developing a land reclamation area, which belongs to the field of surveying and mapping engineering. It mainly uses high spatial resolution remote sensing images to carry out continuous monitoring of the reclamation area, and through the spatial overlay of the monitoring results, it is a remote sensing monitoring engineering technology that reflects the temporal and spatial holographic process of the development of the reclamation area. Background technique [0002] Land reclamation is the human marine development and utilization activity that reclaims the ocean to form land for social and economic development. In recent years, with the rapid social and economic development in developed coastal areas, there are more people and less land, and land resources are increasingly scarce, and the development space is severely limited. In order to expand the development space,...

AI Technical Summary

Problems solved by technology

However, the current reclamation monitoring only uses remote sensing images to simply monitor the distribution area and occupied sea area of ​​reclamation, which cannot reflect the development sequence process of reclamation areas, and is not conducive to the fine management of reclamation areas.
