Feiyan Remote Sensing Susong County Surveying and Mapping Project Successfully Passed Acceptance

May 29, 2023

Background Of The Project

Susong County Natural Resources and Planning Bureau has followed the development trend of digital economy and digital city in recent years, scientifically grasped the new development stage, implemented the new development concept, served to build a new development pattern, and launched the Susong County Geographical Surveying and Mapping Comprehensive Service Construction Project . The project fully combines the development needs of Susong County, and incorporates digital aerial photography, lidar aerial photography and oblique aerial photography into the service content, intending to promote the deep integration of real-scene 3D data and natural resource business, and effectively play the role of real-scene 3D "unified base map" .

Project Status

Feiyan Remote Sensing was honored to undertake this project, and obtained high-definition image data of 2,370 square kilometers in Susong County through a 450-megapixel digital aerial camera and a laser radar aerial camera with a laser emission frequency up to 2000KHz.

Combined with the high-precision digital elevation model, construct a terrain-level 3D model of the large scene in the whole area, and implement close-range oblique aerial photography of key areas in Susong County by drones, realize the pilot test of the county-level 3D model, and provide a basis for the delineation of the three districts and three lines, the national territory Spatial planning and county-level refined management provide three-dimensional and intuitive decision-making basis.

Comparison of city-level real scene 3D models before and after refinement

At the acceptance meeting, the experts and leaders of the expert group unanimously agreed that the project passed the acceptance, which fully affirmed our company's ability to guarantee airspace coordination, personnel equipment, and aerial photography, and recognized the digital elevation model (DEM), digital orthophoto (DOM) and terrain-level and city-level real-scene 3D data results are conducive to the establishment of accurate data-based, data-based decision-making, data-based management, and data-based innovation through the use of geographic image data and various spatial planning data superposition analysis technologies. The governance model provides geographic information data support for the high-quality economic and social development of the county.

Data Application

At the same time, the project data is issued through the information platform of the Susong Resources and Planning Bureau (intranet computer terminal and mobile tablet terminal) and is directly used for land change investigation, satellite law enforcement investigation, land consolidation, project site selection, land and space planning compilation, For business work such as urban planning and design, various business data layers and high-definition images are superimposed and analyzed, which effectively assists front-line personnel to carry out various business tasks such as natural resources and planning management, and greatly improves work efficiency. In particular, it will play an important role in village planning compilation and natural resource supervision, providing solid geographic information data support for the high-quality economic and social development of counties, and is conducive to promoting the cross-regional and cross-level overall management, integration and collection of real-world 3D construction data. shared use.
