Investigation and Monitoring

Business Overview

• Annual/Daily Land Change Survey

Strictly adhering to national technical standards, we leverage high-resolution remote sensing imagery, satellite-based law enforcement data, and results from the Third National Land Survey to accurately identify land use changes within the survey period. This includes completing polygon extraction, field verification, internal database construction, and final deliverable submission. The process comprehensively maps changes in land categories—including cultivated land, unused land, and construction land—as well as ownership boundaries, providing an authoritative base map for territorial spatial planning, governance, and farmland protection.

• Annual Survey and Monitoring of Forests, Grasslands, Wetlands, and Barren Lands

Conduct specialized monitoring of forest, grassland, wetland, and desertified land resources to assess their species composition, quantity, quality, distribution, and ecological status. Integrate multi-source remote sensing data with field plot surveys to dynamically track changes in resource availability, evaluate the effectiveness of ecological restoration, and monitor trends in desertification and rocky desertification. Deliver annual resource databases and statistical reports to support Forest Chief System assessments, carbon sink calculations, and ecological protection and restoration projects.
