INDOOR AND OUTDOOR STRUCTURED MONOMER RECONSTRUCTION OF CITY 3D REAL SCENE BASED ON NONLINEAR OPTIMIZATION AND INTEGRATION OF MULTI-SOURCE AND MULTI-MODAL DATA

This study used satellite data and artificial intelligence to estimate changes in soil weight and compaction across Thailand. It found that soil became denser between 2004 and 2009, suggesting possible land degradation. The method was more accurate than traditional techniques and can help monitor soil health across large areas to support better land and farming decisions.
