Prompt Description

Title Suggestion: Figure 2. Framework Diagram of Soil Particle Size Inversion Mechanism Based on Multi-Angle BRDF Features. Content Conceptualization: Top (Data Input): Showcase multi-angle satellite imagery acquired from satellites (e.g., Terra satellite, with MISR and MODIS sensors indicated). Middle (Core Processing): Input the multi-angle observation data into a "BRDF Model" module (e.g., a semi-empirical kernel-driven model). The model outputs several key physical model parameters (e.g., fiso, fvol, fgeo, or represented as k1, k2, k3). Bottom (Inversion Output): Represent the "Novel Photometric Parameter Index Construction" using a formula or chart box (e.g., calculate an index P = fvol / fgeo using model parameters). Finally, output the final spatial distribution map of soil particle size through a "Particle Size Inversion Model" (e.g., a statistical model or a machine learning model). Arrow Flow: Clearly connect the above modules with arrows to form a complete technical flowchart.
