Ray tracing shade mask generation

Local Knowledge Graph (19 entities)

Description

A custom ray tracing algorithm that generates shade masks for hyperspectral imagery by calculating paths between the sun, ground points, and sensor using solar geometry, sensor view angles, and digital surface elevation models to identify shaded pixels.

Typical Equipment

• custom ray tracing algorithm
• lidar data
• digital surface elevation model

Output Measurements

• pixel-level shade masks
• illumination maps
