PATC (Precision Approach Terrain Chart)
Accurate digital terrain and obstacle datasets to ensure safe flight operations and compliance with global standards.
Our Story
What is eTOD?
Electronic Terrain & Obstacle Data (eTOD) provides a digital representation of terrain and obstacles, supporting a wide range of airborne and ground applications.
It includes:
Digital Terrain Model (DTM) → Bare earth elevation
Digital Surface Model (DSM) → Terrain with features like buildings, towers, and vegetation
✅ Ensures aviation safety, flight planning accuracy, and obstacle awareness.
