Photogrammetry
Photogrammetry is a method of creating detailed 3D maps and measurements from photographs. It's like taking many pictures of something (like a mining site or construction area) from different angles and using special software to turn these into accurate 3D models and maps. This technique is valuable in surveying because it's safer and faster than traditional ground-based measurements, especially in hard-to-reach areas. Companies use it for things like mapping mines, monitoring construction progress, or checking the condition of roads and bridges. Similar approaches include LiDAR scanning or drone surveying, but photogrammetry specifically refers to getting measurements from photographs.

Example Interview Questions
Senior Level Questions
Q: How would you plan a large-scale photogrammetry project for a mining site?
Expected Answer: A senior candidate should explain project planning including flight planning, ground control points, equipment selection, weather considerations, and quality control measures. They should mention coordination with site operations and safety protocols.
Q: What methods do you use to ensure accuracy in photogrammetric measurements?
Expected Answer: Should discuss ground control points, proper image overlap, camera calibration, and quality checking procedures. Should mention dealing with different terrain types and environmental conditions.
Mid Level Questions
Q: What software do you use for photogrammetry processing and why?
Expected Answer: Should be familiar with common software packages and able to explain their strengths and uses for different types of projects. Should understand basic processing workflows.
Q: How do you handle challenging surveying conditions?
Expected Answer: Should discuss solutions for poor lighting, difficult terrain, or weather issues. Should mention alternative methods when standard approaches aren't suitable.
Junior Level Questions
Q: Can you explain the basic principles of photogrammetry?
Expected Answer: Should be able to explain in simple terms how photographs are used to create measurements and 3D models, and basic concepts of image overlap and camera positions.
Q: What safety considerations are important in field work?
Expected Answer: Should demonstrate awareness of basic field safety protocols, equipment handling, and site safety requirements for surveying work.
