Photogrammetry
Photogrammetry is a method of measuring and mapping areas using photographs, typically taken from aircraft, drones, or satellites. It's like taking precise measurements from pictures instead of measuring things directly on the ground. Forestry professionals use this to count trees, measure forest areas, and track forest health without walking through every part of the forest. Think of it as creating detailed 3D maps from photos that can show everything from tree heights to the spread of disease in forests. This saves time and allows for monitoring large areas that would be difficult to check on foot.
Examples in Resumes
Used Photogrammetry and drone imaging to map 5,000 acres of forest land
Created detailed forest inventory reports using Photogrammetric analysis
Led Photogrammetry projects to assess post-fire damage in national forests

Senior Level Questions
Q: How would you plan a large-scale forest inventory project using photogrammetry?
Expected Answer: A senior should discuss project planning steps including choosing appropriate equipment (drones/aircraft), considering weather conditions, ensuring proper image overlap, and managing data processing for large areas. They should mention quality control measures and team coordination.
Q: What methods do you use to ensure accuracy in photogrammetric measurements?
Expected Answer: Should explain ground control points, the importance of proper camera calibration, image overlap requirements, and how to verify results. Should mention experience with different weather and lighting conditions.
Mid Level Questions
Q: What factors affect the quality of aerial photographs for forestry assessment?
Expected Answer: Should discuss weather conditions, time of day, seasonal changes in vegetation, camera settings, and flight planning. Should show understanding of how these factors impact measurement accuracy.
Q: How do you process photogrammetry data to create forest inventory reports?
Expected Answer: Should explain the workflow from photo collection to final reports, including data processing steps, software used, and how to interpret results for forest management decisions.
Junior Level Questions
Q: What basic equipment is needed for forestry photogrammetry?
Expected Answer: Should be able to list basic tools like cameras, drones, GPS units, and common software. Should understand basic safety and operational procedures.
Q: How do you prepare for a basic aerial photography mission?
Expected Answer: Should describe basic flight planning, weather checking, equipment checks, and safety procedures. Should know basic regulations for drone or aerial operations.
