LiDAR
LiDAR (Light Detection and Ranging) is a surveying method that uses laser light to make detailed 3D maps of landscapes and forests. Think of it like taking a very accurate 3D photograph that can see through tree canopies. Forestry professionals use LiDAR to measure tree heights, count trees, map forest areas, and plan forest management activities without having to physically visit every location. It's similar to radar but uses light instead of radio waves. The technology can be used from aircraft, drones, or ground equipment, making it a valuable tool for forest inventory and planning.

Example Interview Questions
Senior Level Questions
Q: How would you plan a large-scale forest inventory project using LiDAR?
Expected Answer: A senior specialist should discuss project planning steps including flight planning, data collection timing, quality control measures, and how to integrate ground truthing with LiDAR data. They should also mention cost considerations and accuracy requirements.
Q: What methods do you use to validate LiDAR data accuracy?
Expected Answer: Should explain ground verification processes, statistical analysis methods, and how to ensure data meets forest inventory standards. Should mention experience with different validation techniques and quality assurance protocols.
Mid Level Questions
Q: How do you process raw LiDAR data for forest inventory purposes?
Expected Answer: Should be able to explain the basic steps of cleaning and processing LiDAR data, including point cloud classification, creating terrain models, and extracting forest metrics like tree height and density.
Q: What factors affect LiDAR data quality in forest environments?
Expected Answer: Should discuss how weather conditions, seasonal changes, forest density, and equipment settings can impact data quality, and how to account for these factors in planning.
Junior Level Questions
Q: What is LiDAR and how is it used in forestry?
Expected Answer: Should be able to explain that LiDAR is a remote sensing technology that uses laser pulses to measure distances and create 3D maps, and describe basic forestry applications like measuring tree heights and mapping terrain.
Q: What are the basic components of a LiDAR dataset?
Expected Answer: Should understand point clouds, classification systems, and basic file formats used in LiDAR data, and be able to explain these concepts in simple terms.
