GRAND CANYON — Beginning this spring, Grand Canyon National Park will partner with the U.S. Geological Survey (USGS) on an aerial LiDAR (Light Detection and Ranging) data collection project, with funding support from Grand Canyon Conservancy. This cutting-edge remote sensing technology uses laser pulses to generate highly accurate, three-dimensional maps of the landscape—providing valuable data on topography, vegetation, and geologic features.
LiDAR data collection will take place between May 10 and May 31, weather and ground conditions permitting. Approximately 30 to 35 flight missions will be conducted using fixed-wing aircraft (similar to the one pictured at right) flying at altitudes between 7,850 and 13,500 feet. While minimal disruption is anticipated, staff and residents should be aware of increased aircraft activity throughout the survey window.
In addition, helicopter flights are scheduled from May 19 to May 24 to access 51 ground control points needed to ensure spatial accuracy of the data. These reference points are critical for aligning the LiDAR data with real-world coordinates.
This project will enhance our ability to monitor landscape changes, support resource management, and improve future planning efforts across the park. To learn more about this project, visit Grand Canyon Conservancy’s website at www.grandcanyon.org.
