What is lidar?

Lidar (Light Detection And Ranging) is a technology that captures three-dimensional information about the Earth’s surface. Pulses of light are sent from the sensor to the ground, and the time it takes for that pulse to encounter a feature and return to the sensor allows for an exact measurement of distance. That distance and the airplane’s precise location as measured by a GPS are combined to create the lidar point cloud.

Lidar is a fast and efficient way to gather accurate information about a project area. Each project is tailored to fit the client’s needs depending on the intended uses of the data.

Teledyne Optech Galaxy PRIME LiDAR System

One of the most advanced and efficient lidar sensors available, the Teledyne Optech Galaxy Prime sensor uses innovative lidar technology enhancements and incorporated flight and calibration software that significantly increases sensor performance and collection efficiency. These advancements directly tie into savings for customers.

  • The SwathTrak feature allows the sensor to adjust the field of view during collection so that the width of the swath is consistent over varied terrain
  • In areas of extreme relief, the sensor can achieve as much as a 40% reduction in the number of flight lines
  • The PulseTrak feature allows for the collection of consistent data

The Galaxy Prime provides consistency between adjacent points – on flat surfaces the variability of the points’ elevation is minor, allowing for a greater confidence in the accuracy of the data.
