Holmes Mining Consultants are a regulatory and permitting consultant specializing in the aggregate mining industry in BC.  Helping and guiding clients navigate the complex regulatory procedures in B.C. to successfully bring aggregate mining projects to fruition.  We help our clients be cost effective, thoughtful and successful with their applications, saving time & money.

Remote sensing (drone work) is a growing part of the business that supports the project applications and could end up being a stand-alone business in itself delivering drone services outside our traditional business.


Drones with LiDAR Technology


How Does LiDAR Work?

HMC uses LiDAR also called 3D laser scanning—means “Light Detection and Ranging”. Simply put, a typical lidar sensor emits pulsed light waves into the surrounding environment. These pulses bounce off surrounding objects and return to the sensor. The sensor uses the time it took for each pulse to return to the sensor to calculate the distance it traveled.

Drone LiDAR

Is a technology that uses laser to measure the positions of elements. It uses oscillating mirrors to send out laser pulses in many directions to generate a “sheet” of light as the drone moves forward.  Through measuring the timing and intensity of the returning pulses, it can provide readings of the terrain and of points on the ground.

Essentially, the LiDAR emits a laser pulse towards the surface, then the laser is reflected on the surface and returns to the sensor. Then the laser sensor measures the time traveled and calculates the distance between the LiDAR pulse and the surface. This process is carried out for a substantial number of points per second. For typical LiDAR by drone, this number of points varies between 18,500 and 600,000 points per second to create accurate data.


If you’re surveying land with dense vegetation where light pulses can still penetrate between branches and leaves, lidar yields high vertical accuracy. This is a significant advantage over photogrammetry, as photogrammetric surveying will only produce high vertical accuracy when there is sparse vegetation on site.
