Mobile Mapping Systems (MMS) are advanced lasers affixed to moving vehicles that scan and capture 360 degrees of their surroundings. We use this LiDAR technology to measure objects down to the centimetre, by millions of points per second, collecting data on literally every visual component. Clients can easily access this new class of digital data for a totally immersive and accurate 3D view of their project. At GeoVerra, we use the best of the best. Our complete mobile mapping solution combines leading-edge hardware with intuitive field software and a powerful, integrated office software workflow. This efficient, high-performance mobile mapping system rapidly captures laser scans and images, both panoramic and multi-angle, as you drive, making it ideal for large survey, engineering projects, and asset management.

Laser scanning emits laser pulses toward coordinates, measuring the distance between the device and its target. With 3D scanning, we’re able to collect thousands of data points per second, in a fraction of the time it takes using conventional survey methods and provides a means of storing geospatial data for informed decision making and optimized operations. From the most advanced traditional scanners to the new wearable scanners that can be used to capture in greater details anywhere accessible by foot, these unobtrusive scanners are safe, thorough and cost-efficient; reducing facility downtime and return visits to the site.

Unmanned aerial imaging is a proven and trusted technique for collecting precise geospatial data with remote (LiDAR) and photogrammetry (RGB) sensors. UAVs help us perform quick, high-definition surveys (HDS) across large, complex, and even hazardous areas while keeping everyone out of harm’s way. Using the latest fixed-wing and multi-rotor drones, our licensed pilots can fly different types of payloads, and collect and model LiDAR data during flight for real-time structural and infrastructure inspections.

GeoVerra’s Flight Management Program was developed using FLYsafe by AIRmarket, a platform built with large enterprises in mind. It allows our UAV pilots to focus on the task at hand – collecting data for your operations. The enterprise platform supports site assessments and operations in compliance with Transport Canada and supports Beyond Visual Line of Sight (BVLOS) missions.

Bathymetric surveys capture detailed data in a fraction of the time it takes traditional survey methods. We use manned and unmanned boats with RTK GNSS receivers, which take in the normal signals from global navigation satellite systems along with a correction stream to achieve positional precision down to the centimetre. Tethered to single-beam or multi-beam echo sounders, they collect and record accurate depth readings. Our field crews are Swift Water Safety certified and equipped with the technology to access watercourses of any size and complexity, safely, efficiently, and non-invasively. This means reduced time on the water and fewer return visits to the site.

Ground penetrating radar (GPR) technology is a non-invasive, non-destructive method of geophysical surveying that uses radar pulses triggered by odometer movement to image and produce a 2D cross-section of the sub-surface. Compared to other techniques, like infrared thermography, ultrasonic, or microwave, GPR’s penetrating power can detect defects, deterioration, and anomalies at greater depths — perfect for buried utility or buried object locating, archaeology, bridge inspections, ice thickness mapping, and concrete inspections.
GPR is relatively efficient at collecting large amounts of data and is highly accurate when operated by our team of skilled professionals.

We utilize metric digital cameras and close-range photogrammetry to provide for progress, change, and condition monitoring. Our technologies create dense point clouds based on image-matching or Surface from Motion (SfM) algorithms. Effective in moist environments, the survey-grade accuracy point clouds can be compared to the original design or to point clouds at different epochs to monitor structural deformations in transportation corridors, buildings, bridges, dams, and other infrastructures subjected to extreme events or natural aging.
