Field capture + geospatial processing

Surveying technology for difficult sites and complex data

Lanthier & Gilmore maintains advanced field and processing systems for projects that require efficient coverage, dense existing-condition data or coordinated three-dimensional deliverables.

Practical scope guidance

Define the required result before choosing the method.

Property records, site conditions, intended reliance and requested deliverables all affect the professional work involved.

Independent positioning infrastructure

Our own VRS infrastructure supports GNSS field operations across our working area. Project control, site conditions and required tolerances still determine the appropriate observation and checking methods.

Aerial imagery and LiDAR

A fleet of DJI aerial platforms supports high-resolution imagery and LiDAR capture for suitable sites. Depending on the assignment, aerial data can document terrain, structures, vegetation, corridors and other features over areas that would be inefficient or difficult to capture by one method alone.

Terrestrial scanning and point clouds

Ground-based scanning and full point-cloud processing allow dense three-dimensional site records to be registered, checked and prepared for engineering, design, utility and existing-condition workflows.

Accuracy belongs to the scope

Centimetre-level mapping may be achievable when the control, sensor, geometry, environment and processing workflow support it. We define the required result first, then select and verify the methods appropriate to that deliverable.

Equipment operated in-house

Aerial, LiDAR and terrestrial survey systems.

Lanthier & Gilmore owns and operates an enterprise aerial fleet, LiDAR, terrestrial scanning, VRS infrastructure and full point-cloud processing. We can combine methods to suit the site and the required deliverable.

Colourized point cloud of an urban block with buildings, trees and utility infrastructure — **Urban point-cloud processing**Registered three-dimensional data preserves buildings, streets, vegetation and overhead infrastructure in one coordinated site record.

Colourized point cloud showing a bridge, utility poles and overhead power lines — **Corridor and utility detail**Dense capture can retain the relationship between bridge geometry, terrain, poles and conductors for detailed mapping workflows.

Survey drone prepared for aerial capture at Sherkston Shores — **Aerial field setup**Aerial work still begins with field planning, site control, safe operation and a deliverable defined around the project need.

Survey equipment and an Argo vehicle at a remote winter field site — **Difficult-site access**Remote and seasonal conditions affect how crews reach the work and which combination of instruments is practical on the ground.
