01↗Topographic surveys
Capture detailed elevation and surface information for planning, engineering design, drainage analysis and site documentation.
UAS surveying & mapping
Map the ground.
Measure the change.
Drone surveying, photogrammetry and LiDAR mapping for engineering, mining, construction and environmental projects across British Columbia and Canada.
RTKPositioning workflows
3DMeasurable site models
CACanada-wide capability
Survey the full picture
More coverage.
Better context.
Ground crews need dependable site information—not disconnected imagery or unexplained numbers.
Ven-Tech plans each UAV mapping mission around the terrain, required accuracy, control network and final engineering use. Our drone surveying in BC and across Canada connects field capture, quality control and useful spatial deliverables in one disciplined workflow.

Surveying & mapping capabilities
From terrain
to usable data.
Every drone topographic survey, photogrammetry mission or drone LiDAR survey is designed around the decision and deliverable—not simply the flight.
01↗
02↗Volumes & stockpiles
Calculate stockpile, excavation and material volumes for inventory, reconciliation, cut-and-fill planning and progress tracking.
03↗Corridor mapping
Map roads, bridges, pipelines, shorelines and utility corridors with consistent aerial coverage and spatial context.
04↗Orthomosaic mapping
Create corrected, measurable site imagery for construction records, asset inventories, planning and change detection.
05↗DSM & DTM production
Develop digital surface and terrain models for elevation analysis, drainage, visibility, environmental and engineering workflows.
06↗LiDAR & 3D models
Generate point clouds, terrain detail and three-dimensional site records for complex surfaces, structures and vegetation conditions.
From capture to coordinates
Pixels become
project data.
Useful mapping is built through the complete workflow: mission geometry, positioning, control, processing, classification, QA/QC and delivery in the formats your team can use.
- 01 Planned flight lines and image overlap
- 02 RTK, PPK or ground-control integration
- 03 Surface, point-cloud and image processing
- 04 Verified, organized project outputs
Why UAS mapping
See the site.
Measure the work.
UAS mapping can add speed, repeatability and visual context to suitable engineering, construction, mining and environmental projects.
Efficient coverage
Capture broad or difficult terrain with a structured aerial data-collection plan.
Measurable outputs
Turn imagery and LiDAR into surfaces, models, contours, volumes and spatial records.
Repeatable monitoring
Use consistent control and mission plans to compare progress and change over time.
Connected workflows
Prepare data for engineering, survey, CAD, GIS and environmental project teams.
Accuracy & survey control
Accuracy starts
before takeoff.
The appropriate GNSS, ground control, checkpoint and processing workflow is selected around the site conditions, required deliverable and agreed accuracy target.
Professional scopeUAS-derived data supports engineering and survey workflows. Legal boundary or cadastral services require the appropriately licensed land-surveying professional.
RTK & PPK positioning
Real-time or post-processed GNSS workflows can be selected to support the project accuracy, site and control strategy.
Ground control points
Project control can be integrated where required to strengthen alignment, repeatability and deliverable confidence.
Independent checkpoints
Checkpoints provide a separate basis for evaluating the finished model against the agreed accuracy requirements.
Coordinate-system alignment
Data can be organized around the specified projection, datum, units and project coordinate framework.
QA/QC & accuracy reporting
Coverage, control, processing quality and check results are reviewed before project data is issued.
Engineering-ready formats
Outputs can be prepared for practical CAD, GIS, point-cloud, surface-model and reporting workflows.
Mapping workflow
From scope
to surface.
A disciplined process connects field capture to traceable, decision-ready spatial products.
Define the deliverable
Confirm the area, accuracy, coordinate system, features and required file formats.
Plan control & flight
Design the positioning, control, checkpoints, flight lines, overlap and site controls.
Capture & verify
Collect aerial and control data, then confirm field coverage and quality before demobilizing.
Process & deliver
Build, check and organize the mapping products for the intended CAD, GIS or project workflow.
Operational assurance
Technical capability.
Industrial discipline.
Ven-Tech’s mapping work is supported by the same contractor management, documentation and HSE framework used across our industrial, municipal, marine and infrastructure operations.

Common questions
Planning a
mapping project?
Send us the site, required accuracy and final deliverable. We’ll help define the appropriate capture and control strategy.
What accuracy can a drone survey achieve?+
Accuracy depends on the aircraft and sensor, flight altitude, terrain, vegetation, image geometry, GNSS method, ground control and processing workflow. Ven-Tech confirms the required accuracy and verification method before mobilization rather than applying one blanket specification to every site.
What is the difference between a DSM and a DTM?+
A digital surface model represents the visible upper surface, including buildings and vegetation. A digital terrain model is intended to represent the underlying ground surface after suitable classification and processing.
Can you calculate stockpile and excavation volumes?+
Yes. Suitable projects can be mapped to calculate stockpile, excavation, cut-and-fill and material-change volumes. The required control, surface definition, reporting method and comparison dates are agreed during project planning.
Which file formats can be delivered?+
Depending on the scope, deliverables may include georeferenced orthomosaics, point clouds, contours, DSMs, DTMs, textured 3D models, volume reports and common CAD or GIS-compatible formats.
Does this replace a legal boundary survey?+
No. UAS mapping can support engineering, environmental and survey workflows, but legal boundary and cadastral services must be completed or certified by the appropriately licensed land-surveying professional for the jurisdiction.
