- Pipeline Locating and Mapping
All Stone Lake pipeline-locating personnel are accredited with the Enform Buried Facilities Locating course and are experienced in the field of seismic pipeline locating and mapping. All our field personnel are certified with Standard First Aid, H2S Alive, WHMIS, Collision Avoidance Driving and Quad Safety.
Stone Lake primarily utilizes Gasonic RD400 and RD4000 pipeline locating units for locating the pipelines as well as Trimble GeoXH GPS units to map the location of the pipeline(s) to a sub-metre level of accuracy.
On 2D or 3D geophysical programs, maps complete with the source and receiver locations, as well as the location of the pipeline(s), are standard deliverables. Additional field culture data can be collected, such as buildings, water wells, roads and trails. Depending on your particular requirements, all of this information can be displayed on topographic, orthophoto, satellite imagery, government digital elevation model (DEM) or LiDAR data backgrounds, through the services of our field mapping and GIS department.
- Advancing - Line Pushing and Field Mapping
At Stone Lake we provide expert line pushes with GPS capabilities on green-area programs. We use the latest mapping programs such as ESRI, OZI and Mapwel software, along with the appropriate components of the following data: digital topographic, orthophotos or satellite imagery, government digital elevation models (DEM) or LiDAR data, including bare earth, vegetation height or full feature, to ensure efficiency in the field. We can then plan the optimal line locations for your seismic program.
Our field mapping crews can locate and map utilities or facilities, and accesses, as well as generate buffers, as required, for water features, etc. Utilizing this information, we can then provide an accurate field culture/hazard assessment map prior to any actual cutting taking place on the ground.
Proper lead-time allotted for scouting and field mapping at the onset of the program generates efficiencies in the line-cutting operations and throughout the program. The line pushes stream data to and from the GPS units mounted in the line-cutting machines and line slashers. This information is transferred nightly to the mapping coordinator, who produces up-to-date field maps with the following day’s planned production for all phases of the operation.
- Enhanced Surveying Technologies
Stone Lake’s commitment to continuous enhancement of our technology and expertise has provided capabilities that enable the company to efficiently map and survey all types of terrain. We follow field procedure standards that ensure consistency in all our deliverables. The following is an overview:
Global Positioning System (GPS) Surveying
In areas with satellite reception, Stone Lake uses the Leica Viva GNSS and GX1230GG dual-frequency receivers, which can provide centimeter-level accuracy in areas with strong satellite reception.
Inertial Navigation System (INS) Surveying
This is one of our most specialized services: accurate surveying where satellite reception is blocked or compromised. This can occur in obstructed areas or rough terrain. INS capability also allows us to conduct accurate below-ground surveys, such as in underground mines, and heavily canopied forested areas.
Real-Time Kinematic (RTK) Surveying and Barometry
This is another specialized technique, ideally suited for tackling patchy, medium to heavily canopied areas. We have access to methodologies that integrate barometry instrumentation with GPS. We then apply sophisticated processing algorithms to achieve required industry accuracies under such conditions. Our powerful suite of positioning and tracking methods – GPS, INS, RTK and barometry – allows us to conduct accurate, seamless surveys virtually anywhere.
We provide on-site technical support trailers for GPS/INS surveys as well as to minimize downtime. To avert the need for snowplowing, the survey crews use tracked ATVs and UTVs. To ensure safety and minimize downtime, we employ a licensed mechanic to service our fleet of up to 20 4x4 Vehicles, 50 ATVs, 20 UTVs, 30 trailers and 15 snowmobiles. The ATVs and UTVs can be equipped with tracks or wheels to suit the prevailing ground conditions.
Employees are provided with the latest computers, printers and software to accomplish timely processing and transmittal of the data to the client. To enhance safety and productivity, employees are equipped with cell phones and/or PDAs. Direct communication capability is an important safety feature for working in remote areas.
- 3D Laser Scanning
Stone Lake’s 3D laser surveys measure thousands of spatially accurate positions per seconds, dramatically increasing productivity while reducing surveyors’ exposure to potentially hazardous conditions and/or terrain. Complex facilities or large mines can be surveyed rapidly, outdoors and indoors. The resulting point cloud data is available with a short turnaround time.
The resulting digital files can be viewed as crisp visual images containing embedded coordinates, enabling millimetre-accurate measurements among any survey points. The files can be exported into various CAD and GIS software and developed into accurate 3D renderings.
Sites and facilities are thereby rendered “as-built”, showing real specifications. You no longer have to make do with outdated blueprints or manual measurements. This reduces your asset management risks and aids in planning facility maintenance, upgrades or expansion.
3D laser scans are stored on our web-enabled TriliGIS system, where they can be integrated with your existing digital maps and other asset information, and are available on-line, 24/7 to any authorized user.
Long-range or short-range
Our 3D laser scanners are light and compact – mounted on a pickup truck, SUV or UTV. Surveys can be performed day or night.
Long-range (utilizing MapTek I-Site 8800 laser scanner):
- For large outdoor areas
- Typical operating range: 1,400 metres
- Scans up to 8,800 points per second
- 70 megapixel digital images
- Centimetre accuracy
Short-range (utilizing Trimble TX5 laser scanner):
- For precise indoor and outdoor surveying
- Typical operating range: 45 metres
- Scans up to 976,000 points per second
- 70 megapixel digital images
- Millimetre accuracy
Our experienced, qualified personnel can perform 3D laser surveys anywhere across the Sahtu region.
The applications of 3D laser surveys are very wide-ranging, including:
Oil and Natural Gas
Captures the layout, dimensions and fit of pipeline facilities and oilfield related equipment as they are today.
Enables efficient, accurate calculation of overburden removal and fill requirements, and eases matching of survey points to construction drawings.
Pumping stations, tank farms and control houses can be viewed in detail. 3D rendering allows you to perform various types of collision analysis.
Knowing exactly what volumes need to be moved – and where – eases remediation/reclamation planning, while the detail acquired makes the process more cost-effective.
Mining and Stockpiles
Safe and efficient inventory calculation, no matter how large your site and how much material is being moved. You’re no longer just estimating, you’re measuring.
Scan culturally sensitive sites for archiving and preservation, all the while maintaining a safe distance without disturbing the area.
In rugged terrain, no traditional surveying method comes close to the safety, efficiency and accuracy of 3D laser surveying.
Increase operational safety by not having to send surveyors into potentially dangerous situations to capture data.

- Extensive Final Plan Package
Stone Lake’s GIS department mapping team compiles various data sets to create accurate final plan maps. Our survey crews input the line-width data in their data collectors as they survey each line. This enables us to provide more accurate final plan data. Our mapping team can then perform quality control and integrate:
- The field survey line-width data;
- Advance crew, digital line width/cut-type and access data obtained from the line cutting equipment GPS units; and
- Government data sets.
The result is compilation of accurate final plan packages.
