Mobile laser scanning is new technology that is ideal for surveying various types of infrastructure including roads, rail, pipelines and power lines.

Surveyors @ Work high definition 3D mobile mapping system delivers a high density point cloud with colourful image overlay for the ultimate in feature recognition and mapping details.

Our system overcomes the challenges of mapping 3D features at a high level of accuracy. Accurate vehicle positions are obtained using three technologies: a dual frequency GNSS receiver establishes a geospatial position; an inertial measurement unit (IMU) provides vehicle attitude and connection to the vehicle or external wheel encoders obtains odometry information. These three technologies work together to sustain a highly accurate 3D position for the vehicle even in locations where satellite signals can be blocked by obstructions such as buildings, bridges or tree lines.

The standard IP-S2 HD system includes one sensor head of LiDAR containing 64 lasers oriented to cover roadside features up to 100m away. A 360˚ spherical digital camera is included to collect images at fixed distance intervals. Optional high resolution still digital cameras are available for enhanced object viewing. All sensor inputs are recorded and time stamped to a common clock driven by the IP-S2 HD.

Geoclean, Surveyors @ Work’s powerful software, will post-process the geo-referenced LiDAR and/or digital imaging data into a viewable 3D image representation which can be exported into 3rd party software. GNSS data can be post-processed against a permanent or temporary base station for higher accuracy. Spatial Factory software provides a simple interface for combining, viewing and working with your various sensor data from the IP-S2 HD.

The IP-S2 HD quickly provides high accuracy data and dynamic imaging for any mapping project. The vehicle-mounted system can map data at normal travel speeds for roadway surface condition assessments and roadside feature inventories. Safety is increased by removing pedestrians from the travelled lanes. Other applications include pipelines, railways, utility corridors, and waterway.

Full-colour, high resolution, high-density point clouds dramatically increase efficiencies in the following areas:

utilities

Surveyors @ Work’s IP-S2 effectively addresses utility infrastructure needs such as mapping electric and telephone grids in both urban and rural area. In instances where it has been cost prohibitive to collect information and attribute data due to the time consuming, labour intensive nature of traditional data collection techniques, the IP-S2 HD now provides a fast and affordable means to create accurate map data. The amount of ground that can be covered in a day is greatly increased and the number of personnel required to do the job decreases in magnitudes. The opportunity for human input error is also greatly decreased. The detail obtained in a high definition point cloud from the IP-S2 HD allow overhead power lines to be captured which may get missed with standard definition mobile mapping systems. As a result, management agencies are able to make accurate and quick maintenance decisions right from the office saving time and costly mistakes.

GIS asset management

Creating a GIS database of assets can be an overwhelming task as the number of items to map can be immense. Surveyors @ Work’s IP-S2 HD can simplify the task by obtaining data on all assets in a particular area as the truck drives through. The high definition point cloud ensures that data on smaller utilities such as water vales is obtained. In addition to location information, asset managers can view descriptive details of the assets using the colourised point cloud image overlay. It is not necessary to predefine the attributes values needed in the GIS database before fieldwork. All information is in the IP-S2 HD database and can be extracted at any time after the field work is complete.

transportation

Using GPS alone for data collection of transportation facilities such as roads, highways, tunnels and overpasses can often pose problems as GPS signals are blocked by nearby buildings and structures. Surveyors @ Work’s IP-S2 HD becomes a great solution for transportation mapping as the combination of GPS and IMU sensors allows for continued accurate position updates in GPS outage areas. The IP-S2 HD vehicle can also get data under overpasses and in the areas where aerial fly-over methods produce no data. The detailed point cloud from the IP-S2 HD allows for data collection of small objects such as individual rail ties for railway applications. A combination of the high definition laser and the speed and accuracy of the IP-S2 HD make the system a perfect fit for transportation mapping applications such as highways, railways and roads.
