Mobile Mapping

About Mobile Mapping

Mobile Mapping is the process of capturing geospatial data from a moving vehicle mounted with high-precision measurement sensors resulting in the production of survey grade maps, drawings and models.

Data Capture Process

Mobile Mapping utilises a combination of geospatial tech and sensors to ensure coverage, precision and accuracy. LIDAR Scanners and 360-degree cameras are the primary methodologies for data capture which are controlled by positional sensors such as GNSS and IMU which record the position and trajectory of the LIDAR/ Camera platform.

Use Cases

Road Topographic Surveys – Mobile Mapping is most advantageous and cost effective on road projects and in particular when applied to larger route surveys. Mobile Mapping can cover many kilometres in a fraction of the time required for traditional survey techniques and negates the requirement for costly traffic management. Ground Control Points are often coordinated along the route to control the dimensional accuracy of the data.  

Rail Topographic Surveys – Large scale rail projects can be carried out efficiently by mounting a Mobile Mapping platform to a trains, enabling surveys to be conducted at commuter speeds with minimal disruption as the main focus. It can also be mounted on a customized rail vehicle, allowing for slower-paced operation to maximize data coverage. Additionally, it can be mounted on a rail trolley and manually operated for specific tasks such as gauge surveys.

Rail Gauge Surveys – Rail trolley mounted with LIDAR and gauge measurement technology is manually operated by surveyors on site to survey the gauge, alignment and position of the rail simultaneously under a single pass. These works are often carried out at night under a rail possession.

River Structures - Survey of river and watercourse structures using Mobile Mapping equipped boat is generally required in cases where it is not possible to safely survey the data from the embankment, such as certain bridge elevations or structural supports beneath a jetty.

Infrastructure Asset Management - Mobile Mapping is the most efficient methodology for capturing position, height, level and metadata on assets such as lamp posts, road signs, traffic lights, service covers and similar which can be utilised in GIS packages in development of Smart City deliverables.
