StreetMapper Portable

StreetMapper uses well-proven laser scanning technology to capture the position of up to 300,000 3D point measurements per second whilst in motion. The typical positional accuracy is better than 2cm and the point-to-point accuracy within the data is 1cm.

 

Precision Navigation

The onboard navigation system includes a Global Navigation Satellite System (GNSS) receiver, a fibre optic gyro-based Inertial Measurement Unit (IMU) and the latest Direct Inertial Aiding (DIA) to assist in areas of poor GPS reception. StreetMapper 360 and StreetMapper Portable are the only systems on the market to offer this level of precision navigation, which has been proven to increase the speed with which the GPS receiver gets back to high positional accuracy after a loss of signal by up to 5 seconds.

 

Deliverables

An inherent feature of LiDAR data is that it is acquired, processed and delivered in a digital format, making it very easy to work with and to create data products that meet a wide range of needs. The system is easy to mobilise and immediately after the survey the data is processed to provide point data with XYZ position and reflective intensity. Depending upon the customer’s requirements, the data can be processed and analysed further:

  • Classification of laser data (for example ground, vegetation, buildings, wires)
  • Vectorisation of laser data
  • Measurement of features
  • 3D modelling and texturing

 

Optical DME for best results

Compared to the wheel Distance Measurement Equipment (DME), the optical DME has the advantage of not being influenced by changes in the radius of the wheel. These changes of the effective radius (caused e.g. by temperature changes) introduce an unknown scalefactor to the measurement. StreetMapper uses optical DME to achieve best results!

 

Ease of Use

StreetMapper 360 and StreetMapper Portable have dedicated control screens that shows status information and allows the data capture parameters to be adjusted. Operations that require a higher level of skill, such as GPS processing, are undertaken post-mission using sophisticated software for processing the collected navigation data, laser survey measurements and camera or video images. StreetMapper 360 and StreetMapper Portable also include mission control and route planning software.
