OxTS Georeferencer is a software tool developed by OxTS to combine INS navigation data with raw LiDAR data. It can be used alongside any OxTS Survey INS to create a georeferenced 3D Pointcloud.
OxTS Georeferencer takes a file collected with a LiDAR scanner (synchronised in real-time with an OxTS inertial navigation system), a processed navigation trajectory file from the OxTS INS, and some required configuration files, to create a LAS pointcloud file that can be viewed in many 3rd party LiDAR software packages.
Furthermore, thanks to our experience in calibration techniques, we have been able to develop a data-driven technique that helps system integrators and end users to start their work with confidence that their INS and LiDAR hardware has been installed precisely and accurately. This is the boresight calibration feature.
We offer the software free to download and provide example data for testing purposes. Using the data you can go through the process of georeferencing a pointcloud and use the boresight calibration tool to practise setting up your survey. You can download the test data and software from our support site and also view several support articles to help you get up and running – OxTS support site

LiDAR Surveying Brochure
OxTS inertial navigation systems provide users with absolute position and highly accurate inertial measurement information. This information allows them to georeference pointclouds from multiple LiDAR sensors.
These measurements help users increase survey repeatability, cut down the time to survey, intelligently analyse data, improve final results and increase project ROI.
Case Study: UAV Bridge Survey
OxTS Partner Dronezone were tasked with scanning an aging railway bridge to identify potential weaknesses in its structure.
Once they made the decision to survey the bridge using a UAV, there were a number of challenges they faced, specifically around payload weight, flight time, data processing and pointcloud accuracy. This case study details how they overcame them.
OxTS Georeferencer Process Flow
OxTS Georeferencer’s main function is to synchronise and fuse the OxTS INS and LiDAR data sets.
A LiDAR sensor can sense range to a target, but it has no internal knowledge of when or where it is, or where it has moved to since the last scan occurred. This is where the INS adds essential information:
- Nanosecond accurate time (Survey grade GNSS receivers)
- RTK/PPK accurate position (Survey grade GNSS receivers and tightly-coupled navigation engine)
- Accurate heading, pitch, and roll (Survey grade IMU sensors)
Thanks to live accuracies being reported as well, the data can be intelligently filtered based on estimated position/orientation accuracy of the INS, allowing you to perform less clean-up of the data in post-processing.
