What is CHCNAV CoPre?

CHCNAV CoPre is the pre-processing software behind every CHCNAV LiDAR system. It takes the raw data from airborne, vehicle-mounted, backpack and handheld SLAM scanners and produces accurate, georeferenced and colourised point clouds – the starting point for every LiDAR deliverable.

Whether you fly an AlphaAir UAV LiDAR, drive an AlphaUni mobile mapping system or walk with an RS-series handheld SLAM scanner, CoPre reads the data directly and guides you to finished results in six steps.

Main features

Trajectory (POS) processing

CoPre computes the sensor trajectory with CHCNAV's own GNSS/IMU algorithm, then georeferences the LiDAR points and camera images. Several projects can be processed in parallel to save time.

Strip adjustment and control points

An advanced mode removes layering between overlapping strips and improves relative accuracy. Add ground control points to tighten absolute accuracy – CHCNAV quotes about 30% thinner point clouds than comparable products.

Colourisation, quality checks and reports

Colour point clouds from the onboard cameras, view datasets over 200 GB smoothly, check strips with automatic profiles, compare against elevation control points and export accuracy reports.

Orthophotos and 3D models

The reconstruction module runs aerial triangulation to create digital orthophoto maps (DOM) and 3D mesh models from the same flight – no extra software needed. Handheld SLAM data gets one-click optimisation, multi-station stitching and 3D modelling.

Coordinate systems for Canada

Choose from a worldwide coordinate system library or define your own projection and geoid. LATNET can set CoPre up for NAD83(CSRS), UTM / 3TM zones and the Canadian geoid models used in your province.

Supported CHCNAV LiDAR systems

• UAV LiDAR: AlphaAir series (AA450, AA6, AA9, AA10, AA15)
• Mobile and backpack LiDAR: AlphaUni series (AU20 and others)
• Handheld SLAM: RS series (RS7, RS10)

System requirements

CoPre licences are usually supplied with a CHCNAV LiDAR system. Contact LATNET for extra seats, upgrades or the airborne modelling module.
