If the problem still persists contact with us and attach the following data:


Use orthographic camera projection

Use perspective camera projection

View the cloud from the right side

View the cloud from the top side

View the cloud from the front side

Use fly controls to navigate the point cloud

Use cursor keys and AWSD to move the camera

Use earth controls to navigate the point cloud

Drag a point and move the mouse

Use orbit controls to navigate the point cloud

The camera orbit around the center of the point cloud

Reset the camera to view the whole point cloud

Clip the point cloud using a bounding box volume

  • E: translate the bounding box
  • R: scale the bounding box
  • T: rotate the bounding box
  • C: switch clipping mode

Clip by a polygon

Clip by a screen box

Remove all clippings in the screen

Get the position of a point of the cloud

Measure angles between segments over points

Measure linear distances between points

Measure an area over the point cloud

Draw a profile line over the point cloud

  • Press Ctrl key while drag the final point to change profile's width

Export all measurements in DXF file format

Rotate the point cloud along the Z axis

Remove all measures and profiles drawn over the point cloud



Impresive quality! what LiDAR system type, please.

Actually I dont know about the hardware but I'll find out. This is official data that the city of Helsinki has purchased and shares it as free to download at https://kartta.hel.fi/?setlanguage=en Some details about the scanning: Point density at nadir 40 points/m². Flight altitude 380 m above ground level.
