Workshops on Wednesdays

The 13th of February we will start with the first workshop for this semester. Previously we called this open-lab, but now we prefer to call it workshops. The idea with the workshops is start at 13:00 with a short introductory presentation of a remote sensing topic, for example use of drones in forestry. The presentation is 15-20 minutes long and after this the lab is open for you to hands on experiment and work with remote sensing data. We will always supply data for you to experiment with, but you can of course bring your own. Or use the labs equipment to collect new data. The lab closes at 15:00.

The topic for this first workshop is airborne laser scanning.

Beta release of PointCloud XR – A free viewer for point clouds in Virtual Reality

Today we release the first beta version of our application to view and analyze point clouds in Virtual Reality. We have named the application PointCloud XR and you can read more about the development and download PointCloud XR. Please add a comment on our Facebook page about your thoughts after you have tried it!

In the current version (2018-12-14) you can do the following:

  • Open points in LAS 1.2 format.
  • Depending on your hardware you can open about 15 million points and move around fluently.
  • You can “fly” around in the point cloud using your hand controller.
  • Change the size of the points.
  • Color the points by RGB, Class, Height or Intensity. The intensity can alway be blended with either of the other coloring modes.
  • Measure distance. You can snap to points and restrict measurement in y-direction or in the xz-plane.
  • Select points using a sphere. The selected points can the be removed.
  • Save the edited point cloud in PCXR-format. LAS exporter is not implemented yet but we are working on that.
  • Set a new start position. This will only work with a file saved in PCXR-format.
  • Change the throttle (how fast you are flying when you press the trigger).

Here is a clip when a few students try an earlier version of the application.



We have several different cameras that can be used either from air (drone) or from the ground. These are the available cameras:

Sony QX1. This camera is mounted in a gimbal and mounted to the lab’s 3DR Solo drone.

Thermal camera

The lab has a Flir Vue Pro 13mm thermal camera with 640×480 pixels resolution and 30 frames per second. The camera can be used to locate hot-spots when putting out a forest fire.

Here is an example of a flight in a prescribed fire in Ekträsk.

3DR Solo, equipped with Flir Vue and GoPro over prescribed fire.
