INTRODUCTIONThe goal: The NASA GSFC VR/AR team created the LandscapesVRproject for geoscientists to view and analyze LiDAR data of a lava tube inan immersive 3D environment.

The problem: Nothing will ever replace field work, but viewing 3D infor-mation on a 2D screen does not always reveal the complexity, scale, andspatial relationships of geologic terrains. Recall of observations from afield site can also become fuzzy over time.

The solution: Virtual Reality (VR) allows geoscientists to view data froma boots-on-the-ground perspective, but also manipulate the environmentto achieve views unobtainable in the field.

The benefit: Geoscientists can revisit remote locations from a first-person perspective, explore sites they may have missed due to time con-straints or bad weather, and collaborate remotely from the office.

VR has rapidly become a more accessible, low-cost technology that cannow be developed and used by a broader user base.Field Site: Indian Tunnel Lava Tube at Craters of the Moon NationalMonument in IdahoData: Pointclouds are from Riegl VZ-400 lidar scans

DATA & TOOLS

The full pointcloud for the Indian Tunnel lava tube is ~900 million points.Limitations: We could only import a ~22 million points into a single VRscene. This is equivalent to a single lidar scan.

Import Text File: Lidar scans were exported as a text file with xyz rgb µand imported into Unity using a customized script.

Viewing Data: Users can view the points as natural (RGB), elevation, andreflectance.

We developed a series of preliminary tools to analyze the data.Draw Tool: Freeform line tool to circle or trace features.

Ruler Tool: Measure straight line or curved distance. Labels distance.

Waypoint Tool: Mark a point of interest.

Notes Tool: Write down information for a location

Eraser Tool: Deletes lines and waypoints.

Cost-effective: Low-cost, unique way to revisit field sites

User Controls: Still testing new ways to move through scenes, marklines and points, and export data and observations.

Limitations of VR software: Unity was user friendly, but not able tohandle the large amount of point data. OpenSceneGraph Earth can han-dle the large data sets, but we need to develop the geologic tools.
