A Hololens app made to visualize Antarctic data for the Lamont-Doherty Earth Observatory. This demo application shows off how AR can be used to visualize 3D data collected in polar regions. Using ROSETTA (https://www.ldeo.columbia.edu/res/pi/rosetta/) RADAR and LiDAR data we can intuitively visualize 3D features.
The initial view is of the entire Antarctica continent, using the Bedmap2 model (Fretwell et al. 2013) as a 3D basemap over which we can overlay geophysical data using standard polar stereographic coordinates. The user also has a tagalong menu with a slider bar to increase the vertical exaggeration, select the ROSETTA flight layer, and also select the Ross Ice Shelf sub-region for more detailed viewing.
This image shows the Ross Ice Shelf sub-region, overlain with the ROSETTA flight paths (red = radar+lidar, blue = radar only). Vertical radargrams can also be visualized here.
Tie-line T1060 contains a number of selectable boxes that allows the user to bring up localized LiDAR surfaces to show how the surface features affect the radar images.
This example of a LiDAR surface can also be vertically exaggerated to highlight surface features such as narrow crevasses and wider rifts.
The app is not yet available on the Microsoft Store, and the demo is not yet complete so hold tight on an appx file! To run this application:
- Download or Clone this repository
- Delete the 'App' folder
- In Unity, build the project again making a new 'App' folder
- Open the new VS solution in VS17
- Set 'Solution Configuration' to 'Release'; 'Solution Platform' to 'x86'; select 'Device' from the dropdown menu next to 'Solution Platform'
- Connect the HoloLens through USB
- Hit F5 to debug, or Ctrl+F5 to build and deploy without debugging
