This repository contains the data gathered from a LIDAR based mapping system as well as a program that can be used to view the data in an interactive manner. The system was placed in numerous locations and scans were taken with a resolution of 1 degree at various fields of view. This repository is intended for anyone interested in personally viewing the data collected.
The data can be viewed in a video form on youtube: https://www.youtube.com/watch?v=IuVW84EPHkI
The system used to gather this data was designed and built by Dustin Wagner and Darienne Johnson. For more information on how this system gathered data and how you could build your own system, please contact Dustin Wagner on discord at:

Project is provided as source code for maximum compatibility with all operating systems. The following instructions describe how to download and use everything needed to interact with the data collected.
This includes downloading 2 pieces of software: The first is the Godot game engine used to run our program. The second is the the lidardata program that we have created. This will be downloaded as a Zip file from this page.
Download the standard version, 64 bit Godot game engine for your specific operating system from their website https://godotengine.org/download
The game engine is self contained and does not require installation
Download the ZIP file of this lidardata repository from GitHub as in the following picture or by clicking the following link:
https://github.com/wagnerd97/lidardata/archive/refs/heads/main.zip
Un-ZIP the repository and note the location
Launch Godot
Note: on Mac OS the message "Can't be opened because it is from an unidentified developer" may prevent the use of Godot
To bypass this follow these steps:
- Open your computer system preferences > Security & Privacy > General
- Here you should see an option to "Allow Anyway" next to the Godot application
This may vary between different versions of iOS
press the import button
press browse to open a file explorer
navigate to the lidardata folder we un-ZIPed in step 3
within the lidardata folder navigate into the LIDARDisplay folder
within the LIDARDisplay folder select and open the project.godot file
Press the "Import & Edit" button
Godot should open. when it does you can launch the program by pressing the play button in the top right corner of the screen
When the program loads, it will open a Godot file explorer. On Windows this file explorer should open to the folder "ScansAndPictures". On Mac OS, The folder that opens may be "LIDARDisplay". in this case navigate up
Then navigate into the "ScansAndPictures" folder
From this folder select any available .dat file and an animation will begin that draws the image at ~2x the speed it was gathered at. (This can be skipped by pressing Enter)
If you would like to compare the scan to a photogrpahed image of the space it represents then:
- Open a file explorer
- navigate to the "ScansAndPictures" folder
- open the corresponding .jpg file in a photo viewing application
