LIDAR is a technology where a scanner emits pulses of light energy (using a laser) at buildings and other objects in an area, and measures how long it takes for the pulse to return. The laser pulse travels at the speed of light. Accordingly, the distance it travels can be calculated by multiplying the amount of time it takes for the pulse to arrive back at the scanner, with the speed of light, and dividing that figure by two (since the pulse makes a round trip).
To toggle LIDAR on or off, navigate to your project and design, and click the LIDAR button:
You will now see a number of settings on the right side of the screen:
Choose whether to use the Aurora LIDAR imagery or Google 3D imagery (More information on sources at Where is LIDAR available in Aurora?):
Choose how you want to see the LIDAR data:
Toggle to change the LIDAR data coloration between irradiance and map imagery.
These tools allow you to move the LIDAR data points in order to line them up more accurately:
X - moves the LIDAR data points East and West
Y - moves the LIDAR data points North and South
Z - moves the LIDAR data points up and down vertically
How to Use LIDAR
- After completing your design, click on the LIDAR button on the top menu.
- Toggle into the 3D view by clicking the 3D box icon (or holding right click) and moving your cursor up.
- Click the LIDAR Settings button to toggle between Mesh or Point Cloud.
- Adjust the LIDAR data by using the x, y, and z coordinate fields.
- After calibrating LIDAR, click on the Fit Buildings to LIDAR button to fit your design to the LIDAR data. Or, manually adjust the height and pitch of your site model to match the LIDAR data.
