Recent simulation racing games such as iRacing, Assetto Corsa and Project CARS increasingly feature race tracks reproduced from 3 - D point clouds acquired through
Lidar surveys, resulting in surfaces replicated with millimeter precision in the in - game 3 - D environment.
«
LIDAR surveys are conducted at a much higher elevation, so they are not useful for the more subtle differences in vegetation elevation that higher - resolution, low - elevation drone surveys can provide,» explains Cruzan.
The high - resolution maps cover 3,564 square kilometers of the McMurdo Dry Valleys and allow researchers to compare present - day conditions with lower - resolution
LIDAR surveys conducted almost 13 years ago.
Fundraising is already taking place for a second
LiDAR survey of similar size, he said.
The LiDAR survey is a collaboration between archaeologists from the U.S., Europe and Guatemala, and the Fundación PACUNAM (Patrimonio Cultural y Natural Maya), a Guatemalan philanthropic and cultural heritage preservation organization.
