LIDAR Technology

LIDAR (Light Detection and Ranging) uses light to measure distances and can function underwater and on land.
Topographic LIDAR surveys use a near-infrared laser and require a setup including a laser, a scanner, and a platform-mounted GPS receiver.
The laser points at a target's surface, causing a reflection of light that is recorded by sensors to measure the distance traveled.

NAU Accessibility Mapping Project

A project at Northern Arizona University (NAU) uses LIDAR to improve surveying for an accessibility map of the campus.
The map will help determine the best routes for wheelchair users or people who want to avoid stairs.
The project relies on LIDAR, laser scanning, and drone-collected data.
The first phase will provide path-of-travel and slope specifics to viewers.
The second phase will create a version of the map to complement assistive technology tools, such as screen readers.

Impact on Surveying and Construction

The detailed map can guide future construction projects, revealing where accessibility efforts fall short.
It can ensure that all new buildings have accessibility requirements addressed from the start.
The evolution of surveying technologies is altering the ways surveyors work, reducing errors and repetitive tasks.
These improvements increase surveyor productivity and client satisfaction.
