Crews with San Francisco Public Works were out conducting the most complete survey yet of Market Street ahead of a major improvement project.

A truck was out there early Saturday morning, gathering information to create a 3D survey of the busy thoroughfare.

It used Light Detection and Ranging technology, or LIDAR for short.

This visual mapping survey is the first step to doing detailed design work for the Better Market Street Project and improve the transit and pedestrian-friendly corridor.

The technology picks up on every detail, including buildings, light poles, sidewalks and other street features.
