LIDAR maps are some of the most futuristic-looking of all maps,
using remote sensing technology and reflected light (from a target illuminated
by a laser) to measure distances.
LIDAR maps are often used to show projections of an area in three
dimensions. In this LIDAR map of
San Francisco, we can see the flooding that is projected for the city in 2030
due to sea level rise. The
projection is distinguished from the actual photo of San Francisco today by a
green-blue color. Although the
projection may or may not be 100% accurate, the LIDAR technology is undoubtedly
fascinating and effective.
