A LITTLE MORE ON LIDAR
Lidar, an acronym for “light detection and ranging,” is a
means of measuring distance using laser pulses. It’s similar
to radar or sonar but uses an optical source – a laser –
instead of microwaves or sound waves. With lidar, a pulse

is fired from a sensor and a very accurate distance can be
calculated from the object it hits. (When you have a billion
measurements in a county, you can get a rather complex surface
model of the earth).
Lidar technology provides a combination of data density,
integrity, and accuracy that, in the past, was impractical to
achieve using traditional survey methods.
Ayres provides a complete lidar service – first deploying the
most appropriate technology, then calibrating clients’ datasets,
extracting the information needed to improve their operations,
and ultimately processing and providing a product tailored to the
client’s specific needs.
