Lidar (also written LIDAR, LiDAR or LADAR) is a surveying technology that measures distance by illuminating a target with a laser light. Although thought by some to be an acronym of Light Detection And Ranging, the term lidar was actually created as a portmanteau of "light" and "radar". Lidar is popularly used as a technology to make high-resolution maps, with applications in geodesy, geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, atmospheric physics, airborne laser swath mapping (ALSM) and laser altimetry. What is known as Lidar is sometimes simply referred to as laser scanning or 3D scanning, with terrestrial, airborne and mobile applications.
Lidar originated in the early 1960s, shortly after the invention of the laser, and combined laser-focused imaging with radar's ability to calculate distances by measuring the time for a signal to return. Its first applications came in meteorology, where the National Center for Atmospheric Research used it to measure clouds. The general public became aware of the accuracy and usefulness of lidar systems in 1971 during the Apollo 15 mission, when astronauts used a laser altimeter to map the surface of the moon.
"Johnny, uh, some kids on the show yesterday mentioned a new kind of music - Ska. You know anything about it?" "Nothing but a modern off-shoot of Reggae, updated by rock influences. Deafeningly upbeat. Can never become really popular because even though they've made the back-beat more conventional, it's still too exotic for man's acceptance."
Hello, hey now
The Fonz is cool, Fonzy don't cry
Hello, hey now
Well ask Mr. T, he's a really nice guy
There we go with a sign of a smile
Slap in the goonies, we're lost for a while
Where'd you go my breakfast club girl?
Will you stand by me in a stand by World?
(Will you stand by me in a stand by World?
Will you stand by me? Oh yeah)
Hello, hey now
The Fonz is cool, Fonzy don't cry
Hello, hey now
Well ask Mr. T, he's a really nice guy
There we go with a sign of a smile
Slap in the Ferris, we're cool for a while
They sit like a diamond inside of me
In one
A portable vacuum
In two
A mini-bar
In three
A holiday weekend
In four a Jaguar
In five
A soda stream machine
In six
A Betamax
In seven
A Remington shaver
Once you try it you'll never go back
Well look at me
Look at me
Look at me
Look at me
About to fall apart
Yes I'm even empty-handed with my bulls-eye dart
Taking it back to summer of '85
Piggyback fights I was so
Alive
Will I find
Boba Fett?
And maybe my old Lego playset
Ip dip dog shit
You're on my friend
Cos you trod in it
Turkey Lurkey one, two, three
Tic off ground and it's home for tea
In one
A portable vacuum
In two
A mini-bar
In three
A holiday weekend
In four a Jaguar
In five
A soda stream machine
In six
A Betamax
In seven
A Remington shaver
Once you try it you'll never go back
Well look at me
Look at me
Look at me
Look at me
About to fall apart
Yes I'm even empty-handed with my bulls-eye dart
Well look at me
Look at me
Look at me
Look at me
About to fall apart
Yes I'm even empty-handed with my bulls-eye dart
