Michael E Davias – LiDAR: Seeing the Earth in a New Light

When photography captures the Earth’s topography, vegetation often obfuscates the fine details. Light Detection and Ranging (LiDAR) allows the solid surface to be viewed in a new light. I have applied LiDAR technology to research the “Carolina bays”, ovoid basins found by the tens of thousands in the USA.

I have applied LiDAR technology to research the “Carolina bays”, ovoid basins found by the tens of thousands in the USA. The data is processed using a hue-saturation value table to present a false-color elevation map. To further enhance the 3-D topography, elevation values are exaggerated 20x and a “hill shade” algorithm is applied. The imagery documents how enigmatically “cookie cutter” they are. Often times I am blown away by their beauty.

………………..

Michael Davias is a retired computer scientist who is intrigued by the enigmatic Carolina bays. He has applied his computational and visualization skills to socializing their presence on the landscape to scientists across a broad range of interdisciplinary skills, and has presented numerous talks and posters at geological and planetary science meetings over the past 10 years. A web site containing more details is available at http://mptImpact.org. While not crafting a narrative for his geological avocation, he also dabbles in classic car restoration and gardening
