LiDAR stands for Light Detection and Ranging. By bouncing light waves off objects and structures, we can get a digital 3-D image of the ground and whatâ€™s on it. LiDAR can distinguish between earth, water, buildings, roads, trees, crops and countless other types of surfaces. This data is a fundamental building block of geographic information systems.
LiDAR has many benefits, including improved:
The statewide LiDAR point cloud dataset includes more than four terabytes of elevation data, consisting of billions of individual X,Y,Z data points precisely mapping the surface of Indiana. This elevation dataset is an extremely powerful tool that can support many projects across Indiana, but it can also be daunting to work with, especially when you only need a small area for your project and it needs to be in a usable format.
The solution is OpenTopography, a managed hosting service offered by the San Diego Supercomputer Center at UC San Diego. It allows anyone to easily access point cloud data online with no cost to the end-user. Anyone can go online, identify an area of interest on the map, and select the output product and format. The LiDAR Server then automatically clips, processes, zips and ships the dataset to the user.
IGIC Corporate or Institutional Members who would like copies of all or part of the 2011 data can also email Phil Worrall at email@example.com for information on checking out a hard drive.
Thanks to the generous support of our OpenTopography sponsors and supporters, the Indiana LiDAR and DEM data is available free of charge to the public on the OpenTopography Server!
