The Big Bat LiDAR Project 2018

Lets start this with a giant thank you to the Cleveland Science Fund. Their generous grant covered everything but the toilets. They paid the equipment rental and the training. I stand in awe of the caver volunteers who work around the clock to collect this data. Cavers show up every year and do the most […]

The Natural Entrance to Big Bat Cave

The LiDAR point cloud data can be converted to imagery very easily.  This makes for much smaller files that are perfect for displaying the unique features in the cave.  The data does lose most of its analysis capabilities when it is converted to a raster but it is extremely useful to display features in the […]
