IML Critical Zone Observatory, Clear Creek Aug 2014 Lidar Survey (532 nm)

This dataset was collected using the Optech Aquarius ALTM, a hybrid laser mapping system which collects simultaneous land and shallow water-depth measurements using a beam wavelength of 532 nm. <br><br>This dataset was collected by NCALM for PI Dr. Praveen Kumar, University of Illinois. Clear Creek is part of the Intensively Managed Landscapes (ILM) Critical Zone Observatory (CZO). <br><br> The requested survey area consisted of two rectangles - called East and West - enclosing approximately 204 square kilometers along with their associated watercourse corridors. The West rectangle is located 35 km NW of Iowa City, Iowa and the East rectangle is located 10 km NW of the same city. <br><br>This survey was performed with 2 different LiDAR systems: 1) Optech Gemini Airborne Laser Terrain Mapper (ALTM) (available <a href=\"http://opentopo.sdsc.edu/lidarDataset?opentopoID=OTLAS.122016.26915.1\">here</a>) which is an infrared laser mapping sensor and 2) Optech Aquarius ALTM (this dataset) which is a hybrid laser mapping system as it collects simultaneous land and shallow water-depth measurements. It operates in the green spectrum, thus enabling it to penetrate water. These LiDAR mapping systems along with an Optech 12-bit full waveform digitizer were mounted consecutively in a twin-engine Piper PA- 31-350 Navajo Chieftain (Tail Number N154WW). <br><br>Full waveform files are available via <a href=\"https://cloud.sdsc.edu/v1/AUTH_opentopography/PC_Bulk/IA14_Kumar_Waveform/\">this link</a>.<p><br>Publications associated with this dataset can be found at <a href=\"http://calm.geo.berkeley.edu/ncalm/dtc.html\" target=\"_blank\">NCALM's Data Tracking Center</a></p>
