The Sangamon River area is part of the Intensively Managed Landscapes (ILM) Critical Zone Observatory (CZO). <br><br> The requested survey area consisted of two connected rectangles enclosing approximately 198 square kilometers along with their associated watercourse corridors. The project rectangles are located 20 km west of Champaign. IL. The entire enclosed area of these 2 rectangles was surveyed with the Gemini (1064 nm, NIR instrument); the enclosed watercourse corridors illustrate where Aquarius (532 nm instrument) data was also collected.<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> National Center for Airborne Laser Mapping https://ncalm.cive.uh.edu/ originator National Science Foundation https://nsf.gov/ resourceProvider Intensively Managed Landscapes Critical Zone Observatory http://criticalzone.org/iml/ custodian null info@opentopography.org https://opentopography.org distributor en geoscientificInformation -88.6862243438149 -88.2705966765493 39.9748283314535 40.3101657391074 https://doi.org/10.5069/G9W66HQZ HTTP Standard Internet browser Download Navigate directly to the URL for data access and download.
