Welcome Guest ( Sign In )

Overview

Data was collected in April 2019 for a repeat high resolution mapping of Antelope Valley, CA. Data was collected by NCALM for William Dietrich at the University of California. Approximately 24 km² of high resolution data were collected over Antelope Valley Ranch - 60 km west of Yuba City, CA.

Previous mapping of this area was done in 2017. For more details on the 2017 mapping project, click here
