WebTrak Addendum to SMO Analysis – January 2011

This document uses the data, particularly the observed flight paths, from the January 2011 study to compare with the tracks shown on the LAX WebTrak site in order to determine WebTrak accuracy. SMO later installed a WebTrak site of their own which contains identical data to the LAX site (since it uses the same LAX radar data). The accuracy conclusions in this document apply equally to the SMO WebTrak site.
