  We present filamentary structure analysis based on the CARMA Orion Project
through which we obtained high resolution (0.01pc) and high dynamic range
(2~deg in DEC) images of the Orion A molecular cloud. We show a preliminary
emission map of the $^{13}$CO emission with the addition of identified
filaments. The data product resulted from 1500~hr of observing time at CARMA
interferometer, and the Nobeyama 45~m telescope. We address basic filament
properties along with calculated typical kinematical properties. Furthermore,
we present a pilot study where we compare the observed [C{\sc II}] and [C{\sc
I}] emission to $^{13}$CO emission towards 6 selected filaments in Orion~A.
