Long-slit spectra of high spectral and spatial resolution of the compa
ct planetary nebula Hu 2-1, are presented. The analysis of the [NII] 6
583 emission line detected in the spectra allows us to identify the ki
nematical components present in the nebula and to deduce their basic g
eometry. We use position-velocity maps of the [NII] 6583/H alpha line
intensity ratio in order to identify nebular regions in which shock-ex
citation and/or overabundace of N exist.
