ABSTRACT: We used [NeII] line emission data (12.8 micron ), in order to investigate the detailed kinematic structure of the inner 3 * 4 pc of the Galaxy. The quality of [NeII] as a tracer of ionized gas is examined by comparing it to radio data. A three dimensional representation of the data cube allowed an exact distinction of the different features, which are reviewed in detail. A model of rotating gas in different plains is fitted to the data. Thus a classification of the different features could be made. It was found that most of them are situated together with the CND in the main plain. Finally we reconstructed the real three
