We present, for the planetary nebula NGC 2022, emission line flux mapping extracted from long-slit spectra taken with the 2.56 m Nordic Optical Telescope. Two-dimensional emission-line images for the entire nebula are created using data from only half of the nebula (which is symmetric), and are used to derive fluxes for 19 lines. We also create the Halpha/Hbeta extinction map, the [SII] and [Ar IV] line ratio density maps, and the [OIII] temperature map of the nebula. The total Hbeta flux is compared with values obtained by other authors. With these results we are now ready to begin modelling the nebula with a 3-D photoionization code, which will allow us to determine the 3-D structure, central star properties, and the distance to NGC 2022.
