DEM - CONTOURS - FOCAL STATISTICS

Question

Hello All, I have generated a few different sets of contours (1m, 5m, .25m intervals) from a DEM I have of Christchurch city. With each interval tested above, the contours that result are very 'non cartographic'. I have tried simplifying & smoothing but would like a much more generalised outcome if possible. I also used the focal statistic operation on the DEM then generated contours from the outputted raster but the results were similar. Have I incorrectly used the focal statistic operation? Any suggestions / help appreciated! Thanks

Which neighborhood method is best used in this situation? Should I go with the default rectangle method and produce the contours out from the resulted raster ?

your contour interval is too fine to produce any meaningful representation at the view scale.  you might want to try a coarser interval (5, 10 m) as separate layers and assigning visibility through scale ranges.
