We discussed four different methods - the single, double and triple Gaussian fits, and the intensity weighted centroid fit - which extract rotation curves from several emis-sion lines(i.e. [OII], $H{eta}$, [OIII], and $H{alpha}$) of spiral galaxies. Spatial extents and the shapes of rotation curves derived through various methods applying to each emission lines of a sample galaxy UGC 11635 are all in a good agreement with one another. Linewidths of $H{eta}$ and $H{alpha}$ measure from rotation profiles are in a good agreement with $H{alpha}$ linewidth of Courteau (1992). however, linewidths of [OII] seems to be much broader than $H{alpha}$, and the profile of [OIII] does not follow the profile of $H{alpha}$.
