We present line-strength maps of a sample of 18 late-type spirals. The data have been taken using SAURON at the WHT. Apart from the maps, we present the central line indices, and estimate the star formation time-scale. In an exponentially declining SFR scenario, we find a trend between the time-scale and the velocity dispersion: more massive galaxies show shorter burst durations. This result is in agreement with the analysis of H emission in galaxies. A detailed study on these data will be published by Ganda et al. (2007).
