We present maps of dust emission at 7 $\mu$m and 15 $\mu$m/7 $\mu$m intensity ratios of selected regions in 43 spiral galaxies observed with ISOCAM. This atlas is a complement to studies based on these observations, dealing with star formation in centers of barred galaxies and in spiral disks. It is accompanied by a detailed description of data reduction and an inventory of generic morphological properties in groups defined according to bar strength and HI gas content.

Key words: atlas -- galaxies: spiral -- galaxies: ISM -- infrared: ISM: continuum -- infrared: ISM: lines and bands
