  We present maps of dust emission at 7 microns and 15 microns/7 microns
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.
