Abstract. We have compiled a sample of galaxies with published catalogues of HII regions forming the basis for subsequent studies of the HII region distribution in spiral galaxies. As a first step we address the problem of the deprojection of a galaxy image as seen on the sky. We have devised two methods to do this, based on the HII region distributions themselves, and apply them to our sample. The results are compared with the ones obtained using several other methods and we find that our new methods are capable of obtaining good values for the position and inclination angles of the galaxies.
Key words: galaxies -- structure -- spiral galaxies --
interstellar medium : HII regions.
