  Hierarchical galaxy formation models predict the development of elliptical
galaxies through a combination of the mergers and interactions of smaller
galaxies. We are carrying out a study of Early-Type Galaxies (ETGs) using GAMA
multi-wavelength and Herschel-ATLAS sub- mm data to understand their intrinsic
dust properties. The dust in some ETGs may be a relic of past interactions and
mergers of galaxies, or may be produced within the galaxies themselves. With
this large dataset we will probe the properties of the dust and its relation to
host galaxy properties. This paper presents our criteria for selecting ETGs and
explores the usefulness of proxies for their morphology, including optical
colour, Sersic index and Concentration index. We find that a combination of
criteria including r band Concentration index, ellipticity and apparent sizes
is needed to select a robust sample. Optical and sub-mm parameter diagnostics
are examined for the selected ETG sample, and the sub-mm data are fitted with
modified Planck functions giving initial estimates for the cold dust
temperatures and masses.
