The focus here is on the determination of accurate and precise atmospheric parameters for a sample of 35 Galactic BA-type supergiants. Some first applications include a recalibration of functional relationships between spectral-type, intrinsic colours, bolometric corrections and effective temperature, and an exploration of the reddening-free Johnson Q and Str\\\"omgren [c_1] and beta-indices as photometric indicators for effective temperatures and gravities of BA-type supergiants.
