摘要：
Our panoramic imaging survey of M31 with the INT Wide-Field Camera currently maps an area of 25 squaredegrees around our nearest large galactic neighbour. We discuss evidence for spatial density and metallicity (as inferred from color) variations in the distribution of individual red giant branch stars in the halo and outer disk.
