J-ATLAS, the Javalambre Andromeda and Triangulum Legacy Astrophysical Survey, is a proposed wide-field optical photospectroscopic survey of the M31--M33 system with JST/T250 and JPCam. Using the dense J-PAS filter system, it will deliver homogeneous low-resolution optical SEDs for resolved stars, compact stellar systems, emission-line sources, and background objects across the nearest massive spiral-galaxy environment visible from the northern sky.
