In 2021 a review of possible early definition surveys was completed by an Early-Definition Astrophysics Survey Assessment Committee. The committee found that there was sufficient justification to define an Early-Definition General Astrophysics Survey through a community-led process. 

The top-ranked concept was a survey of the Galactic Plane. Accordingly, a community-defined Roman Galactic Plane General Astrophysics Survey, of up to approximately 700 hours, has been defined by a committee of community members utilizing community input in an analogous method to the definition of Roman's Core Community Surveys by the Core Community Survey definition committees. 

There are no mission level science requirements on a Roman Galactic Plane Survey, leaving the full parameter space available to define the observational strategies (filters, depth, cadence, etc.) in a way that will enable a broad range of astrophysical investigations with Roman data of the Galactic Plane.
