I have created a personal geodatabase which includes a baseline feature layer and a shoreline feature layer both in WGS84 coordinate system. DSAS casts transects in order to calculate shore erosion.

When I try to cast transects an error pops up saying:

Baseline layer is either not projected or the projection does not use metres as linear unit. Edit projection baseline

If you need units of measure to be in metres then you'll need a projected not a geographic coordinate reference system; so if you currently have EPSG:4326 you'll need to reproject your data, as EPSG:4326 has units of degrees.
