I am using NASA's ISIS software to get data from their Planetary Data System. I have already created a base map using the Proj4 projection 4326. But i am not sure how to convert an ISIS simpleCylindrical projection (units in meters) to a Proj4 projection (units in decimal degrees).

Thanks,

Proj4:
<4326> +proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs  <>
