I have file in Lambert Conformal conic format for the data of Australia, Its coordinates are in meters. I want to convert it to Latitude-Longitude format. Which Projection, Spheroid and Datum I should be using if I want to convert the projections in QGIS or Erdas Imagine?
The current Specification of the file is as follow: Projection: Lambert Conformal Conic Spheroid: GRS 1980 Datum: GDA94-ICSM Map Units: Meters
