In July 1939 'Instructions for War – Survey' were issued. This outlined the military survey organisation required to undertake an Emergency Mapping Programme to complete the outstanding Long Range Mapping Programme and be the nucleus for expansion to war establishment. The Emergency Mapping Programme was initially for strategic mapping at scale eight-miles-to-one-inch of inland Australia, four-miles-to-one-inch ('four-mile maps') covering a coastal strip 200 miles (300 km) inland from Townsville to Port Augusta and 100 miles (200 km) inland from Albany to Geraldton and key strategic areas in Tasmania and around Darwin and 'one-mile' maps of populated places. Map production was from existing State Lands Department's information and conducted jointly between State Lands Departments and Survey Corps units. The programme expanded to include more of Australia, New Guinea, New Britain and New Ireland and although many maps were of a preliminary standard only, providing general coverage critical at the time.
