Whilst Directories list service information, Atlases present the information visually using Geographical Information Systems (GIS). Both are decision support tools which support evidence-informed policy and planning. These tools account for local factors, highlight variations in care (including disparities in service access), and gaps in service provision. They make it easier to compare services across a number of health service areas.

Integrated atlases of care are built using a standardised taxonomy which allows comparisons between different geo-demographic areas. They provide a unique picture of the services provided by Primary Health Networks (PHNs) to individuals with a lived experience of mental illness. Services include residential care, outpatient care, facilitating accessibility to care for patients with long term care needs, facilities that provide patients with information and/or assessment of their needs, and self-help and voluntary care. They map services provided by the public health sector, non-governmental organisations (NGOs), family and community services (FACs), and the justice system.

Current Australian Atlases map areas covering almost 50% of the Australia鈥檚 population.
