The NSW Government is committed to providing fact based information about environmental factors in New South Wales. The Sharing and Enabling Environmental Data – SEED portal is designed to improve transparency by bringing together the best scientific data relating to land, water, biota and air.

SEED is a central source that is for anyone who wants to:

  • learn more about the environment in a local area
  • see the data that is being used to make decisions about the environment
  • access information that can assist with land management to ensure its long-term sustainability.

The SEED portal is easy to navigate and can be used without the need for specialist software or expertise and has a feature that allows you to create, save and print your own maps displaying only the information you require. It can help answer a simple individual enquiry about the environment or can be used for project planning purposes. For example, SEED can help with land management for farmers, development planning for councils, and impact assessments for environmental consultants.


More valuable data is being added to SEED as NSW Government agencies continue to work with the SEED portal custodians to upload information to the central database. In time, SEED aims to further expand the datasets by including reliable data supplied by industry, the community and environmental specialists.

Watch our short video that will show you the basics of SEED and how to navigate your way through the portal.

Environmental mapping for miners and explorers tool

We are improving customer service by introducing the Environmental Mapping for Miners and Explorers Tool (Environmental Mapping Tool). This new addition includes existing exploration and mining titles and most importantly helps bridge the critical link between environmentally sensitive areas and potential exploration and mining projects. The mapping facility allows you to create a user-friendly map in the Shared Enabling Environmental Data portal which can locate areas of environmental sensitivity within NSW so these areas can be accurately located throughout the planning stages for future mineral resources projects.

By using the Environmental Mapping Tool, miners and explorers are now able to define their application boundaries on a map and layer spatial information such as environmentally sensitive lands to validate and support their application. Being able to identify important environmental factors upfront, and avoiding environmentally sensitive areas, helps to streamline application and processing timeframes.

For example, the Environmental Mapping Tool can help explorers to avoid environmentally sensitive locations and plan impact mitigation. Should environmentally sensitive areas be avoided, and impact restrictions be adhered to, explorers will be able to apply for the Complying Exploration Activity (CEA) pathway for an exploration activity approval. A CEA has a 10 day assessment timeframe, compared to a 30 day assessment timeframe for Non-CEA projects.

The Environmental Mapping Tool can be used to:

  • interrogate and interpret data layers for environmentally sensitive lands
  • easily locate existing mining and exploration titles
  • plan exploration proposals by plotting points, drilling locations and calculating areas and distances
  • run a “Map Layer Intersection Report” to see where environmentally sensitive lands overlap on an existing mining or exploration title
  • create, save and print accurate maps that can be submitted with exploration activity applications
  • help explorers to comply with the Complying Exploration Activity (CEA) pathway for an exploration activity application.
