Description: This dataset displays the land extent of the State of Queensland and comprises the state border (the cadastral boundary between the states) and the coastline of Queensland; including marine islands. The state border coincides with the position as shown in the Queensland Digital Cadastral Database, while the coastline is the boundary between the mainland, marine islands and the sea, and is generally defined as mean high water, except in the area of mangroves, where the coastline is depicted as the seaward edge of the mangroves. The coastline generally extends up estuaries to agree with the boundaries as depicted by the Queensland Drainage Basins dataset. The coastline has been compiled from the best available imagery and attributes within the data describe the source and age of the imagery. Source imagery includes: - Queensland Orthophotography- Satellite Imagery
