Providers like Planet, Maxar, and the European Space Agency (ESA) offer a range of satellite imagery products with varying resolutions and spectral characteristics.
Aerial Imagery: Aerial imagery, captured from aircraft, offers higher resolution than satellite imagery and is used for applications such as urban planning, infrastructure mapping, and environmental assessment. Companies like Nearmap and Aerometrex specialise in capturing and processing aerial imagery.
LiDAR Data: LiDAR (Light Detection and Ranging) data provides highly accurate three-dimensional representations of the Earth's surface. It is used for applications such as terrain modelling, forestry management, and infrastructure mapping. LiDAR data is often collected by government agencies and private companies.
Cadastral Data: Cadastral data describes the boundaries of land parcels and is essential for property management, land administration, and urban planning. State land information agencies are the primary providers of cadastral data in Australia.
Topographic Data: Topographic data describes the physical features of the Earth's surface, including elevation, rivers, and vegetation. Geoscience Australia and state land information agencies provide topographic maps and digital elevation models (DEMs).
GPS Data: GPS (Global Positioning System) data provides accurate location information and is used for navigation, surveying, and location-based services. GPS data is collected by a variety of sources, including smartphones, GPS devices, and surveying equipment.
Open Data Sources: Increasing amounts of geospatial data are being made available as open data by government agencies and other organisations. These datasets are often free to use and can be a valuable resource for a wide range of applications. Check with your local council or state government to see what open data is available.
Understanding the characteristics and limitations of different data sources is crucial for selecting the most appropriate data for your application. Consider factors such as resolution, accuracy, coverage, and cost when choosing a data source.
3. Regulatory Frameworks for Geospatial Data
The use and management of geospatial data in Australia are governed by a range of regulatory frameworks. These frameworks address issues such as data privacy, intellectual property, and data quality.
Privacy Legislation: The Australian Privacy Principles (APPs), established under the Privacy Act 1988, regulate the collection, use, and disclosure of personal information, including location data. Organisations that collect location data must comply with the APPs.
Intellectual Property Rights: Copyright and other intellectual property rights may apply to geospatial data. Users must ensure that they have the necessary licences or permissions to use geospatial data.
Data Quality Standards: Various standards and guidelines address the quality of geospatial data. These standards aim to ensure that geospatial data is accurate, reliable, and fit for purpose. For example, the ANZLIC Spatial Data Management Guidelines provide guidance on managing spatial data.
