NSW Imagery Date Web Service: Satellite and Aerial Imagery Footprints

A web service provides access to footprints for multiple imagery types covering New South Wales, Australia. It includes footprints for LANDSAT satellite imagery, standard 50cm orthorectified imagery, and high-resolution 10cm town imagery, plus other projects captured by AAM and Jacobs. The service is updated periodically when new imagery becomes available and is compliant with NSW FSDF specifications.

Use Cases

• Identify the most recent available imagery for a location based on the progressive overlay logic described.
• Plan new imagery acquisition by analyzing the extent and capture dates of existing standard and high-resolution imagery footprints.
• Assess temporal change by comparing imagery capture dates across different resolutions and sources within the repository.

Strengths

• Includes multiple imagery types (LANDSAT, 50cm orthorectified, 10cm town imagery) from sources like AAM and Jacobs.
• Service is updated periodically with new imagery, suggesting ongoing maintenance.
• Footprints provide an approximate imagery capture date and extent for all image categories.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The service is available in a cached environment only, which may limit access methods.
