2019 Aerial Imagery Mosaic of Melbourne at 5cm Resolution

A 5cm pixel resolution RGB aerial mosaic of the City of Melbourne municipal area, captured on February 2nd and 3rd, 2019. The imagery was acquired using an 11-band multispectral camera system from 8,000ft under cloudless conditions. The primary data file is a 6GB georeferenced ECW image.

Use Cases

• Train semantic segmentation models on the high-resolution RGB mosaic for urban feature classification.
• Analyze vegetation health and condition using the underlying 4-band multispectral imagery co-registered to the RGB mosaic.
• Perform change detection against other temporal snapshots using the precisely georeferenced 5cm pixel imagery.
• Extract building footprints and property boundaries from the 'top down' view for urban planning applications.

Strengths

• Very high spatial resolution with a 5cm ground sample distance for the RGB mosaic.
• Imagery captured under optimal, cloudless conditions between 09:45 and 12:45.
• Includes co-registered 4-band multispectral data from a specialized 11-band camera system.
• Precisely georeferenced in MGA Zone 55 map projection.

Limitations

• Single temporal snapshot from early 2019, limiting analysis of changes over time.
• Large 6GB ECW file requires specialized GIS or remote sensing software to process.
• Coverage is limited to the City of Melbourne municipal area, not a broader region.
