Perth Metropolitan LiDAR Capture Date Index

A 1km x 1km grid index detailing acquisition dates for LiDAR surveys over the Perth metropolitan area. The dataset, created by Landgate's Richard Nicholls, serves as a metadata reference for locating and requesting the actual LiDAR data, which must be obtained through a separate transaction form.

Use Cases

• Map the spatial distribution of LiDAR survey capture dates across the 1km grid cells to analyze acquisition phasing.
• Use the capture date index as a lookup table to determine the vintage of LiDAR data available for a specific 1km tile in Perth.
• Support project planning by identifying areas with recent LiDAR captures versus older surveys based on the date index.

Strengths

• Provides a systematic 1km x 1km grid index for the entire Perth metropolitan area.
• Authoritative provenance from Landgate, the Western Australian government's land information authority.
• Multiple accessible formats including GeoJSON, SHP, and Geopackage for GIS integration.

Limitations

• Contains only metadata (capture dates); the actual LiDAR point cloud or derivative products are not included.
• Access to the referenced LiDAR data requires a separate formal request process, not direct download.
• The dataset's utility is dependent on external data availability and licensing terms.
