Splataverse Maroochydore
Complete provider source scene, independently verified. Maroochydore, Sunshine Coast, Queensland, Australia: 66,714 finest textured source leaves, 21,128,009,080 balanced Gaussians, 4,224 archives (686.27 GB). Public dataset with manual access approval.
The provider scene envelope is approximately 56.8 km² (7.67 × 7.42 km), measured from the original EPSG:7856 XY bounding rectangle. This is a scene envelope, not occupied mesh area or municipal coverage. The source is real regional aerial photogrammetry.

Data
All converted payloads are here in shards/, using versionless paths. Each TAR has an exact JSON manifest listing source node IDs, Gaussian counts, coordinate transforms, archive hashes and source correspondence validation. Each outer TAR contains source-node TARs with chunked SPZ Gaussians, correspondence sidecars and retained original geometry, textures and node metadata. Documented SPZ-unrepresentable scales retain lossless Gaussian NPZ encoding.
Sampling uses the validated CPU balanced factor-2 city recipe, with no count truncation. Conversion and server-side copying preserve all frozen finest textured source leaves exactly once. Source metadata remain in the city index; byte-identical archive duplicates are removed there only after the dedicated copies are verified, avoiding permanent duplicate storage. Legacy Sunshine Coast HLOD and cropped-block releases are separate representations; their counts should not be added to this release.
Download
After requesting access and logging in with hf auth login, download individual source-linked shards rather than the full city at once:
hf download maxwildersmith/splataverse-maroochydore --repo-type dataset --include 'shards/task-000-part-000.*' --local-dir maroochydore
Read the adjacent JSON before loading a TAR. Node Gaussian coordinates are local meters; use each node's canonical_local_meters_to_source_projected transform for placement in EPSG:7856. Source triangle IDs, barycentric coordinates, UVs and source attributes are retained for ground-truth lifting.
Verification and provenance
The completion manifest checks every frozen source leaf without omissions, extras or duplicate IDs. Every archive's remote byte size and SHA-256 and every exact source JSON identity were checked at one pinned dedicated-repo commit. Each Gaussian's mesh position, source UV, texture color and physical scale were independently validated before publication. Appearance validation is the approved six-tile/twelve-view source-mesh pilot retained under validation/; this does not claim whole-city LPIPS certification or uniformly street-height capture.
A small number of unavailable preferred source resources were recovered using the same leaf's provider-authored DDS texture or Draco geometry. Native alternative bytes, metadata, decoded face-index mapping and explicit canonical-buffer provenance are retained inside the affected node TARs. No parent, sibling, alternative LOD or neighboring geometry was used. Decoder and independent source-control evidence.
