LakeATLAS v1.0 — global lake attributes and pour points

LakeATLAS lake polygons and pour points with hydro-environmental attributes in separate spatially ordered GeoParquet files, with a versioned field-semantics supplement. Separately versioned PMTiles provide map display for both layers and source-ID attribute lookup.

Validated hosted release: lakeatlas-v1.0-r2. The canonical record binds the public Source Cooperative package and its completed hosting checks.

Scope and formats

Two analytic GeoParquet assets from the pinned LakeATLAS v1.0 producer File Geodatabase: the complete polygon layer and separate pour-point layer. The deterministic spatially ordered representations preserve producer OBJECTID, Hylak_id and all decoded source fields, nulls, and WKB; WGS84 bbox fields support spatial filtering. No geometries are repaired or simplified. Attribute years vary by source and do not represent a 2026 observation.

Formats: application/json, application/pdf, application/vnd.apache.parquet, application/vnd.pmtiles, image/png, text/markdown.

Limitations

• Polygons and pour points are distinct producer layers, each retained separately.
• Attribute codes, scaling, spatial extent and aggregation rules must be interpreted using the versioned field-semantics supplement and producer documentation.
• The metadata supplement is separate from the unchanged immutable r2 analytical package.
• Live GEE counts and 522 sampled IDs per layer match. Both layers have numeric differences including integral GEE GDP values; the polygon layer also has three narrow source spikes absent spatially from GEE. Strict parity fails. No exhaustive GEE or independent scientific-accuracy claim.

Public hosting checks are bound in the canonical report. Scientific validation retains its documented scope.
