The download contains the populated data, a field dictionary, source metadata, reuse terms, a change log and file digests. It contains no scripts, libraries, executables or conversion tools.

## Coverage

Every geometry and feature in the Natural Earth 1:10 million lakes layer. Small water bodies are not exhaustively represented; polygons do not establish current water levels. Coordinates are WGS84 longitude, latitude.

## Read the data

JSON tables are arrays of records. GeoJSON files are FeatureCollections, with data fields under each feature’s properties. `data-dictionary.json` defines the fields, units, nulls and observed types. `metadata.json` supplies primary keys and source hashes. Preserve identifiers as text and distinguish missing values from zero.

GeoJSON coordinates are WGS84 in longitude, latitude order. Feature IDs are also present in properties.id.

## Example record

This is an actual record from the data. For map layers, the example shows properties; the downloaded GeoJSON also contains the complete geometry.
