 Data is organized into several thematic layers, each of which is named, for example; `buildings`, `pois`, and `water`. A selection of these layers are typically used for base map rendering, and are provided under the short-hand name `all`. Each layer includes a simplified view of OpenStreetMap data for easier consumption, with common tags often condensed into a single `kind` field as noted below.
