This is useful for writing a map style. MapTiler Grid is a vector tileset providing global spatial reference layers, including international timezones, UTC offset boundaries, and a standardized WGS84 graticule. Explore the tileset in the interactive map viewer, check the date of the last update, use it as vector tiles, etc. [Go to MapTiler Grid](https://cloud.maptiler.com/tiles/grid/) ## Maps with this tileset [![Ocean map](https://cloud.maptiler.com/static/img/maps/ocean-v4.png) Ocean ](https://cloud.maptiler.com/maps/ocean-v4/)[![Ocean Dark map](https://cloud.maptiler.com/static/img/maps/ocean-v4-dark.png) Ocean Dark ](https://cloud.maptiler.com/maps/ocean-v4-dark/) ## Definition of layers The MapTiler Grid tileset contains the following layers: ## dateline [#](#dateline) Layer containing an established navigation boundary located near 180° longitude that serves as the globally recognized demarcation for the transition between calendar days. ### Fields #### name Name of the dateline.
