# TileMatrixSet

> **TileMatrixSet** = `object`

Defined in: [geo/projection/tile\_matrix\_set.ts:6](<https://github.com/maplibre/maplibre-gl-js/blob/638b3f9ecab4b743fd4d086d3bfd19bce7b7b032/src/geo/projection/tile_matrix_set.ts#L6>)

**`Experimental`**

A square, power-of-two quad tile matrix set laid over a planar CRS: tile 0/0/0 is the square of side `extentAtZoom0` whose top-left corner is `origin`, and every zoom level splits each tile in four.

## Properties

### extentAtZoom0

> **extentAtZoom0**: `number`

Defined in: [geo/projection/tile\_matrix\_set.ts:15](<https://github.com/maplibre/maplibre-gl-js/blob/638b3f9ecab4b743fd4d086d3bfd19bce7b7b032/src/geo/projection/tile_matrix_set.ts#L15>)

Width (= height) of tile 0/0/0 in CRS units.

### origin

> **origin**: \[`number`, `number`\]

Defined in: [geo/projection/tile\_matrix\_set.ts:11](<https://github.com/maplibre/maplibre-gl-js/blob/638b3f9ecab4b743fd4d086d3bfd19bce7b7b032/src/geo/projection/tile_matrix_set.ts#L11>)

CRS coordinates of the top-left corner of tile 0/0/0 (min x, max y); x and y are in the order the definition's `projection.forward` returns (easting, northing for a projected CRS).
