# Tile Layer

{% hint style="info" %}
This page (and subpages) only talks about WMTS-supporting raster layers, which is the most common and default type of mapping.

For information about WMS-supporting layers or vector tiles, visit the [WMS Usage](/v3/usage/layers/wms-usage.md) page.
{% endhint %}

A tile layer displays raster map tiles in a grid pattern, from a tile source such as a remote server or file system. This might look something like this:

```dart
FlutterMap(
    options: MapOptions(),
    children: [
        TileLayer(
          urlTemplate: "https://tile.openstreetmap.org/{z}/{x}/{y}.png",
          userAgentPackageName: 'dev.fleaflet.flutter_map.example',
        ),
    ],
),
```

{% hint style="danger" %}
You must comply to your tile server's ToS. Failure to do so may result in you being banned from their services.

The OpenStreetMap Tile Server (as used above) can be [found here](https://operations.osmfoundation.org/policies/tiles). Other servers may have different terms.

This package is not responsible for your misuse of another tile server.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.fleaflet.dev/v3/usage/layers/tile-layer.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
