# Raster Tile Layers

{% hint style="info" %}
A raster tile service is a web service that points to image tiles used in web maps, normally 256x256 pixel PNG or JPEG images stored in a Z/X/Y format. For example: <https://storage.googleapis.com/moabi-raster-tiles/LC81290522017025LGN00/{z}/{x}/{y}.png> is the link to a tiles for a Landsat 8 scene used in this layer in Map for Environment <https://mapforenvironment.org/layer/info/640/#10.22/11.853/99.5299>

{% hint style="warning" %}
Before you start you must have a [MapHubs account](/getting-started/signup-for-a-maphubs-account.md), and have a [group](/getting-started/groups.md) where you want to create the new layer
{% endhint %}

## Create a Layer

Create a new layer by going to the Explore -> Layers page and clicking the  + button in the bottom right. Alternative you can click the Add a Layer button from the page of a group, and some MapHubs portals will have a Create a Layer shortcut on the landing page.

Choose the *Raster Tiles* option

Enter the tile URL for the raster tile service, pay special attention to the template portion  of the URL which must have the `/{z}/{x}/{y}` coordinates.

{% hint style="info" %}
If you know the min and max zoom levels you can optionally configure them here. Setting the max zoom level (if known) will prevent a raster layer from disappearing in the map when you zoom in past its maximum
{% endhint %}

Next give the layer a name, description, source, and license. Choose the group where you want to save the layer.&#x20;

Finally zoom the preview map to the location of the raster data and optionally choose an opacity value for the layer if you want it to be transparent
