# Adding external layers Ellipsis Drive supports connecting external geospatial services directly into your maps. You can use external layers to visualise and combine data from third-party sources without importing or storing the data in your workspace. Supported service types include: * WMS * WMTS * XYZ * WFS * Vector Tiles *** #### Adding an external layer To connect an external service: 1. Go to **Layers** → **Browse** in the viewer sidebar 2. Under Base Layers, select **Add external layer** 3. Choose the service type 4. Enter or paste the service URL 5. Select the dataset from the service response 6. Provide a display name and confirm The layer is then added to your **base layers list** and can be added to your map view. #### Using external layers in your map Once added, external layers behave like standard map layers: * they can be toggled on and off * they can be combined with internal layers * they can be saved in bookmarks as part of a map view {% embed url="" %} #### Available external layer examples Below is a curated list of publicly available WMTS, WMS, and WFS services that can be used in Ellipsis Drive. These examples are provided for convenience and testing purposes. You can switch between WMTS, WMS, and WFS tabs to explore available datasets. {% tabs %} {% tab title="WMTS" %} #### **Country-Specific: The Netherlands** *Aerial imagery (very high resolution)* **Aerial Imagery 2020**\ url:[https://geodata.nationaalgeoregister.nl/luchtfoto/rgb/wmts/2016\_ortho25/EPSG:3857/{z}/{x}/{y}.jpeg](https://geodata.nationaalgeoregister.nl/luchtfoto/rgb/wmts/2016_ortho25/EPSG:3857/%7Bz%7D/%7Bx%7D/%7By%7D.jpeg)\ max zoom: 19 \ **Aerial Imagery 2019**\ url:[https://geodata.nationaalgeoregister.nl/luchtfoto/rgb/wmts/2019\_ortho25/EPSG:3857/{z}/{x}/{y}.jpeg](https://geodata.nationaalgeoregister.nl/luchtfoto/rgb/wmts/2019_ortho25/EPSG:3857/%7Bz%7D/%7Bx%7D/%7By%7D.jpeg)\ max zoom: 19 \ **Aerial Imagery 2018**\ url:[https://geodata.nationaalgeoregister.nl/luchtfoto/rgb/wmts/2018\_ortho25/EPSG:3857/{z}/{x}/{y}.jpeg](https://geodata.nationaalgeoregister.nl/luchtfoto/rgb/wmts/2018_ortho25/EPSG:3857/%7Bz%7D/%7Bx%7D/%7By%7D.jpeg)\ max zoom: 19 \ **Aerial Imagery 2017**\ url:[https://geodata.nationaalgeoregister.nl/luchtfoto/rgb/wmts/2017\_ortho25/EPSG:3857/{z}/{x}/{y}.jpeg](https://geodata.nationaalgeoregister.nl/luchtfoto/rgb/wmts/2017_ortho25/EPSG:3857/%7Bz%7D/%7Bx%7D/%7By%7D.jpeg)\ max zoom: 19 \ **Aerial Imagery 2016**\ url:[https://geodata.nationaalgeoregister.nl/luchtfoto/rgb/wmts/2016\_ortho25/EPSG:3857/{z}/{x}/{y}.jpeg](https://geodata.nationaalgeoregister.nl/luchtfoto/rgb/wmts/2016_ortho25/EPSG:3857/%7Bz%7D/%7Bx%7D/%7By%7D.jpeg)\ max zoom: 19 #### **Country-Specific: The Netherlands** *Land Administration* WMTS\ **National geo registry: BGT**\ url:[https://geodata.nationaalgeoregister.nl/tiles/service/wmts/brtachtergrondkaart/EPSG:3857/{z}/{x}/{y}.png](https://geodata.nationaalgeoregister.nl/tiles/service/wmts/brtachtergrondkaart/EPSG:3857/%7Bz%7D/%7Bx%7D/%7By%7D.png)\ maxZoom: 19 {% endtab %} {% tab title="WMS" %} #### **Soil Maps** **Soil Maps: Soil Classes Layer**\ URL: \ Legend url: \ **Soil Maps: Organic Content Layer**\ URL: \ Legend url: \ **Soil Maps: Clay Content Layer**\ URL: \ Legend url: \ **Soil Maps: Sand Content Layer**\ URL: \ Legend url: \ **Soil Maps: Coarse Content Layer**\ URL: \ Legend url: \ **Soil Maps: PH Layer**\ URL: \ Legend url: #### Country**-**Specific: USA **USGS: US Topo Map**\ URL: \ **USGS: US Hillshade Map** \ URL: \ **USGS: US Waterbodies Map**\ URL: #### **Country Specific: The Netherlands** *Satellite imagery (high resolution)* \ **Satellite data portal: September 2020**\ URL: \ **Satellite data portal: Augustus 2020**\ URL: \ **Satellite data portal: June 2020**\ URL: \ **Satellite data portal: May 2020**\ URL: **tellite data portal: December 2019**\ URL: \ **Satellite data portal: August 2019**\ URL: \ **Satellite data portal: June 2019**\ URL: , \ **Satellite data portal: May 2019**\ URL: \ **Satellite data portal: March 2019**\ URL: \ **Satellite data portal: September 2018**\ URL: \ **Satellite data portal: August 2018**\ URL: \ **Satellite data portal: June 2018**\ URL: \ **Satellite data portal: May 2018**\ URL: \ **Satellite data portal: March 2018**\ URL: \ **Satellite data portal: May 2018**\ URL: #### **Country Specific: The Netherlands** *Land Administration*\ \ **National geo registry: AHN**\ URL: {% endtab %} {% tab title="WFS" %} #### **Country Specific: The Netherlands** *Land Administration* **Vector Layers**\ \ **National geo registry: NAP Layer**\ URL: \ **National geo registry: Agricultural plots**\ URL: \ **National geo registry: Buildings**\ URL: \ **National geo registry: Cadastre**\ URLURL: {% endtab %} {% endtabs %} #### Contribute to this list If you know of additional open geospatial services that could be useful, you can suggest them for inclusion.
