# How to add an individual basemap or imagery layer from LINZ Basemaps to ArcGIS

1. Open LINZ Basemaps in a web browser.

2. Click on the `Menu` icon to reveal the sidebar.

3. From the `Layers` dropdown, select the desired layer.

   You can also type into the search box to filter down the list. Searching by a date or region can make it easier to find the layer you want.

4. Decide which map projection to work in (NZ Transverse Mercator or Web Mercator)

5. Copy the WMTS url eg https://basemaps.linz.govt.nz/v1/tiles/port-hills-false-colour-2024-10m/NZTM2000Quad/WMTSCapabilities.xml?api=[YourAPIKeyHere]

6. Open ArcGIS Online Web Viewer > Add layer > Add layer from URL > Paste WMTS URL from above

7. Remove from the end of the url ##?api=[YourAPIKeyHere]## This should automatically recognise the layer type as WMTS (OGC)

   - Add custom parameter

     - parameter = api
     - value = [YourAPIKeyHere] eg d01gbxm6mtx9ne1c09y8e6fwd9c (replace this example with your API key)

   - Add custom parameter

     - parameter = format
     - value = png

   Note: parameters and values must be lowercase

8. Next > Add to Map

Tip

If you create your own AGOL Item for each imagery layer and then share these with your own AGOL Group, it will make it easier to reuse the imagery again.
