Custom Raster Layer

URL Template for the tile server​

To display custom raster tiles as an overlay in Icon Map Pro you need to use the template XYZ template for the URL.

For example, to overlay OpenSeaMap navigation elements over the background map, we can use the following URL format:

https://t1.openseamap.org/seamark/{z}/{x}/{y}.png

This can also be provided using Power BI conditional formatting as a measure, to allow it to be dynamically modified.

Raster Layer

When using custom tiles, ensure that you also include any additional attribution required by the map provider. This can be added in the Controls formatting options.

Transparency​

Percentage transparency of the layer between 0 and 100.

Min Zoom​

The zoom level (0 = whole earth, 22 = street level) at which the layer will start to appear

Max Zoom​

The zoom level (0 = whole earth, 22 = street level) at which the layer will stop appearing

Visible​

This allows you to use conditional formatting to determine whether the layer is visible or not. Use a field or DAX measure that returns "yes" or "no" to determine whether the layer is shown or not.

Z-Index​

Position of the layer relative to other Icon Map Pro layers.

Additional Layers​

It is possible to overlay multiple custom raster layers on the same map.

Specify the number of additional layers using the "Number of Additional Layers" setting, then use the "Apply settings to" dropdown to configure the selected layer in the section below.
