Multiple Analysis in ArcGIS Maps

Hi Pojha - Yes, it is possible to achieve a multi-layer analysis in ArcGIS Maps for Power BI to display different drive times (e.g., 20-minute and 30-minute) and to use color coding for easier analysis of overlapping areas. 

You can create multiple drive-time layers by following these steps:

Enable the ArcGIS Visual in Power BI:

Add the ArcGIS Maps visual from the visualization pane.
Add Data Points:

Ensure your dataset includes the locations for which you want to calculate drive times.
Create Multiple Drive-Time Buffers:

Use the Drive-Time Analysis tool in ArcGIS Maps:
Open the Layers menu.
Select your locations and apply a drive-time area. Specify a 20-minute buffer for one layer.
Repeat the process for a 30-minute drive-time buffer in another layer.
Differentiate Layers:

Assign a unique name and description to each layer for clarity.

Go to the Layer Settings in the ArcGIS visual.
Select the layer representing the 20-minute drive time, and assign a distinct color (e.g., blue).
Repeat for the 30-minute drive-time layer with a different color (e.g., orange).
Adjust Transparency:

In the Layer Settings, adjust the transparency of each layer to see overlapping regions.
