Recently i tried the google maps integration with report/document and here are my inputs and some defintions with the help of MicroStrategy

Main Features :

• Google Maps can viewed as regular maps
• Threshold can be used
• you can select single or multiple locations in the map and that can be used as filter

Prerequisites :

• Need to get a license from Google (Google Maps API)
• Configure the license with MicroStrategy WEB
• Login to MSTR WEb –> Preferences –> Project Defaults –> General –> under Custom Visualizations –> Enable Custom Visualizations Editor

To deploy the Map visualization plug-in to your MicroStrategy Web installation  and configure it, do the following:
