Use distance to filter?

I have two tables in Power BI desktop called 'Centers' and 'Stores'. The 'Centers' table contains only my shopping center locations and has the columns: [CenterID], [CenterLatitude], and [CenterLongitude]. The 'Stores' table contains store locations and has the columns: [StoreID], [StoreLatitude], [StoreLongitude], and [CenterID].  The 'Centers' table has a one-to-many relationship with the 'Stores' table.  Some of the stores in the 'Stores' table are located within my shopping center and will have a matching value in the [CenterID] column.  The stores that have a null value in the [CenterID] column are not within my shopping centers.  I want to be able to select a shopping center location and show all of the store locations that are within X miles or less of my shopping center location including my stores.  How can I do this?

    hi JoeMar ,

     

    you can calculate the perpendicular distance between two points, mentioned in the post below:

    Solved: Distance Calculation in Power BI - Microsoft Fabric Community

     

    You need Latitude and Longitude to calculate the distance between two locations with following formula:

 

=acos(sin(lat1)*sin(lat2)+cos(lat1)*cos(lat2)*cos(lon2-lon1))*6371

 

ps: 6371 is Earth radius in km.

 

You can achieve it via either Power Query or DAX method.

 

Or you can use Google Map API as @cs_skit suggested.

     

     

    i think you could filter by this distance column to get stores in proximity ( after selecting a point)
