Distance in a map to a non-fixed point.

[AlbLS]

Hi everyone,

I hope you could help me.

I have a dataset with a list of clients with their latitude and longitude.

I have created a map where I can show customers who are at a distance (in kilometers) from a specific point.

What I would like is, to be able to choose a client in a slicer. And then be able to show the clients who are at a chosen distance from him.

The formula for calculating the distance is as follows:

KLM: = 
ACOS (
    COS ( RADIANS ( 90 - 'clients_test'[lat_origine] ) )
        * COS ( RADIANS ( 90 - 'clients_test'[latitude] ) )
        + SIN ( RADIANS ( 90 - 'clients_test'[lat_origine] ) )
            * SIN ( RADIANS ( 90 - 'clients_test'[latitude] ) )
            * COS ( RADIANS ( 'clients_test'[long_origine] - 'clients_test'[longitude] ))
) * 6371

Currently, I put the latitude and longitude in a column. What I want is that those two data come from a variable or a measure.

I leave you my power bi file HERE

Thank you very much in advance.

You may try SELECTEDVALUE to add a measure.

Hello @v-chuncz-msft ,

Thank you very much for your answer.

Could you explain a little more in detail what you mean, please?

I need to select a client in a slicer. Then, choose a distance to that client and that only the clients that are at the chosen distance of the first client are shown on the map.

How do I have to use the SELECTVALUE formula?

Thank you
