Hi,
yes it's possible but it is not recommended.

if you have more than 200 users your site will become slow and it's possible that you have timeout problems.

It will be about 60 profiles.
Is it also possibel to make a selection frist and then show the map..

Is there an example where i can see this functionality

It will be about 60 profiles.

Is it also possibel to make a selection frist and then show the map..

Yes you can use "SQL custom where" parameter to filter for usergroups,custom fields, and complex query. docs at https://www.easy-profile.com/docs/69-sql-custom-where-list-and-module.html
