The process for obtaining Map data through JDBCTemplate.queryForMap involves the following steps:

1. Create an instance of JDBCTemplate class.
2. Write a SQL query to extract data from the database.
3. Call the JDBCTemplate.queryForMap method with the SQL query and necessary parameters.
4. The result will be a Map containing key-value pairs where the key represents the column name and the value represents the column value for each row.
5. Iterate through the Map to extract the required data.
