Using views to display KML of each node in respective maps for each node
If I understand you correctly, your question is how to attach a view to a node.
You can check out the EVA module:


  "Eva" is short for "Entity Views Attachment;" it provides a Views
  display plugin that allows the output of a View to be attached to the
  content of any Drupal entity. The body of a node or comment, the
  profile of a user account, or the listing page for a Taxonomy term are
  all examples of entity content.
