blog post content via url parameters (meta) in wordpress

Question

i am trying to create an url which will set the blog post like ./wp-admin/post-new.php?post_title=title

i know that post_title, content and excerpt will work for this, but i dont know how to set meta tags.

i need this to create a new posting when clicking on a map (openlayers) and automaticaly set longitude and latitude in meta tags.

I suppose, for auto-post-creating, you should dig XML-RPC interface first. This tool is not so hard to master and is very powerful.
