Problem with Jeranism is that he doesn't sound like the guy who studied physics or other technical disciplines. Thus lacking any experience in solving problems by providing adequate evidence and necessary proofs.
In this case, he could've started by using google earth to show locations and elevations. Autocad would be nice.

Reference to people who have no clue about the scientific method and no knowledge of the particular science they trying to disprove is a disservice to alternative researchers.
