Church Location Analysis

Public data used in blogger's analysis

I don’t pretend to have the technical knowledge to fully understand the analysis, but I was intrigued to find the Delaware DataMIL and New Castle County’s ParcelView cited as data sources on a blog post by The Honest Hypocrite yesterday.

In his post “Crypto-Catholics – Sun Worshippers at the Winter Solstice?“, blogger Richard, from Wilmington, analyzes the positioning of his church, Immaculate Heart of Mary Catholic church at  Shipley and Weldin Roads, to try to determine whether or not it is intentionally aligned with the sunrise at Winter Solstice.

    This is very cool. Transverse Mercator is a conformal projection, preserving direction, so moving to spherical geometry likely wouldn’t help much.

    Talk about a geographic perspective! I wish more people did this kind of off-the-cuff analysis. Very few people follow up on their thoughts like this. Unfortunately, it’s the public interpretation that may help or hurt any thoughtful or scientific analysis, regardless of any knowledge by the public commentators. For this case, I think the author does a good job of presenting the situation. Of course, it needs to be considered in the light of all his other writings but at first glance, I liked his post.
