Using PostGIS to determine DMA for a GeoHex

Decoding Nielsen DMA from GeoHex

  • Nielsen Designated Market Area (DMA) is a geographic region where the population can receive the same broadcasts (TV/Radio, Cable/Internet).

  • GeoHex is a world coordinate system expressed by hexagon of various sizes. It's often used in games due to its simple matching nature. It's also useful for proximity/coverage since a hexagon approximates a circular area.

This gist is an exercise in figuring out DMA from a geohex code using opensource tools and data.

How it works

Checkout github pull requests locally

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
