国のインフラ（ガスおよび電力ネットワーク、道路、鉄道など）をカバーするレイヤーを含む特徴データセットと、人口を詳細に示すLandscanデータがある場合、重要なインフラノード（つまり、オフラインになると最も多くの人口に影響を与えるノード）を特定するために使用できるツールや技術をご存知の方はいらっしゃいますか？<\/P>

これは災害対応準備の一環として調査しています。<\/P>

Hi Anthony,

More than providing a straight answer, I have an idea as to a process that may help you find an answer. What you're really asking for is a measure of centrality. There are many different ways to quantify aspects of centrality. Here is a quick primer on some of the more common measures and the math behind them. Perhaps this will give you a place to start. I am a criminologist/consulting detective. I use these measures to determine who in a network of criminals is more important to the overall functioning of their group. There's an incredible Excel template called NodeXL that might help you.

I know all this is pretty roundabout, but maybe it will spur your thinking.

Best,

Matthew
