Precise geographic data is invaluable when it comes to software that has to know either where the hardware its running on is, or where something else is. And it seems that this particular type of data is found in software everywhere. And if it isn't, you could probably find a valid use case after browsing the code for ten minutes. Phenomenons hit software development culture, some stay while some disappear. The ones that stay, generally never stop evolving in an effort to standardize their meaning. Everyone must be on the same page, otherwise, you might as well create your own ad-hoc formulation. Geo is different. The way we store, manipulate, and use the data is constantly in flux. But the data itself — longitude and latitude — unchanging, and unambiguous.
