Re: [Linux-aus] Microsoft files new patent (another episode in your favourite "stupid patent" series)

I know that I did this for lat/longs (and a bunch of other data types using base-64) in 1983 (yes >20 years ago) in order to send data over primitive comms links that didn't like non-printable characters.

I can't imagine I was alone.

Methods are disclosed for encoding latitude/longitude coordinates within a URL in a relatively compact form. The method includes converting latitude and longitude coordinates from floating-point numbers to non-negative integers. A set of base-N string representations are generated for the integers (N represents the number of characters in an implementation-defined character set being utilized). The latitude string and longitude string are then concatenated to yield a single output string. The output string is utilized as a geographic indicator with a URL.
