- Each successive bit of information provides additional accuracy so that the location of the point is gradually refined. This also allows the same formula to handle various levels of precision.
- The bits that represent latitude and longitude are interpolated with one another. That means that a single short piece of information represents the values in two dimensions. This is especially useful for matching and storing unique point values in a database
This is a two-way hash...a point can be encoded and decoded. There is a loss of precision...the final representation does not match the input value exactly, but is within a defined margin of error.
It looks much better than latitude and longitude values when passed in a URL, and it is easy enough to calculate that it is amost cost-free to use.
