The Universal Property Identifier System
|
The Natural Area Coding System has also produced an ideal property identifier
system called the Universal Property Identifier (UPID) System. A UPID is an eight or
ten-character Universal Address representing a 0.8 x 1.6 meters or 25 x 34 meters
reference area of a property defined by the owner of the property. The UPID for
a unit in a building can be constructed using the Universal Address of the building
plus a unit number such as: 8CNJ Q8ZJ U1608.
The advantages of the system are:
- the UPID can be directly displayed and navigated with GPS without any database support;
- when they are displayed on a cellphone real-estate application, a UPID will not only
identify the property, but also tells exactly where it is, which can avoid many unnecessary
requests for location information from a server;
- since street address databases do not include new house addresses, the UPID can play
a unique role to specify these locations on driving directions services such as:

- the UPID is permanently attached to the property and never change, which can
save a lot of work when the political boundary changes;
- the UPID can be directly pinpointed on all maps with Universal Map Grids
no matter what kind of scales and projections they have;
- the natural order of the UPID can greatly simplify the property databases;
- the integration of the identifier and geographic coordinates of a UPID can
significantly reduce the storage size (no geographic coordinates needed);
- the UPID can also be used for other purposes such as taxi, postal services and
emergency services due to its accurate location information;
- the UPID does not need to be assigned by government but can be found
by owners themselves, which can save huge amount of costs for the government;
- the UPID can make the exchange of property information among different
real-estate databases very easy and efficient.
