What are two ways of describing an absolute location other than using geographic coordinates?
You could use a planar coordinate instead of a geographic coordinate. For example: New Orleans, Louisiana, USA is almost exactly at 30°N 90°W. This is its geographic coordinate. You could also say it is at UTM coordinate E210590 N3322576 Zone 16N. This is a planar coordinate based on a particular map projection (the Universal Transverse Mercator projection). Note: There are many kinds of planar coordinates. An address is also a way to use an absolute location. However, you would have to include ALL parts of the address to be truly absolute: For example: 8 Royal Crescent (There could be many places with this address. In what city is this?) 8 Royal Crescent, London (There are many cities with this name.
