I am working on publishing a listing of shelters and hostels, I would like to expose my data to anyone who would like to use it. One of the things I would like to do is allow the shelters and hostels to be plotted on a map.
There are three methods of posting locational based data:
This is the traditional street and Avenue system that the postage system uses.
Easting and Northing
These are (usually) used for horizontal and vertical from the a specified datum position. For example, a mountain close to where I live is located at 50° 52′ 10″ N, 115° 39′ 3″ W.
Longitude and Latitude
This is a common grid system that uses two numbers (a coordinate) to pinpoint a location. For example, the same mountain can be fount at 50.869444, -115.650833.
My thoughts so far
The addresses system good for projects in a city but if the location is away from a road (like some hike-to hostels) it does not work so well. My data is already in Easing/Northing, however with everyone using GPS and cell phones now it sounds like longitude and latitude may be more popular?
What type of location system should I chose if I want as many parties as possible to use my data in their work? It's hard to know how the data could be used, but I suspect consumers of my data to be interested in travel, real estate, poverty and government.
