So I've made a coordinate system that's easy to find coordinates for, unlike longitude and latitude, these coordinates are not super-duper precise, but will give you an idea for where someone is, it allows you to find the hemisphere (north, or south), continent, country, and region (kind of).
One downside would be that this is not reverse-engineer-able, it uses a complex equation to make a simple number, since the combinations of numbers are, for the most part, limited, trying to reverse engineer it is hard, instead you would have to manually try and search for the number, though, most of the outputs (Location IDs (
LocationId)) will be unique, meaning if you know their location ID, you can find them.
First, let's define some values
North America = 1 Africa = 2 Europe = 3 Asia = 4 South America = 5 Australia = 6 Antarctica = 7
LongId = ContinentId*(1+2+3+4+5+6+7 (Excluding ContinentId)) North America = 1*(2+3+4+5+6+7) etc...
North America = 27 Africa = 52 Europe = 75 Asia = 96 South America = 115 Australia = 132 Antarctica = 147
Northern Hemisphere = 1 Southern Hemisphere = 2 (it could also be -1)
Americas = 1 Africa&Europe (Europe including Asia) = 2 Australia = 3 Antarctica = 4
Land = 2 Water = 4.5
With all that out of the way, we just need 3 more variables, these ones are way simpler, but they're not just numbers, they're something you have to measure. They are:
EquatorOffset = Distance in land (rounded). This makes the top half of the United States, and some of Canada's EquatorOffset equal to 3
EquatorPosition = Distance in land. A place like Minnesota, North Dakota, Washington, etc... are at EquPos 2.999999, being less than, or equal to 2.9 at their bottoms.
CountryPosition = Distance from west side of landmass in miles.
Ok, now with all of that, to calculate the Location ID, you need to enter the numbers into this equation:
(ContinentLongId*HemisphereId) /(ContinentId+HemisphereId)-1 *(LandMassId/TerrainId) /(EquatorOffset/ContinentId)+EquatorOffset *(EquatorPosition+CountryPosition) /CountryPosition
With this information, my Location ID is approximately
16.3385225038, so with that, where do you think I am?
JK, that would be impossible.
That's literally all you have to do, I created this as a fun experiment to see what I could do with some (mostly) simple information, and see how I could combine it to make a precise number, as long as said precise number represents something identifiable (i.e. a location).
