Geotude

Geotude in a Nutshell

Origins: Geotude Basics

Currently, we could say we are all familiar with the concept of latitude and longitude as means to idenfity location at needle-pin precision.

Similarly, a Geotude is also used to reference location. However, instead of identifying one "intersection" (between the latitude/longitude of course), a Geotude uses the "area" bounded by integer degrees of latitude/longitude to identify a location anywhere on and off Earth.

While we "count" latitude/longitude by the degrees, a Geotude is identified with a more intuitive string that looks like this: 53781.06.76.40 (incidentally, this is the Geotude to our office :))

Identifying a Geotude

Geotudes are sequentially numbered from left to right (West to East), and top to bottom (North to South).

The smallest numbered Geotude starts at latitude=0°, longitude=-180°.

Since we've already established that a Geotude is bounded integer degrees of latitude and longitude, the total of Geotudes in the world come up to 64, 800. Pretty nifty, eh?

Geotude Hierarchy

Let's assume that a (level 0) Geotude is "square" (in reality, because a Geotude is equal-angled, as in latitude/longitude angle; they differ in dimension depending on their relative location to the equator) like so: Figure 1. A Geotude (or rather, the abstract concept of a Geotude)

We can sub-divide a level 0 Geotude into 100 sub-Geotudes; numbered from 00 to 99: Figure 2. A Geotude can be sub-divided into 100 child Geotudes.

So, each sub-Geotudes can be referenced by 12345.xx.

If we in turn, look at Geotude 12345.xx, we can again sub-divide this sub-Geotude into another 100 sub-Geotudes; numbered from 00 to 99 again: and we get 12345.xx.yy.

And this goes on and on infinitely!

In Memory of Lat/long

You didn't think we'd actually completely abandoned the very foundation of location tracking, did you?

If you've been wondering, yes, latitude/longitude can be converted to Geotude and vice versa! Here is a simple Javascript implementation of the converter.

It is important note that since Geotude is an area, whereas latitude/longtidue is a point; we cannot "really" convert an area to a point or vice versa. What we can do, is established that all Geotude are referenced by the top-left (North-West) point. Hence, the formula for converting latitude/longitude to Geotude is: GT = 500 x floor(90 - lat) + floor(lng + 180) + 10000
