We are looking for a bright software engineer that could develop an Algorithm to encode and decode the longitude and latitude into a digital address that in a format below.

1. Format

[MP] – [0013] [5590]

[Letter#1 Letter#2] - [Number #1] [Number #2]

With two-letter prefix (English alphabet) - and 2 sets of 4 numbers.

Letter #1: ABDEFGKMNPRSUVWXYZ [18 character available]

Letter #2: NPRSUFGKMVWXYZABDE [18 character available]

Note: The use of Letter #1 and Letter # must base on the order character set above. It can be change or shuffle the order later.

[number #2]: 0000 to 9999

[number #2]: 0000 to 9999

2. Range of the latitude/longitude we will cover only (Laos):

-Latitude of 13 Degree North to 23 Degree North

OR: 13.00000000 to 23.00000000

(1 billion different numbers)

-Longitude of 100degree East to 110 degrees East

Or: 100.00000000 to 110.00000000

(1 billion of different number)

3. Resolution of the longitude and latitude

17°58'38.911"N 102°37'35.442"E

Need 3 decimal points for seconds unit for radian format

For decimal format

17.17631315, 104.89793213

Need 8 decimal points for decimal

We know that with this the format we want, we will have about 32.4 billion addresses to cover.

18*18*10^4*10^4 = 32,400,000,000

With longitude/latitude range we need to cover, and with the resolution 8 decimal point we required only 2 billion addresses.

Encode:

> Given latitude and longitude as input (must contain 8 decimal points)

>If out of the range coverage

Decode:

>Given the Digital Address as input

>Output as longitude and latitude with the same resolution (8 decimal points)

Google Plus code is opensource project. You can find the code here

>convert into latitude and longitude

> convert into Google Plus code

>covert into latitude and longitude

>If out of the range of coverage

>If in range of coverage
