Apparatus and method using compressed codes for comprising latitude/longitude information
First Claim
1. A method for compressing both latitude and longitude data into compressed codes;
- the method comprising the steps of;
taking Latitude/longitude data in decimal format or converting all other formats into decimal format;
adding 90 degrees to the latitude data and 180 degrees to the longitude data in order to shift them into positive values;
eliminating the decimal points and converting the latitude and longitude data in decimal into 5 symbols of 36 based numbers respectively, say (La1 La2 La3 La4 La5)36 and (Lo1 Lo2 Lo3 Lo4 Lo5)36; and
interlacing these two numbers and inverting a final format, (La5 Lo5 La4 Lo4 La3 Lo3 La2 Lo2 La1 Lo1)36.

Abstract
A new human interface scheme compresses geographical information, latitudes and longitudes, into a 10 symbols of 36 radices number systems which are based on 36s. It is to simplify the conventional representation of the latitudes and longitudes into much easier to be remembered and accessed by human beings, 10 symbols of 36 radices numbers, “Universal Geo Numbers”. The 5 symbols here can give the accuracy for latitudes and longitudes down to 5 meters which should be enough to accommodate the specifications for most geographic navigation related systems (i.e. GPS/GLONASS) and navigation equipments in the consumer market. The apparatus includes all means that comprise latitude/longitude information into the compressed codes for interfacing between human and machines. A technique for compressing latitude and longitude data into a compression code comprises the steps of: taking Latitude/longitude data in decimal format or converting all other formats into decimal format; adding 90 degrees to latitude values and 180 degrees to longitude values in order to shift them into the positive values; eliminating the decimal points and converting the latitude and longitude values in decimal into 5 symbols of 36 based numbers respectively; and interlacing these two numbers inverting a final format. The present invention further includes a decimator, an adder, a converter and an interlacer for performing the step of above method.
