Abstract of the Invention: The geographic coordinate encoding method described in this invention consists of the following steps: receiving geographic coordinate values consisting of latitude or longitude values; separating the sign from the coordinate values; separating the remainder by dividing by 10 (with the remainder taken), and multiplying the result by 100,000. Then, it is converted from decimal to base thirty-two using a predefined base thirty-two code. The part of the coordinate value is then separated by dividing without remainder by 10. The resulting decimal number is then converted back to base thirty-two using a predefined base thirty-two code. Finally, the numerator and denominator after conversion are cascaded, and the sign is returned to its original form. The geographic coordinate decoding method described in this invention consists of the following steps: receiving the encoded geographic coordinate values, which includes the step of separating the sign from the encoded geographic coordinate values. The method for encoding geographic coordinates according to this invention consists of the following steps: receiving geographic coordinate values consisting of latitude or longitude values; separating the sign from the coordinate value; performing remainder division by multiplying the result by 10; multiplying the result by 100,000; then converting it to base ten into thirty-two predefined codes; and separating the coordinate parts by performing whole division by 10. The resulting base ten digits are then converted back to thirty-two using the predefined codes, and the sign is returned to its original form. The method for decoding geographic coordinates according to this invention consists of the following steps: receiving the encoded geographic coordinate value; separating the sign from the coordinate value; converting the remainder by dividing by 10; and then converting the resulting base ten digits back into thirty-two using the predefined codes, cascading them, and returning the sign. The process involves extracting the sign from the encoded geographic coordinates, removing the "+" or "-" sign, converting the first character to base 10 and multiplying the result by 10, converting the remaining four characters to base 10 and dividing the result by 100,000, adding the first result to the second result, and re-inserting the sign. The geographic coordinate encoding method described in this invention involves receiving geographic coordinates consisting of latitude or longitude values, extracting the sign from the coordinates, performing remainder division by 10, multiplying the result by 100,000, converting it to base ten into a predefined code of thirty-two, and separating the coordinate components by performing whole-division by 10. The resulting base ten digit is then converted back to thirty-two using a cascading sequence of the code, and the sign is re-inserted. The geographic coordinate decoding method described in this invention involves receiving the encoded geographic coordinates. This process involves extracting the sign from the encoded geographic coordinates, removing the "+" or "-" sign, converting the first character to base 10 and multiplying the result by 10, converting the remaining four characters to base 10 and dividing the result by 100,000, adding the first result to the second result, and returning the sign value to its original form.
