发明名称 Method of transforming geographic coordinate
摘要 A method of transforming a geographic coordinate to a geographic location code includes the steps of: retrieving a latitude value and a longitude value of the geographic coordinate; quantizing the latitude value to a first integer value; quantizing the longitude value to a second integer value; converting the first integer value to a first code string, said first code string including a first digit representing a non-numeric character, a second digit representing a non-numeric character, and a third digit representing a numeric character; converting the second integer value to a second code string, said second code string including a fourth digit representing a non-numeric character, a fifth digit representing a non-numeric character, and a sixth digit representing a numeric character; and combining the first code string and the second code string to obtain the geographic location code having a fixed pattern of radix in a mixed radix notation system representation.
