FIG. 5 is a diagram showing a processing flow of the automatic mail attachment position information coordinate system converting apparatus according to the embodiment of the present invention. The operation of the automatic mail attachment position information coordinate system converting apparatus when a mail is received will be described with reference to the flowchart of FIG.

At S1, a new mail text is obtained.
First, get the body of the email, and then get the attached file. In S2, the first identifier “<” in the mail text is searched. If there is such a character, in S3, the preceding character string is obtained (any character of A, Z, T, N).
If there is no "<" character, it is checked in step S4 whether a file is attached. If there is no file attachment, the process proceeds to step S1 to acquire the next mail.
If there is a file attachment, in step S5, the content of the attached file
Get t-Type and check if it is pos.nav. C
If the ontent-Type is not pos.nav, the process proceeds to S1.

At S6, the coordinate system of the original position information is obtained. In S7, if the original coordinate system has not been specified,
By looking inside “<”, it is automatically determined which coordinate system. In step S8, a character ">" is searched to determine whether or not position information is included. If there is no corresponding character, S
In step 9, the next character string processing is performed. In S11, it is checked whether the reading has been completed up to the end of the file. If the reading has been completed to the end, an end process is called in S12.
In the case of NO, the process is repeated from S1.

If there is a ">" character in S8, the character string after ">" is obtained in S10. In S13, the coordinate system after conversion is obtained. If the coordinate system after the conversion is not specified (NO), the contents of “<>” are checked in S14, and the automatically determined coordinate system is used as it is. If a coordinate system has been designated in S13, a coordinate system acquisition process after conversion is performed in S15, a coordinate system is calculated in S16, and the process starts again from S1.

In this way, by assigning the coordinate system identifier, the side receiving the position information can convert the coordinate information into the coordinate system managed by itself through the position information coordinate system automatic conversion device, and It can be used. As a result, a single center can be used irrespective of the navigator, and the system cost, personnel cost, and maintenance cost of the center can be reduced, and an efficient dynamic management system can be constructed. Furthermore, by using the world standard of e-mail (POP3, SNMP), it is possible to absorb the difference in protocol between each system.
