This is an area management database.

[0004] Reference numeral 101 denotes a personal computer installed as a terminal, and a set of point data obtained by measurement by processing the area measurement data and the position data together. Is converted into line data to create data indicating a traveling locus. After this process, the travel locus data is transferred to the client 102 via the hub 104 described above. Sign 1

Clients that make up the server system. The client 102 has map data therein and performs editing and registration processing such as position correction of area data. Also,
In the example of the system assumed here, the server 103 and the client 102 have the same OS (Operating

It is necessary to correct this error and obtain a correct running locus at the time of acquiring the area measurement data. By performing parallel or rotational movement on the running locus based on the actual running route, position correction is performed, and a correct running locus is obtained. Conventionally, this position correction processing has been performed on the client 102.

In a mobile communication system using radio, it is important information how far a transmission radio wave of a base station reaches, and therefore, area measurement data is displayed on a map. Creating and managing area diagrams is required. In a conventional area management system, a measuring instrument for acquiring area measurement data indicating the electric field intensity of a radio wave and a personal computer for processing the data are located at remote locations, and data acquisition and data processing are separately performed. In addition, since the measuring instrument does not have a function of displaying a map and managing acquired data, a traveling course at the time of data acquisition is written and managed with a map while traveling. For this reason,
The burden for recording the traveling course is large, and the recorded amount of the traveling course is enormous, making it difficult to search for the traveling result after the measurement.

The present invention has been made in view of such circumstances. By taking the above-described data processing personal computer outdoors and connecting it to an area data measuring device, a map can be wirelessly transmitted from a server and a client. The personal computer reads necessary data such as data, displays measurement points on the personal computer, manages the driving course displayed on the GPS receiver, and performs an efficient area management system and area measurement. The aim is to provide a method.
