Abstract

A GPS positioning system comprises a fixed station and a mobile station. The mobile station has: positional positioning means; imaging means; direction detecting means; and arithmetic processing means. The positional positioning means measures positional coordinates by receiving radio wave from a satellite. The imaging means is arranged in a predetermined position for the GPS positional positioning means. The direction detecting means detects a photographing direction during photographing by the imaging means. The arithmetic processing means forms landscape data in which imaging data that is an output from the imaging means is associated with orientation data that is an output from the direction detecting means.

Claims

1. A GPS positioning system, comprising:

a fixed station; and

a mobile station, wherein

(a) said mobile station includes;

positional positioning means;

imaging means;

direction detecting means; and

arithmetic processing means,

(b) said positional positioning means is GPS positional positioning means that measures positional coordinates by receiving radio wave from a satellite,

(c) said imaging means is imaging means arranged in a predetermined position for said GPS positional positioning means,

(d) said direction detecting means is direction detecting means that detects a photographing direction during photographing by said imaging means, and

(e) said arithmetic processing means is arithmetic processing means that forms landscape data in which imaging data that is an output from said imaging means is associated with orientation data that is an output from said direction detecting means.

2. The GPS positioning system according to claim 1, wherein

positional coordinates data found by said GPS positional positioning means is associated with said landscape data.

3. The GPS positioning system according to any one of claim 1 and 2, wherein

said system comprises time detecting means that detects photographed time during photographing by said imaging means, and the photographed time is added to said landscape data.

4. The GPS positioning system according to any one of claims 1 to 3, comprising:

communication means that transmits said landscape data to a data server arranged in a remote place.

5. The GPS positioning system according to any one of claims 1 to 3, wherein

said arithmetic processing means is constituted so as to synthesize a plurality of imaging data based on a plurality of landscape data and orientation data, which have been obtained at the same positioning point.

6. The GPS positioning system according to claim 1, comprising:

a certifying means for obtaining certification data for certifying the operator to be a certain individual from a positioning operator, wherein

the certification data on the operator are associated with the landscape data.

7. The GPS positioning system according to claim 6, wherein

the certification data can be used as data for controlling access in a data server.
