Abstract
Description
The present invention relates to a digital map production system in which accuracy is improved by checking a real-time reference point in the field of digital map technology. More specifically, the present invention relates to a digital map production system in which a change in geographical information due to a natural or artificial terrain change can be easily confirmed, It is possible to improve the accuracy of the digital map by updating the digital map based on the data of the geographical information collecting device and the geographical information collecting device installed on the ground determined as the check point, The present invention relates to a digital map production system in which accuracy can be improved by confirming a real-time reference point so that accurate information can be generated from a support information collection device.
Generally, a numerical map is a map showing numerical values of geographical / geographical contents to be expressed, and includes a map displaying a numerical value of the water depth, a terrain measurement chart showing the undulation state of the terrain, .
In other words, a digital map is applied to a rendered image by expressing geographical / geographical features of a specific point with numerical information.
Therefore, the digital map must be accurately applied to the displayed image so that the user can easily obtain the geographical / geographical information while viewing the map, and also, the digital map image should be accurately applied to the geographical information Should be shown.
The geographical information may be a coordinate value of the GPS or a coordinate value according to the administrative area unit of the cadastral map. The coordinates of the GPS coordinate value and the cadastral map should correspond to each other, do.
Hereinafter, numerical information such as GPS coordinate values, coordinate values of cadastral maps, and various data measured / collected at actual points will be collectively referred to as geographic information.
As described above, the numerical map is completed by applying geographic information on a map image that is completed by a general drawing operation. As time passes, the actual geographic form may change from existing geographic information due to natural / artificial change.
In addition, errors may occur due to erroneous measurement during the initial production of the digital map, and the displayed topographic information and geographic information may be different.
Therefore, the information of the digital map needs to be updated periodically, more preferably, in real time, and it is required to confirm the error generated in the production.
However, in the past, there was no technical means for updating the digital map and confirming the error, so the digital map once produced was not suitable for adjustment.
In the end, there was an unreasonable necessity to newly produce a digital map for the digital map update.
However, the above-mentioned unreasonable conventional solution is merely a reproduction of the digital map according to the natural / artificial terrain change, and the error between the terrain information and the geographical information due to the limitation of the production system itself using the same digital map production system In other words, the problem of the lack of accuracy of the conventional digital map can not be solved at all without replacing the expensive digital map production system.
As an improved prior art to solve such a problem, there is a " digital map production system in which matching data of geographical information and matching information of geosynchronous coordinates are confirmed and applied to numerical information " through Korean Registered Patent No. 10-0929120.
The above-mentioned Japanese Patent Application No. 10-0929120 discloses a geographical information collecting device for precisely measuring the horizontal distance between installation points and geographical information or geographical information constituting a digital map according to geographical information provided from the geographical information collecting device And comparing the existing geographical information applied to the digital map with the geographical information confirmed to the actual map to check the error of the geographical information compared with the geographical information applied to the digital map, The accuracy and reliability of the map can be improved.
However, the geographical information collecting apparatus is installed using three supports on the ground surface determined as the verification target point. When the floor of the installation site is a hard soil such as sandy soil, muddy soil or tidal flat, It is difficult to collect the precise geographical information and it is difficult to keep the stable horizontal state of the geographical information collecting device constantly and it is troublesome to adjust it from time to time there was.
The present invention has been made in view of the above-mentioned problems in the prior art, and it is an object of the present invention to provide a geographical information management system and a geographical information management method, It is possible to increase the accuracy of the digital map by updating the numerical map and to maintain the stable posture even when the installation place of the geographical information collection device installed on the ground determined as the verification target point is not hard, There is a main object of the present invention to provide a digital map production system which improves accuracy by checking a real time reference point so as to generate accurate information from an information collecting device.

According to the present invention, it is possible to easily confirm the change of the geographical information due to the natural or artificial terrain change, as well as to improve the accuracy of the digital map by updating the digital map based on the erroneous data, The geographical information collecting device installed on the ground determined as the target point can be maintained in a stable posture even when the installation place of the geographical information collecting device is not rigid so that a real time reference point is confirmed so that accurate information can be generated from the support information collecting device The effect of improving the accuracy can be obtained.
