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.

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.
