Numeric map correction system using GPS {NUMERICAL MAP MAKING CORRECTION SYSTEM USING GPS}

The present invention relates to a digital map correction system using GPS, and more particularly, if there is a change in the building information displayed on the digital map through the confirmation of the GPS, the information corresponding to the modified so that the correction can be made to the digital map. The present invention relates to a digital map correction system using GPS for maintaining the accuracy of the digital map by reflecting it on the digital map while maintaining a stable support state by preventing the camera from being separated from the pitching plate.

Geographic Information System (GIS) is an information system that integrates and processes attribute data related to geographic data. It can efficiently collect various types of geographic information. Refers to a system that collectively includes hardware, software, geographic information, and human resources used to store, update, process, analyze, and output data.

As GIS is combined with Internet technology, Internet-based map retrieval technology, which enables users to conveniently browse the map using the Internet, is becoming more common.

In other words, GIS provides the advantage of easily retrieving location information such as latitude, longitude, address, etc. This GIS provides the geography and map that users need through querying and analyzing spatial data of relational database. It is a system that provides information by converting the information into an appropriate map image.

In addition, the most basic data in constructing a GIS is a numerical map. Digital maps, unlike classical paper maps, are produced by interpreting and numerically editing various terrain data obtained from survey maps, aerial photographs, satellite images, etc., and indexing them and storing them in a file format.

Such numerical maps are also used for various cadastral and topographic maps. Briefly describing the cadastral map and topographic map, the cadastral map is a map in which the location, land number, land cover, boundary, etc. of the land is displayed, and the topographic map is the surface shape, water system, land use, settlement, roads, railways, and various other works. A map showing the placement status of the.

Here, the placement objects displayed on the topographic map may change relatively depending on the type. For example, the buildings displayed on the topographic map frequently change, so the information of the buildings that changes frequently is accurately reflected on the topographic map (hereafter referred to as the numerical map because it corresponds to one type of topographic map and numerical map). In order to be able to do so, it is necessary to update the numerical map at a rapid cycle.

However, it is not possible for the manager of the institution that manages the digital map to immediately recognize the change of the building in the digital map and confirm the change of the building.

Meanwhile, Korean Patent Registration No. 10-1589928 (2016.02.01.) Discloses a 'digital map update system of a changed feature by checking GS'.

However, such a conventional digital map updating system is difficult to shoot smoothly as the camera is loosened from the camera mounting screws provided on the pitching plate due to external force or incomplete coupling, or is detached. Mega has a problem that can be broken.

It is made of a transparent material so that the visual confirmation of the display unit provided on the rear portion of the digital camera CAM is not disturbed, and the lower portion is protected while the close contact member 440 is provided on the lower portion, and the coupling groove ( Departure from 273a) is prevented,
The pressing means 430,
A pressing plate 431 disposed above the digital camera CAM and having a pressing member 435 on a lower surface thereof;
A pressure bar 432 having a lower portion fixed to the pressure plate 431 and an upper portion passing through the support bar 420;
The pressing plate 431 is coupled to the outside of the pressing bar 432 so as to be positioned between the pressing plate 431 and the support bar 420, and thus the pressing member 435 is pressed by the digital camera CAM. A spring 433 in close contact with the camera CAM;
A handle member 434 provided on an upper portion of the pressure bar 432; And
An adjustment ring 437 coupled to the outside of the pressure bar 432 to be positioned between the spring 433 and the support bar 420, and extending upward from the control ring 437 to support the support bar ( Passing through the 420, and includes a housing 438 that is screwed up and down to the support bar 420, and the spring 433 by pressing or releasing the spring 433 while being raised and lowered by rotation, Adjusting member 436 for adjusting the elastic force of the),
The support means 450,
A support member 451 which is made of a metal material and forms a 'c' shape in which a lower portion thereof is opened and is coupled to an upper portion of the fixing plate 410 to rigidly reinforce an upper portion of the fixing plate 410;
A connection bar 452 having a lower portion fixed to the support member 451 and an upper portion passing through the support bar 420; And
Screwed to the connection bar 452 so as to be positioned on the upper and lower portions of the support bar 420, the connection to adjust the separation distance between the digital camera (CAM) and the support bar 420 while moving up and down according to the rotation. Including member 453 Digital map correction system using GPS.
