Description

TECHNICAL FIELD [0001] The present invention relates to a surveying apparatus for accurately converting a regional geodetic system to a world geodetic system and a surveying method using the same,

The present invention relates to a surveying apparatus for accurately converting a regional geodetic system to a world geodetic system and a surveying method using the same, wherein a total regional station using a reflector is measured, and the surveyed regional geodetic system is converted into a world geodetic system In order to ensure the accuracy of the converted world geodetic system, the world geodetic system is once again surveyed by the GPS surveying device. In order to minimize the measurement errors that may occur when the reflector and the GPS measurement device are provided separately, And a surveying apparatus and a surveying method for positioning the surveying apparatus.

The total station survey generally includes a vertical angle detecting unit for measuring a vertical angle caused by vertical movement of the telescope, a horizontal angle detecting unit for measuring a horizontal angle caused by the horizontal rotation of the main body, a distance measuring unit for measuring a distance from the center of the main body to the reflector, And tilting sensors for measuring and correcting the light intensity. The total station measures the light pulses reflected by the reflector located at the corresponding boundary point and measures the azimuth and distance (slope distance, horizontal angle and altitude Angle).

A GPS survey is a measurement made using a GPS (Global Positioning System) instrument, which receives a carrier emitted by at least four GPS satellites over the earth and measures the exact location and time of origin to determine the distance between these satellites and the GPS instrument To obtain the three-dimensional position information of the GPS instrument.

Explain the business of converting the geodetic reference system from the local geodetic system (Tokyo geodetic system) to the world geodetic system.

In general, Korea's land boundaries are registered and managed in the cadastral map based on the local geodetic system. However, according to the global promotion of the cadastral re-surveying project and the global trend, the conversion to the world geodetic coordinate system based on the three- .

The reason for the global trend to convert the geodetic reference system from the existing regional geodetic system to the world geodetic system is as follows.

First, the geodetic reference system of the country should be accurate and up-to-date because it is the infrastructure information that is the basis of all the location information of the country. New technologies such as satellites are being developed for this purpose. These technologies define the world geodetic system for use worldwide and provide the information. Therefore, the introduction of the world geodetic system is necessary for precise and accurate positioning using the most advanced positioning system.

In addition, as technology advances and information exchange becomes more active, international cooperation organizations recommend that the world use one standard. Therefore, there is a need to convert all the cadastral maps stored in the local geodetic system into the world geodetic system in the period of introducing the world geodetic system in a timely manner in Korea as well as the cadastral rehabilitation project being promoted as a national project.

Describe the work process of the global geodetic conversion project.

The global geodetic system conversion business is carried out in the order of preemption of common points and surveying, conversion of cadastral maps, field inspection survey, and drawing maintenance. Surveying capability of surveying engineer is very important in preemption of common points and surveying.

On-site inspection Look at the surveying process.

Position the reflector at the corresponding boundary point, measure the light pulses reflected from the reflector at the total station, and measure the local geodetic system. Then, the regional geodetic system surveyed at the total station is calculated by applying the conversion coefficient and converted into the world geodetic system. To ensure the accuracy of the transformed world geodetic system, remove the reflector located at the corresponding boundary and then place the GPS instrument at the corresponding boundary where the reflector was located and measure the world geodetic system. Then compare the converted world geodetic system with the world geodetic system through GPS survey.

In this case, even if the GPS instrument is positioned at the same position where the reflector is located, positioning the GPS instrument at the position where the reflector is located is performed by hand, so that the position of the reflector and the position of the GPS instrument do not coincide exactly, There is a problem that an error is caused.

In addition, after converting the regional geodetic system surveyed by the total station to the world geodetic system, it confirms by hand such as verbal comparison among the process of comparing with the world geodetic system by the GPS survey, and there is a problem in the accuracy of the comparison check operation.
