Abstract

An aeromagnetic pre-processing system based on a graphic user interface (GUI) includes an input unit for inputting measured aeromagnetic data, GPS data, and reference magnetic data, a data storage unit for storing individual data, collection data, and edition data on division area data groups obtained after an investigation area is divided, a GUI providing unit for providing a GUI for data input/output, an operation unit for performing an operation to perform pre-processing for each of the division area data groups and collection and leveling of the division area data groups, and a controller for controlling the input unit, the data storage unit, the GUI providing unit, and the operation unit.

Claims

1. An aeromagnetic pre-processing system based on a graphic user interface (GUI), comprising:

an input unit for inputting measured aeromagnetic data, GPS data, and reference magnetic data;

a data storage unit for storing individual data, collection data, and edition data on division area data groups obtained after an investigation area is divided;

a GUI providing unit for providing a GUI for data input/output;

an operation unit for performing an operation to perform pre-processing for each of the division area data groups and collection and leveling of the division area data groups; and

a controller for controlling the input unit, the data storage unit, the GUI providing unit, and the operation unit.

2. The aeromagnetic pre-processing system of claim 1, wherein the data storage unit comprises:

a division data group database (DB) for individually storing the division area data groups;

an integrated DB for collecting and storing the division area data groups; and

an address specification integrated DB for removing survey data beyond the investigation area and unnecessary data corresponding to an overlapping or irregular flight within the investigation area, providing an address to every survey, and then storing the surveys.

3. The aeromagnetic pre-processing system of claim 1, wherein the calculating unit comprises:

a pre-processing operation unit for performing a pre-processing operation for each of the division area data groups with respect to the aeromagnetic data, GPS data, and reference magnetic data, which are read through the input unit;

an integrated DB operation unit for performing an operation to generate an integrated DB by collecting the division area data groups; and

a leveling operation unit for performing an operation to implement conventional leveling and micro leveling.

4. A pre-processing method using an aeromagnetic pre-processing system based on a GUI, the pre-processing method comprising:

a first process of reading, through an input unit, measured aeromagnetic data, GPS data, and reference magnetic data for each division data groups;

a second process of synchronizing the input aeromagnetic data, GPS data, and reference magnetic data to have the same recording time;

a third process of transforming GPS information represented with latitude and longitude to Transverse Mercator (TM) or Universe Transverse Mercator (UTM);

a fourth process of performing correction of a delay corresponding to transceiver spacing and a heading effect corresponding to different flight directions;

a fifth process of constituting an integrated DB by collecting all division data groups stored in a division data group DB of a data storage unit;

a sixth process of removing unnecessary data beyond an investigation area;

a seventh process of selectively removing unnecessary data within the investigation area;

an eighth process of performing specification and edition of an address for each survey of the integrated DB;

a ninth process of performing conventional leveling; and

a tenth process of performing micro leveling.

5. The pre-processing method of claim 4, wherein, in the sixth process, all aeromagnetic data stored in the integrated DB are visualized as flight paths, and the visualized flight paths are provided to a user.

6. The pre-processing method of claim 5, wherein, in the sixth process, the investigation area is configured as a combination of polygonal coordinates in a looped curve shape, and the combination of the polygonal coordinates is overlapped with the aeromagnetic data visualized as the flight paths to separate all aeromagnetic data into internal and external data, thereby selectively removing unnecessary external area data.

7. The pre-processing method of claim 4, wherein, in the seventh process, in order to remove an undesired portion due to an overlapping or irregular flight path within the investigation, area all surveys are separated into segmented survey groups by introducing segment points having a finite number, and a corresponding segment survey to be removed is selectively removed by using a mouse.

8. The pre-processing method of claim 4, wherein, in the eighth process, one survey in the south/north or east/west direction is arbitrarily specified, and separated into surveys by allowing the user to determine whether the one survey is a survey line or tie line, and an address is specified with respect to each of the separated surveys.

9. The pre-processing method of claim 4, wherein, the tenth process comprises a feedback process for allowing the user to derive an optimum result through repetitive trials and errors.
