Aeromagnetic Anomalies Verification Of Data Acquisition And Data Processing

In this paper, mobile GIS technology and high-precision single-point GPStechnology, design and development of aeromagnetic geophysical anomaly inspectionsystem, which includes data preparation, field data collection and data processing ofthree parts. The system is mainly for geophysical anomalies in the magnetic anomalyverification methods.Data preparation work is new construction and map data preparation. Newconstruction projects including records attribute information, generate fieldverification test area and field verification projects. Map data preparation is used inthe field of basic geographic maps, geological maps, aeromagnetic contour maps andaeromagnetic profiles and other information map generation tile map, called the PDAin the wild. New construction is completed and the data need to be ready tosynchronize data to the PDA, after the end of the field to verify the data collected inthe field need to be synchronized to the PC, for data processing.Field data collection including petrophysical collection, magnetic profilemeasurements, points of interest and track line records. Petrophysical acquisitionrefers to the abnormal position of the magnetic susceptibility measurements on rock,including outlier screening, navigate to outliers and data acquisition. Magnetic profilemeasured at the center of the cross-section through a typical abnormal magnetic fieldvalues on the acquisition, in a rocky outcrop at the outcrop to be collected at themagnetic susceptibility, magnetic profiling constitutes including magnetic profiledesign, navigation and data collection to the collection point. Points of interest in thefield verification process can help explain the unusual point encountered during thefield verification of such points need to record the location and some descriptiveinformation. Track line refers to the field staff to verify the routes, the paper rewrittenArcPad line in track recording method. In the verification process map browsing playsa very important role in relation to the selection of outliers, the magnetic cross-section design, navigate to the target point and the superimposed display of the map and soon.Data processing section mainly for data collected in the field of statistics and theresultant maps and stacked. Statistics include magnetic susceptibility statistics andstatistical parameters, generally in accordance with geological or tectonic movementstatistics, data collection in the field of these fields is not, so you need to add statisticsStatistics field, and then use statistical procedures, and finally according to a certainformat statistical results in excel format output tables.Paper concludes with some conclusions program design and outlook.
