| RE: Geometrics preliminary MagArrow and MagEx data processing program download | 6 Relevance | 2 years ago | Ahmed Ramadan | Software | |
| Hello Dears, I'm new to Geometrics products and interested in MagArrow. I have some questions please. As a geophysicist, I examined the attached data and applied heading compensation to the measured data. My questions are after applying the 4th difference filter (the last Panel in the attached figure) which is very important for measuring data noise especially comTing from the drone. I found the range to be very high and exceeding +/- 0.1, even after applying low pass filter to reduces the sampling rate of data from 20 Hz to 10 Hz. I think one of the biggest advantages of the MagArrow is that the sensor is suspended 3 meters below the drone to cancel out the effect of the noise coming from the drone, so I need to explain that. Attachment : 4th difference.jpg Secondly, in the attached file of the survey, the range of the total magnetic field data is about 43,000 nanoTesla, while when calculating the IGRF for that region based on longitude and latitude, I found that the range is about 49,000 nT, which is very far from the measured data? Could you please explain to me the answers to these questions because our goal is to explore minerals and not UXO. Kind Regards, Ahmed | |||||
