This software is very easy to be used recording the location and geomagnetic element. In the process of marching, you can record the current position (WGS84) of geomagnetic element, longitude, latitude, altitude, address, and photos. All of data can be derived, including photos, and can be opened in the post-processing software such as Google Earth.
The coordinate and gravity information are under the WGS84 coordinate system, including the declination, inclination, total field, hor. intensity, north comp., east comp., vertical comp and grid variation, etc., are calculated adopt the global geomagnetic model (WMM) and the global gravity field model (EGM96, WGS84).
All the information is for reference only.
