One of the main advantages of digital imaging - the ability to create highly informative models of studied objects and terrain , which is achieved by the use of vector graphics primitives , as in the image plane and in the space of the stereo . Digital photogrammetry is available for many sectors of the economy , as does not require expensive equipment. However, the accuracy of the decided tasks affects the fact that the digital photographs have lower depictive properties and informativeness, with their comparison with the photographs, furthermore for their working large computational power be required.  Under the contemporary conditions ground-based stereophotogrammetrical survey, with the smaller cost of operation, allows rapidly, and also in the regime “real time”, to obtain the large volumes of information about the object being studied .

Digital compact proton magnetometer was created for measure the geomagnetic fields, including the fields of high heterogeneity. We described design of the instrument and its principles of operation. This device is using implemented digital filtering techniques and Prony method to determine the frequency of the desired signal. The experiments were made in the fields of high heterogeneity and demonstrated the possibility of precise measurements in the fields with a gradient of up to 8 mT / m. The device can be used as a metal detector, as well as for magnetic prospecting, geological studies, etc.
