Real data extraction process and procedure of geophysical exploration profile

Abstract

In this paper, we present an open python procedure with Jupyter notebook, for data extraction and vectorization of geophysical exploration profile. Constrained by observation routes and traffic conditions, geophysical exploration profiles tend to bend curved roads for easy observation, however, it must be projected onto a straight line when data processing and analyzing. After projection, we don't know the true position of the obtained crustal structure. Nonetheless, when the results used as an initial constraint condition for other geophysical inversion, such as gravity inversion, we need to know the true position of the data rather than the distance to the starting point. We solved this problem by profile vectorization and reprojection. The method can be used for extraction data of various geophysical exploration profiles, such as seismic reflection profiles, gravity profiles.
