Geological Surveying and mapping mainly refers to the geological survey,
mineral exploration and the preparation of the map of the results of Surveying and
mapping work, including the control survey, surveying and mapping network survey.
In 90s topographic survey, geodetic survey mainly uses the theodolite, range finder,
flat instrument mechanical instrument of Surveying and mapping, and later with
the application of GPS positioning technology in surveying and mapping, geological
mapping accuracy up to a new level. Based on this, this paper discusses and analyzes
the application of Surveying and mapping technology in geological exploration from
different angles.
