State monitoring of the subsoil - the information basis of the state hydrogeological mapping
The questions of the priority objects choice of hydrogeological mapping in the post-study areas, which had previously been drawn up hydrogeological maps, as well as issues of the optimal composition of work in hydrogeological survey are discussed. It is shown that using the data of the state monitoring of the subsoil as an information basis for mapping, these issues can be solved with maximum efficiency.
