Proposing a New Strategy to Make Precise Re-leveling Observations of Iran in Vertical Geodynamical Studies

The technique of precise leveling is certainly the most precise in gathering height difference observations. The main limitation of the mentioned technique is its high cost and low speed characteristics. Hence، for the purpose of repeating the precise leveling measurements (re-leveling)، which is necessary for vertical geodynamical studies، it is important to gather these observations in an optimum manner. The main purpose of this study is analyzing the characteristic features of the vertical deformation in Iran. This would assist us in concentrating the measurements in the areas that are more prone to vertical deformation as well as the analysis of vertical deformation has a priority in them. For this purpose، various kinds of data from geology، geophysics، seismology، geodesy as well as the population densities have been put together and analyzed. Result of this analysis is a new strategy to make precise re-leveling observations in Iran in a optimum way needed for vertical geodynamical studies، as a solution to the request of National Cartographic Center of Iran.
