Abstract
One of the objectives of the Geocentric Reference System for the Americas (SIRGAS) is to establish a unified Earth’s gravity field-related vertical reference system that meets the Global Geodetic Observing System (GGOS)’s requirements. This statement implies the homogenization and unification of the National Vertical Reference Systems (NVRS) existing in the SIRGAS and their integration into a International Height Reference System (IHRS). At present, different strategies based on the combination of local (e.g. levelling, terrestrial gravity data) and global observations (e.g. global models, GNSS positioning) are under consideration. However, most of them are not immediately applicable in South America due to the differences in the definition and realization of the local height systems. In this work, it is proposed an inventory of the available data and the implementation of a common metadata base in order to provide sufficient information for a consistent characterization of each NVRS. This structure must allow the identification of the different standards and specifications applied for the establishment of those systems and the needs of complementary actions for connecting them, including the standardization of the existing height data. The main goal of this approach is however the minimization of those inconsistencies produced by data unavailability, unknown discrepancies, different data collecting and processing strategies, accuracy, and other non-evaluated errors. Based on results for a case study (or test country) in South America, it is proposed a road map for the inventory of vertical systems established with metadata.
