Construction of the reference (vertical) hydrographic surface for the bays of Buenaventura and Málaga, Colombian PacificAbstract
The present paper defines the methodological path used in the project “Vertical Reference Hydrographic Network for the main Colombian maritime ports”, during the generation of reference vertical frame called “Vertical Reference Hydrographic Surface (SHRV2016)” for Buenaventura and Malaga bays in the Colombian Pacific, based on three main components: the mathematical determination of vertical datums associated with historical records of the water level, the establishment of first order geodetic points network, and the measurement of sea surface heights with reference to the WGS84 ellipsoid (World Geodetic System), using GNSS (Global Navigation Satellite System) receivers in differential mode RTK (Real Time Kinematic). The ground reference points were used to have precision vertical control to the datums in the water, and also for the installation of GNSS reference receivers, that were in charge of sending real time differential corrections during the measurement of sea surface heights. These measurements in connection to the calculated vertical datums densification for the area, formed the necessary basis for development the SHRV2016, a model with a spatial resolution of 500 meters, where all water level vertical datums refers to the WGS84 ellipsoid. In addition to standardize measurements made by different users in jurisdictional waters relative to a vertical datum; allowing to take advantage of the benefits of GNSS technology to perform the water level measurement and correction in real-time with the lesser degree of uncertainty during the execution of hydrographic surveying, optimizing time, quality and resources, particularly in places such as Buenaventura and Malaga bays, where the tidal regime makes complex the activity of correction due to the variability in range and phase of the sector, by which makes necessary install multiple tide stations, perform tasks of Surveying and Geodesy in difficult access places, and will wait for include tide gauge records in the final correction of the depths, only until the hydrographic survey will finish. In a medium term, the SHRV will allow the generation of a total tide datums reference model relative to the ellipsoid, covering completely the coastal and island regions of the country, up to the limits of the Territorial Sea, thanks to the combination with satellite altimetry data and observational offshore tools as GPS buoys, which allow the correct fusion with the local models generated in each one of the bays and harbors.The present paper defines the methodological path used in the project “Vertical Reference Hydrographic Network for the main Colombian maritime ports”, during the generation of reference vertical frame called “Vertical Reference Hydrographic Surface (SHRV2016)” for Buenaventura and Malaga bays in the Colombian Pacific, based on three main components: the mathematical determination of vertical datums associated with historical records of the water level, the establishment of first order geodetic points network, and the measurement of sea surface heights with reference to the WGS84 ellipsoid (World Geodetic System), using GNSS (Global Navigation Satellite System) receivers in differential mode RTK (Real Time Kinematic).
