Abstract:

Solving Multiple Attribute Group Decision Making (MAGDM) problems has become one of the most important researches in recent days. In situations where the information or the data is of the form of an Intuitionistic Triangular Fuzzy Number (ITrFN) or Intuitionistic Trapezoidal Fuzzy Number (ITzFN), a new distance function is defined for ranking the alternatives in the decision making process. After processing the decision information through a sequence of arithmetic aggregation operators, namely, the Intuitionistic Triangular Fuzzy Weighted Arithmetic Averaging (ITrFWAA), Intuitionistic Triangular Fuzzy Ordered Weighted Averaging (ITrFOWA) operator and the Intuitionistic Triangular Fuzzy Hybrid Aggregation (ITrFHA) operator, the proposed distance function is utilized to rank the best alternative. A model is proposed to solve MAGDM problems using the developed distance formula defined for ITrFNs. Numerical illustration is provided and comparisons are made with some of the existing MAGDM models and ranking procedures.

Abstract:

ITRFs and ITRF like reference frames have a drawback that limits or makes its wide use difficult while surveying in the Russian Federation. These are significant velocities of changing geodetic stations’ coordinates throughout the entire territory. It leads to necessity of reducing reference geodetic stations and survey points positions from reference epoch to observation ones and vice versa. To avoid this necessity for the most of surveys in the Russian Federation territory, a transformation model [1] of relative behaviour of GSK-2011 and ITRF-2014 reference frames was created. Unfortunately, the model does not work properly in the Far East. That is why in this paper a new, regional transformation model that represent relative behaviour of GSK-2011 and ITRF-2014 reference frames in the territory was described. As it was shown in the paper, the result is equivalent to setting a new, auxiliary version of GSK-2011 reference frame in the Far East territory – GSK-2011-FE, that has no drawbacks of ITRF-like systems. Both frames coincide with each other at the reference epoch t0 and relate by a transformation of angular motion at an epoch t.

Abstract:

AbstractThe PTRF is based on 43 sites with 64 SSC collocation points with the optimum geographic distribution, which were selected from all stations of the ITRF89 according to the criterion of the minimum value of the errors of 7 parameters of transformation. The ITRF89 was computed by the IERS Terrestrial Frame Section in Institut Geographique National - IGN and contains 192 VLBI and SLR stations (points) with 119 collocation ones. The PTRF has been compared with the ITRF89. The errors of the 7 parameters of transformation between the PTRF and 18 individual SSC as well as the mean square errors of station coordinates are of the same order as those for the ITRF89. The transformation parameters between the ITRF89 and the PTRF are negligible and their errors are of the order of 3 mm.

Abstract:

Two coordinate systems used in Turkey, namely the ED50 (European Datum 1950) and ITRF96 (International Terrestrial Reference Frame 1996) coordinate systems. In most cases, it is necessary to conduct transformation from one coordinate system to another. The artificial neural network (ANN) is a new method for coordinate transformation. One of the biggest advantages of the ANN is that it can determine the relationship between two coordinate systems without a mathematical model. The aim of this study was to investigate the performances of three different ANN models (Feed Forward Back Propagation (FFBP), Cascade Forward Back Propagation (CFBP) and Radial Basis Function Neural Network (RBFNN)) with regard to 2D coordinate transformation. To do this, three data sets were used for the same study area, the city of Trabzon. The coordinates of data sets were measured in the ED50 and ITRF96 coordinate systems by using RTK-GPS technique. Performance of each transformation method was investigated by using the coordinate differences between the known and estimated coordinates. The results showed that the ANN algorithms can be used for 2D coordinate transformation in cases where optimum model parameters are selected.

Abstract:

According to the Order of the Ministry of Agrarian Policy of Ukraine, published in 2016, about the procedure for using the national coordinate system UCS-2000, this was the first time officially presented parameters of the Helmert transformation from the UCS-2000 system to the ITRF-2000 system. However, all software products are used for communication between various coordinate systems as the main coordinate system, WGS-84. The Helmert transformation parameters between the UCS-2000 and WGS-84 systems are found for the new realization of WGS-84 (G1762) based on GPS data and the old realization of the WGS-84, based on the US Satellite Navigation System, known as DOPPLER Transit. It is shown that the use of the transformation parameters of the old realization WGS-84 for the processing of present GPS measurements will result in a systematic error of the order of 0.6 m. Obtained transformation parameters can be used as the first approximation to obtain accurate Helmert transformations based on GPS measurements at points with known coordinates in the UCS-2000 system. The described procedure for determining the parameters will be especially useful in the case when a more accurate connection will be established between the systems ITRFyy and WGS-84, than the current one.

Abstract:

Este trabalho objetivou estudar a seletividade dos inseticidas carbaril, deltametrina, paratiom metílico, permetrina e triclorfom em relação a Ascia monuste orseis (Godart) (Lepidoptera: Pieridae) e a seus predadores Brachygastra lecheguana Latreille e Protonectarina sylveirae (Saussure) (Hymenoptera: Vespidae). Por meio de curvas de concentração-mortalidade e das concentrações letais para 90% da população (CL90), calcularam-se os índices de seletividade diferencial (ISD90), de toxicidade relativa, e de tolerância relativa (ITRe90). O paratiom metílico e triclorfom apresentaram seletividade em favor de B. lecheguana (ISD90 = 2,83 e 1,75) e P. sylveirae (ISD90 = 2,95 e 3,59) em relação a A. monuste orseis. Deltametrina e permetrina apresentaram seletividade em favor de P. sylveirae (ISD90 = 1,98 e 2,70) em relação a A. monuste orseis, mas não apresentaram seletividade em favor de B. lecheguana (ISD90 = 0,21 e 0,64). B. lecheguana foi menos tolerante a deltametrina, permetrina e triclorfom do que P. sylveirae (ITRe90 = 9,36, 4,23 e 2,05), e mais tolerante ao carbaril (ITRe90 = 0,14). Os predadores apresentaram tolerância semelhante ao paratiom metílico (ITRe90 = 1,04). As curvas de concentração-mortalidade do carbaril, permetrina e triclorfom em ambos os predadores, de deltametrina em B. lecheguana, e de paratiom metílico em P. sylveirae, apresentaram maiores inclinações do que as curvas em A. monuste orseis.

Abstract:

Abstract. At present, ITRS series reference frameworks are widely used in the world. The results of GNSS are mostly based on the ITRF framework. Transform from ITRF to CGCS2000 is not easy, which restricts the promotion and use of CGCS2000. The conversion relationship between CGCS2000 and ITRF framework has imminent practical significance. This paper constructs the epoch reduction and frame conversion two-steps model which estimated the nonlinear model to solve the appeal problem. Effective test show that the nonlinear model accesses an improvement in not only precession but also accuracy relative to the tradition model.

Abstract:

Zusammenfassung. Die vorliegende Untersuchung überprüft die Konstruktvalidität einer 16 Items umfassenden Kurzversion der Integrated Teacher Report Form (ITRF), einem universellen und unterrichtsrelevanten Verhaltensscreening zur Diagnostik des externalisierenden Verhaltens von Schüler_innen im Klassenraum. 107 Lehrkräfte bearbeiteten für insgesamt 1048 Schülerinnen und Schüler der ersten bis sechsten Klasse die ITRF sowie zusätzlich jeweils eines von drei im deutschsprachigen Raum etablierten Beurteilungsverfahren. Die Analyse der konvergenten und diskriminanten Validität erfolgt anhand einer Multitrait-Multimethod (MT-MM) Korrelationsmatrix sowie einem strukturprüfenden Correlated Trait-Correlated Method minus 1 [CT-C(M-1)] Modell zur separaten Analyse des Einflusses der Konstrukte (lernbezogene / aufmerksame Verhaltensprobleme, oppositionelle / störende Verhaltensprobleme) und der Methoden (ITRF, zusätzliches Beurteilungsverfahren) auf die erzielten Werte der Beurteilungen. Die Ergebnisse zeigen, dass sich die Stärke der theoretisch postulierten Korrelationen mit den empirischen Daten erwartungskonform abbilden lassen, was auf konvergente und diskriminante Validität hinweist. Die Varianz der ITRF-Werte lässt sich zu einem größeren Anteil durch das zu messende Konstrukt als durch methodenspezifische Einflüsse erklären. Somit liefern unsere Befunde Evidenz für eine angemessene Konstruktvalidität des Verfahrens, weshalb sich die Kurzversion der ITRF für den praktischen Schuleinsatz eignet.

Abstract. A dynamic datum denotes a coordinate datum in real-time linked with the International Terrestrial Reference Frame (ITRF) in order to provide a dynamic ITRF-like datum to the users. The ITRF is dynamic and updating every few years as its stations’ coordinates consider the motion of earth’s tectonic plate and other deformations. This paper is an effort to review the implementation of dynamic geocentric datum techniques from a few countries. An overview of dynamic geocentric datum implements Malaysia, Australia, New Zealand, Uzbekistan, Israel and Brunei will be summarized to support the future application. Thus, a review consists of a type of datum; datum parameters, reference frame and epoch will be discussed and outlined. This initiative is the significance for the advancement of the future datum development.

AbstractThe International Earth Rotation Service (IERS) was established in 1987 by the International Astronomical Union (IAU) and the International Union of Geodesy and Geophysics (IUGG), and it began operation on 1 January 1988. The primary objectives of the IERS are to serve the astronomical, geodetic and geophysical communities by providing the following: •The International Celestial Reference System (ICRS) and its realization, the International Celestial Reference Frame (ICRF).•The International Terrestrial Reference System (ITRS) and its realization, the International Terrestrial Reference Frame (ITRF).•Earth orientation parameters required to study Earth orientation variations and to transform between the ICRF and the ITRF.•Geophysical data to interpret time/space variations of the ITRF with respect to the ICRF, i.e., of the Earth orientation parameters, and to model such variations.•Standards, constants and models (i.e., conventions) encouraging international adherence.This presentation primarily covers the first three IERS functions from the operational point of view.

In the modern geodesy and precise engineering surveying, we often choose ITRF reference frame as the measurement benchmark for research. In some special projects, however, it is difficult to directly get the coordinates of points by GPS, and the visibility conditions between points have also been limited. According to this problem, we propose a new method combining GPS survey and gyrostatic orientation technology, to access the ITRF coordinates of control points indirectly, and analysis and research the related important issues.

Using international reference frame ITRF08, we revealed absolute tectonic velocities of GPS sites with the slip rate to the east between 22 to 25 mm/year, to the south between 4 to 8 mm/year. The present strain rate was determined from present tectonic velocities that were consistent with the recent strain rates determined from seismic profiles, thickness of Pliocene - Quaternary sediments. Present day strain rate varying from 10 to 30 nano per year indicated that the region has been deformed weakly, in a stable tectonic regime.

Abstract:

Abstract The kinematics of the present-day deformation in the western Alps is still poorly known, mostly because of a lack of direct measurements of block motion and internal deformation. Geodetic measurements have the potential to provide quantitative estimates of crustal strain and block motion in the Alps, but the low expected rates, close to the accuracy of the geodetic techniques, make such measurements challenging. Indeed, an analysis of 2.5 years of continuous GPS data at Torino (Italy), Grasse (France), and Zimmerwald (Switzerland), showed that the present-day differential motion across the western Alps does not exceed 3 mm/yr [Calais, 1999]. Continuous measurements performed at permanent GPS stations provide unique data sets for rigorously assessing crustal deformation in regions of low strain rates by reducing the amount of time necessary to detect a significant strain signal, minimizing systematic errors, providing continuous position time series, and possibly capturing co- and post-seismic motion. In 1997, we started the implementation of a network of permanent GPS stations in the western Alps and their surroundings (REGAL network). The REGAL network mostly operates dual frequency Ashtech Z12 CGRS GPS stations with choke-ring antennae. In most cases, the GPS antenna is installed on top of a 1.5 to 2.5 m high concrete pilar directly anchored into the bedrock. The data are currently downloaded once daily and sent to a data center located at Geosciences Azur, Sophia Antipolis where they are converted into RINEX format, quality checked, archived, and made available to users. Data are freely available in raw and RINEX format at http://kreiz.unice.fr/regal/. The GPS data from the REGAL network are routinely processed with the GAMIT software, together with 10 global IGS stations (KOSG, WZTR, NOTO, MATE, GRAZ, EBRE, VILL, CAGL, MEDI, UPAD) that serve as ties with the ITRF97. We also include the stations ZIMM, TORI, GRAS, TOUL, GENO, HFLK, OBER because of their tectonic interest. We obtain long term repeatabilities on the order of 2-3 mm for the horizontal components, 8-10 mm for the vertical component. Using a noise model that combines white and coloured noise (flicker noise, spectral index 1), we find uncertainties on the velocities ranging from 1 mm/yr for the oldest stations (ZIMM, GRAS, TOUL, TORI, SJDV) to 4-5 mm/yr for the most recently installed (CHAT, MTPL). Station velocities obtained in ITRF97 are rotated into a Eurasian reference by substracting the rigid rotation computed from ITRF97 velocities at 11 central European sites located away from major active tectonic structures (GOPE, JOZE, BOR1, LAMA, ZWEN, POTS, WETT, GRAZ, PENC, Effelsberg, ONSA). The resulting velocity field shows residual motions with respect to Eurasia lower than 3 mm/yr. We obtain at TORI, in the Po plain, a residual velocity of 2.3+ or -0.8 mm/yr to the SSW and a velocity of 1.9+ or -1.1 mm/yr at SJDV, on the Alpine foreland. These results indicate that the current kinematic boundary conditions across the western Alps are extensional, as also shown by the SJDV-TORI baseline time series. We obtain at MODA (internal zones) a residual velocity of 1.2+ or -1.2 mm/yr to the SSE. The MODA-FCLZ baseline show lengthening at a rate of 1.6+ or -0.8 mm/yr. These results are still marginally significant but suggest that the current deformation regime along the Lyon-Torino transect is extension, as also indicated by from recent seismotectonic data. It is in qualitative agreement with local geodetic measurements in the internal zones (Briancon area) but excludes more than 2.4 mm/yr of extension (FCLZ-MODA baseline, upper uncertainty limit at 95% confidence). Our results indicate a different tectonic regime in the southern part of the western Alps and Provence, with NW-SE to N-S compression. The GRAS-TORI baseline, for instance, shows shortening at a rate of 1.4+ or -1.0 mm/an. This result is consistent with seismotectonic data and local geodetic measurements in these areas. The Middle Durance fault zone, one of the main active faults in this area, is crossed by the GINA-MICH baseline, which shows shortening at a rate of 1.0+ or -0.8 mm/an. This result is only marginally significant, but confirms the upper bound of 2 mm/yr obtained from triangulation-GPS comparisons. The REGAL permanent GPS network has been operating since the end of 1997 for the oldest stations and will continue to be densified. Although they are still close to or within their associated uncertainties, preliminary results provide, for the first time, a direct estimate of crustal deformation across and within the western Alps.

Abstract:

The paper deals with a high-precision geodetic network densification by means of GNSS based geodetic solutions, in the view of the fact that the initial data are represented in different reference frames. Indeed, reference station positions are represented in GSK-2011 terrestrial reference frame whereas GNSS satellites` ephemeris are represented in other reference frames, such as ITRFs, WGS84, etc. Two methods are considered in the paper to provide GNSS observations with a correct processing procedure

Abstract:

Pemantauan posisi Candi Borobudur bertujuan untuk menjaga warisan dunia. Salah satu caranya adalah dengan pembangunan bench mark (BM) atau titik kontrol untuk pemantauan deformasi menggunakan Global Positioning System (GPS). Pengukuran menggunakan teknologi GPS untuk pemantauan stabilitas Candi Borobudur telah dilakukan pada tahun 2002, 2003, dan 2012, menggunakan Global Kalman Filter VLBI dan analisis GPS dan mengacu pada ITRF2000 untuk menganalisis pergeseran horisontal. ITRF menuntut pemutakhiran data koordinat titik-titik kontrol secara periodik. Perbedaan penggunaan versi ITRF pada pengolahan data GPS berdampak pada perbedaan ketelitian estimasi posisi, besar kecepatan dan arah pergeseran titik-titik kontrol. Tujuan dari penelitian ini adalah untuk mengukur estimasi posisi, kecepatan, dan arah pergerakan dari titik control GPS berdasarkan data 2003 dan 2012 dan mengacu pada ITRF2008. Masing-masing kala melalui tahapan regional processing dan local processing. Koordinat dari hasil local processing GAMIT/GLOBK selanjutnya dibandingkan dengan koordinat hasil olahan mengacu ITRF2000 yang telah ditransformasi menjadi koordinat mengacu ITRF2008. Analisis pergeseran titik berdasarkan koordinat dan hasil dari data 2003 dan 2012. Penelitian ini menghasilkan bahwa perbedaan posisi dan akurasi pada pengolahan regional dan lokal mengindikasikan transformasi dari ITRF2000 ke ITRF2008 berada pada standar deviasi yang dihasilkan GAMIT dan GLOBK yang mengacu pada ITRF2008. Selanjutnya, rata-rata nilai pergeseran horisontal periode 2003 dan 2012 adalah 261 mm arah tenggara (SE) yang serupa dengan penggunaan ITRF2000 pada penelitian sebelumnya. Secara umum, perataan jaring Candi Borobudur yang mengacu pada ITRF 2008 lebih akurat dibandingkan penelitian sebelumnya yang mengacu pada ITRF2000.

Abstract:

Oxytocin (OT) mediates social habituation in rodent model systems, but its role in mediating this effect in other vertebrates is unknown. We used males of the African cichlid fish, Astatotilapia burtoni, to investigate two aspects of isotocin (IT; an OT homolog) signaling in social habituation. First, we examined the expression of IT receptor 2 (ITR2) as well as two immediate early genes in brain regions implicated in social recognition. Next, we examined IT neuron activity using immunohistochemistry. Patterns of gene expression in homologs of the amygdala and hippocampus implicate IT signaling in these regions in social habituation to a territorial neighbor. In the preoptic area, the expression of the ITR2 subtype and IT neuron activity respond to the presence of a male, independent of familiarity. Our results implicate IT in mediating social habituation in a teleost.

Abstract:

Improving the accuracy of points coordinates determination from geodetic networks with the use of modern space geodesy techniques (GPS, SLR, VLBI, DORIS) identified factors that were earlier considered as insignificant. Such factors include the movement of tectonic plates. This made possible the transition from the static coordinate system model to the kinematic one. For the effect of the tectonic plates movement on the points coordinates you must know kinematic parameters of the tectonic plates movement – the Euler vector parameters – angular velocity of the tectonic plates rotation and the poles rotation coordinates (latitude and longitude) of tectonic plates. Many modern kinematic models of tectonic plates are used observations, performed by geophysical methods, to estimate kinematic parameters of the tectonic plates movement. The article presents the algorithm that allows to estimate the parameters of the tectonic plates movement from mathematical processing of geodetic measurements carried out at points distributed over the surface of tectonic plates. Based on the presented algorithm the EULER program was developed in the algorithmic FORTRAN language, which was experimentally tested. The analysis results showed that the parameters of the Euler vector obtained by the EULER program are in good agreement with the results obtained by using ITRF 2005 and ITRF 2008 models.

Abstract:

From a network of ninety-six (96) Continuously Operating Reference Stations (CORS), the Department of Survey and Mapping Malaysia (DSMM) has developed a reliable real-time data streaming service known as the Malaysia Real-Time Kinematic GNSS Network (MyRTKnet). MyRTKnet is now operating on Leica SpiderNet system that is configured to provide coordinate to users in Geocentric Datum of Malaysia 2000 (GDM2000). As the name implied, GDM2000 is a geocentric datum for Malaysia, developed based upon the International Terrestrial Reference Frame (ITRF) 2000 or ITRF2000. One could argue that the quality of coordinates provided by MyRTKnet are less optimal as the latest realisation of ITRF at present is ITRF2014. This study aims to investigate the accuracy and precision of the resultant coordinates from MyRTKnet real-time services through a comparison with the control-quality coordinates from a network of post-processed data at some independent points for positioning purpose. Meanwhile for mapping purpose, the coordinates from Network Real-Time Kinematic (NRTK) at selected Cadastral Reference Marks (CRM) points were compared with their known values. The results show that the observed points in ITRF2000 move approximately 37 cm away from the points in ITRF2014 due to the constant movement of Sundaland Block. Meanwhile for the assessment of NRTK technique, there is no significant displacement for coordinates in ITRF2000 but ITRF2014 with the values of 4.4 and 39.8 cm at KDOJ point, respectively. The discrepancy in ITRF2014 could be due to the improper datum transformation procedure.

Abstract:

O IBGE-PPP, serviço de Posicionamento por Ponto Preciso (PPP) online, estima coordenadas originalmente referenciadas às materializações do ITRF (IGS) e então as compatibiliza para o SIRGAS2000 com a aplicação da transformação de Helmert e seus respectivos parâmetros de transformação. Em 17 de maio de 2020 o IBGE-PPP passou a utilizar um novo conjunto de parâmetros (P2), descontinuando o conjunto antigo (P1). Nesse contexto, este trabalho se propõe a avaliar os impactos dos novos parâmetros na compatibilização de referenciais e redução de coordenadas utilizados pelo IBGE-PPP, fundamentando-se em análise de séries temporais de dados de duas estações da RBMC, NAUS e AMCO. Analisando as séries temporais SIRGAS2000 compatibilizadas com P1 (SCP1) e P2 (SCP2) para as duas estações, observou-se que as séries de componentes norte (Δn) SCP1 apresentaram mudanças de nível (diferenças) de aproximadamente ±0,017 m e –0,013 m em relação a SCP2, nos períodos referentes às materializações do ITRF2005 (IGS05) e ITRF2014 (IGS14). As séries de componentes leste (Δe) e vertical (Δu) SCP1 também apresentaram diferenças quando comparadas à SCP2, porém com magnitudes entre 0,001 m e 0,006m e 0,004 m e 0,012 m, respectivamente. Considerando os conjuntos de parâmetros de transformação entre as materializações ITRF (IGS) e SIRGAS2000, pôde-se observar que as séries SCP2 apresentaram resultados mais consistentes quando comparadas às séries SCP1, diminuindo os impactos causados pelas trocas de referenciais ocorridas ao longo do tempo. Ademais, as séries SCP2 foram compatíveis com as séries referenciadas ao ITRF2014 (IGS) ao nível menor ou igual a 0,002 m.

Abstract:

La oficialización del marco CR-SIRGAS implica la necesidad de transformar la información vinculada al marco anterior a esta nueva referencia nacional. Se presentan los resultados de un análisis efectuado en la determinación de varios conjuntos de parámetros de transformación entre el antiguo marco geodésico CR05 y el marco geodésico CR-SIRGAS. Este proceso contempló el estudio de la transformación directa entre ambos marcos contemplando dos variantes, así como también, una secuencia de transformaciones igualmente en dos variantes considerando las soluciones ITRF que se han dado desde la implementación del CR05. Este proceso denominado transformación en escalera consideró la afectación que produjo el terremoto de Mw 7,6 en la península de Nicoya en agosto de 2012 [1] y [2] sobre los vértices de la red geodésica nacional activa y pasiva del CR05. Considerar los aspectos geométrico y físico es indispensable en una adecuada y correcta georreferenciación. Se usó el modelo de transformación baricéntrico [3] y [4] para seis parámetros: las tres traslaciones entre los orígenes y las tres rotaciones de los ejes [5]. En cada uno de los procesos de cálculo se analizaron los residuales en componentes topocéntricas [N, E, U]. Se ofrece como resultado dos conjuntos de seis parámetros de transformación desde el marco nacional CR05, época de referencia 2005,83, marco ITRF2000 al marco nacional CR-SIRGAS, época de referencia 2014,59, marco ITRF2008. Además, de dos conjuntos de seis parámetros entre CR05 y CR-SIRGAS contemplando diferentes soluciones ITRF y sus respectivas épocas. En cada determinación se expone el comportamiento de los residuales.

Abstract:

Os avanços das técnicas GNSS de alta precisão permitiram a diminuição das incertezas verticais dos levantamentos batimétricos, com uma melhor determinação do heave, do calado dinâmico e redução dos erros cotidais. Contudo, é necessário a determinação de um modelo de separação (SEP) entre o Datum da Carta Náutica (DCN) e o elipsoide de referência. Neste artigo será apresentada uma evolução histórica sobre o desenvolvimento de modelos SEP no mundo através de sete países: Estados Unidos, Canadá, Holanda, Arábia Saudita, Colômbia, Inglaterra e Brasil. O resultado das estratégias adotadas por países estrangeiros mostra incertezas de modelos SEP variando de 6,6 cm a 22,6 cm em relação ao ITRF. No caso do Brasil, é descrito um estudo pioneiro para o SEP da Baía de Guanabara, onde foi encontrada uma diferença média de 2,5 cm com um desvio padrão de 5,1 cm entre a superfície gerada com método de redução tradicional e por maré-GPS. Para uma cobertura nacional, é apresentado o projeto Alt-Bat, que prevê a utilização do geoide como referência vertical para os modelos hidrodinâmicos. Quanto às perspectivas, percebe-se um ciclo virtuoso para o desenvolvimento portuário: o investimento em dados ambientais, fornece uma maior acurácia de modelos SEP e menor incerteza dos levantamentos, propiciando maior calado, possibilidade do aumento no fluxo de cargas em portos e mais recursos para investimento. Por fim são apresentados os desafios a serem superados para a Hidrografia brasileira visando a determinação do DCN com uma acurácia de 10 cm em relação ao ITRF. Os modelos SEP são fundamentais para a integração de informações provenientes de diferentes referenciais verticais proporcionando uma navegação segura e gestão de processos costeiros.
