Resumo: Since the emergence and availability of a worldwide and free base of Digital Elevation Models (DEM), there was a significant increase of works for the accomplishment of the Earth surface modeling. However, the quality of the products generated from these data and the appropriate scales of use still lack more detailed studies. This work aims at analyzing the altimetric precision of data AW3D, SRTM and the IBGE's SPGEGGO50 Project in the Ribeirão São Domingos Hydrographical Basin (BHSD), in Catalão, Goiás, evaluating the adequacy of these data at 1:50,000, 1:100,000 and 1:250,000 scales, observing the methodology suggested for the Cartographic Accuracy Standard for Digital Cartographic Products (PEC-PCD). 44 points of control/validation were collected in field to the assessing of the models. For this purpose, the vertical tolerance and the mean square Error of the models in relation to the validation points were calculated. The SRTM and AW3D sensors and Project SPMGGO50 reached category "B" to the 1:100,000 and 1:250,000 scales.

De igual manera se observa que la calidad de los productos elaborados a partir de los datos y las escalas adecuadas de uso, todavía carecen de estudios más detallados. El presente trabajo se centra en analizar la precisión de los datos altimétricos de AW3D, SRTM y el Proyecto SPMGGO50 del IBGE en la cuenca de Ribeirão São Domingos, municipio de Catalão / GO, evaluando la posibilidad de realizar una adecuación de los datos a escalas 1: 50.000, 1: 100.000 y 1: 250.000, observando la metodología indicada por el Padrón de Precisión Cartográfica de los Productos Cartográficos Digitales (PEC-PCD). Fueron recogidos los datos de 44 puntos de control / validación en campo para la medición de los modelos. Por ende, se hicieron los cálculos de tolerancia vertical y el Error medio cuadrático de los modelos en los puntos de validación. Los sensores SRTM y AW3D y el Proyecto SPMGGO50 alcanzaron la clasificación para considerarse dentro de la clase "B" en escala 1: 100.000 y "A" 1: 250.000.A partir do surgimento e disponibilização de base de Modelos Digitais de Elevação (MDE) de abrangência mundial e gratuitos, houve um expressivo aumento de trabalhos para a realização da modelagem de superfície da Terra. Contudo, a qualidade dos produtos gerados a partir desses dados e as escalas adequadas de uso ainda carecem de estudos mais detalhados. O presente trabalho visou analisar a precisão altimétrica de dados AW3D, SRTM e do projeto SPMGGO50 do IBGE na bacia hidrográfica do Ribeirão São Domingos (BHSD), município de Catalão/GO, avaliando a adequação desses dados às escalas 1:50.000, 1:100.000 e 1:250.000, observando a metodologia indicada pelo Padrão de Exatidão Cartográfica dos Produtos Cartográficos Digitais (PEC-PCD). Foram coletados 44 pontos de controle/validação em campo para a aferição dos modelos. Para tanto, foram calculados a tolerância vertical e o Erro médio quadrático dos modelos em relação aos pontos de validação. Os sensores SRTM e AW3D e o projeto SPMGGO50 atingiram a classe “B” na escala 1:100.000 e “A” na escala 1:250.000.Universidade Estadual de Londrina2018-08-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos paresapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/geografia/article/view/3104510.5433/2447-1747.2018v27n2p87GEOGRAFIA (Londrina); v. 27 n. 2 (2018); 87 - 982447-1747reponame:Geografia (Londrina)instname:Universidade Estadual de Londrina (UEL)instacron:UELporhttps://ojs.uel.br/revistas/uel/index.php/geografia/article/view/31045/24122Copyright (c) 2018 GEOGRAFIA (Londrina)http://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessSantiago da Silva, AntonioRafael Pugoni Lopes Santiago, OberdanRibeiro da Silva, Claudionor2022-09-21T11:27:30Zoai:ojs.pkp.sfu.ca:article/31045Revistahttps://www.uel.br/revistas/uel/index.php/geografiaPUBhttps://www.uel.br/revistas/uel/index.php/geografia/oairevista.geografia.uel@gmail.com||marcar@uel.br||laudi@uel.br2447-17470102-3888opendoar:2022-09-21T11:27:30Geografia (Londrina) - Universidade Estadual de Londrina (UEL)false
