Resumo: Technological advances and web 2.0 have enabled any individual with access to the internet to generate geospatial data on Voluntary Geographic Information platforms. Given the speed with which these data are obtained and the differences regarding the reference mappings present in research from different countries, which has investigated the quality of their features in order to establish viability in integration processes. This work evaluated the quality of features from the OpenStreetMap platform (OSM) through positional accuracy, thematic accuracy and completeness indicators, with the city of Salvador-BA as a study area to obtain the potential in its use. The methodological steps included the selection of the categories: size and arrangement of the samples in the study area, measurement and attributes filtering with repeated information, comparative analysis based on aforementioned indicators, spatialization and results analysis. Through the positional accuracy results it can be said that the scale ranged from 1: 20,000 to 1: 30,000 and in other indicators the main errors sources are associated with the empty fields existence and in the topological structure of linear features differences. The evaluated features are promising for use of this type of data, however studies on the data heterogeneity need to be deepened.

Considerando la rapidez con que estos datos pueden ser obtenidos y las diferencias relacionadas al Mapa de Referencia, estudios en diferentes países han investigado la calidad de sus características, con el objetivo de establecer la viabilidad en proceso de integración. En el contexto presentado, este trabajo tiene como objetivo evaluar la calidad de las características provenientes de la plataforma OpenStreetMap (OSM) respecto a los indicadores de Exactitud Posicional, Exactitud Temática e Integridad, en un área urbana de Brasil (Salvador-BA) y así obtener las potencialidades en su utilización. Las etapas metodológicas comprenden la selección de las categorías, tamaño y disposición de las muestras en el área de estudio, sus medidas y filtrado de atributos con informaciones repetidas, análisis comparativos a partir de los indicadores citados, especialización y análisis de los resultados obtenidos. Se identificó que en la exactitud posicional la escala varia de 1:20.000 hasta 1:30.000 y que en los demás indicadores la principal fuente de error está asociada a la existencia de campos vacíos y diferencias en la estructura topológica de las características lineales. Las características evaluadas se muestran promisoras desde que sean intensificados los estudios sobre la heterogeneidad de los datos.Os avanços tecnológicos e a web 2.0 possibilitaram que qualquer indivíduo com acesso à internet possa gerar dados geoespaciais em plataformas de Informação Geográfica Voluntária, dada a velocidade com que estes dados são obtidos e as diferenças quanto aos mapeamentos de referência presentes em pesquisas de diferentes países, as quais tem investigado a qualidade das suas feições no intuito de estabelecer viabilidades em processos de integração. Este trabalho avaliou a qualidade de feições oriundas da plataforma do OpenStreetMap (OSM) através dos indicadores de acurácia posicional, acurácia temática e completude, tendo como área de estudo a cidade de Salvador - BA para obtenção do potencial na sua utilização. As etapas metodológicas compreenderam a seleção das categorias: tamanho e disposição das amostras na área de estudo, mensuração e filtragem de atributos com informações repetidas, análises comparativas a partir dos indicadores citados, espacialização e análise dos resultados. Através dos resultados da acurácia posicional pode-se afirmar que a escala variou de 1:20.000 até 1:30.000 e nos demais indicadores a principal fonte de erros está associada a existência de campos vazios e diferenças na estrutura topológica de feições lineares. As feições avaliadas mostram-se promissoras para utilização deste tipo de dado, porém estudos quanto a heterogeneidade dos dados necessita ser aprofundado.Universidade Estadual de Londrina2021-06-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos paresapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/geografia/article/view/4176810.5433/2447-1747.2021v30n2p255GEOGRAFIA (Londrina); v. 30 n. 2 (2021); 255 - 2752447-1747reponame:Geografia (Londrina)instname:Universidade Estadual de Londrina (UEL)instacron:UELporhttps://ojs.uel.br/revistas/uel/index.php/geografia/article/view/41768/29765Copyright (c) 2021 GEOGRAFIA (Londrina)http://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessElias, Elias Nasr NaimFernandes, Vivian de Oliveira2022-09-20T13:45:20Zoai:ojs.pkp.sfu.ca:article/41768Revistahttps://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:2022-09-20T13:45:20Geografia (Londrina) - Universidade Estadual de Londrina (UEL)false
