XAVIER, Emerson M. A.; ARIZA-LOPEZ, Francisco J. e URENA-CAMARA, Manuel A.. Automatic evaluation of geospatial data quality using web services. Rev. cartogr. [online]. 2019, n.98, pp.59-73. Epub 14-Mar-2022. ISSN 2663-3981. https://doi.org/10.35424/rcarto.i98.141.
The geomatics sector is going through a data overload scenario which new geospatial datasets are generated almost daily. However there are few or nothing information about the quality of these datasets, and they should be evaluated aiming to provide users some information about their quality. In this context we propose a solution for the automatic quality evaluation of geospatial datasets using the web services platform. This approach is compound by automatic evaluation procedures for quality control of topological consistency, completeness, and positional accuracy described in the Brazilian quality standard. Some procedures require an external dataset for comparison purposes. Hence we provide a set of synthetic datasets and apply over them an experimental design aiming to select suitable methods to find the correspondences between datasets. The solution has an interoperability tier that links users and automatic procedures using the standardized interface of Web Processing Service (WPS). Our results showed that the automatic procedure works very similar to the manual one.
