Exploring the Possibility of Semi-Automated Quality Evaluation of Spatial Datasets in Spatial Data Infrastructure

Abstract

Abstract. Over the past decades, World Wide Web technology has developed greatly. One of the most important outcomes of this technology is to share data in a worldwide domain. A considerable amount of available data have spatial components and are hence called spatial data. The level of quality that spatial datasets conform plays an important role in their reliability for use in projects. This research aims to overview spatial data quality elements and select appropriate elements suitable for means of semi-automated quality evaluation. In this paper, the ISO 19100 series of standards for geographic information is used as basis for quality evaluation. The possibilities of use of different spatial data quality elements for semi-automated quality evaluation are explored and discussed. Finally, based on argumentation and reference to other research studies, a list of spatial data quality elements and sub-elements suitable for semiautomated quality evaluation of spatial datasets are presented.

Different Remote Sensing Data in Relative Biomass Determination and in Precision Fertilization Task Generation for Cereal Crops

“…There are some general applicability studies, such as Mobasheri (2013), which applied spatial data quality standards to study automatization possibilities for quality evaluations of geo-graphic datasets, and Wang and Huang, (2007) which used earlier standards and presented a methodology for representing data quality rules. He at al.…”

QualEvS4Geo: A peer-to-peer system architecture for semi-automated quality evaluation of geo-data in SDI

“…In a recent research study [4], the possibility of semiautomated quality evaluation of geo-datasets have been explored. Different data quality elements and sub-elements have been considered and a survey of existing techniques for quality evaluation based on the selected data quality element has been performed.…”

“…As an initial step, research studies for exploring the possibility of geospatial data quality evaluation has been carried out [4]. Several evaluation methods, techniques and pieces of softwares are already available that have the potential to be used for quality evaluation.…”

Web Service for Positional Quality Assessment: The WPS Tier

“…Despite the simplicity of the quality procedure, just an overlay of previously tagged data with some quality elements, this study seemed to be the first attempt of an automatic evaluation service in the literature. A more recent study also indicated the quality evaluation can be executed through a WPS (Mobasheri, 2013).…”
