Our research development on error and uncertainty modeling in spatial data and spatial analysis can be classified as the following stages: identifying the sources of uncertainties, describing errors in spatial data, quantifying error propagation in spatial analysis and finally controlling the quality of spatial data. This paper presents our study on quality control of spatial data. Quality cont...

The quality aspects of spatial data are very important in the decision-making process. However, the quality inspection of spatial data is still dependent on manual checking, and there is an urgent need to develop an automatic or semi-automatic generic system for spatial data quality inspection. In this paper, we present a general framework that automatically copes with spatial data quality insp...

Volunteered Geographic Information has provided a rich and valuable resource for spatial data in a variety of applications. Despite the many benefits, this information does not provide any guarantee for their quality. So far, there are several methods to determine the quality of VGI. In addition to introducing quality elements and their evaluation methods, the present study attempts to explore ...
