From Volunteered Geographic Information to Volunteered Geographic OLAP: A VGI Data Quality-Based Approach

open access: yes, 2014
Volunteered Geographic Information (VGI) represents a valuable source of information. At the same time this data presents new data quality issues such as credibility. In this paper, we investigate the integration of VGI in Spatial OLAP (SOLAP) systems, which allow analyzing huge volume of geographic datasets. By means of a real case study, we highlight
