The OSM POI Analyzer project began by Alireza Kashian (Phd Student) in 2014 as a part of research project to develop advanced structures for analysing OSM data and understanding the underlying concepts of urban design. Discovering advanced methods for increasing the quality of geodata in OSM and confronting with vandalism was the primary goal of the project, but this goal gradually tuned into learning about positional accuracy of POIs which are important informational elements for users while they navigate and search for locations for their daily needs. Not only vicious activities in forms of vandalism can harm the quality of POIs but also small mistakes made by newcomers would result into a lower quality database. There are several reports that POIs are placed wrongly on the map and someone had to manually discover them and fix them. OSM POI Analyzer is a tool to discover the relationship between POIs and validate their Co-Existence and generates analytical reports which could be useful of researchers and advanced users to understand how these POIs are correlated.
