Abstract :People can mark places they visit and share them with other people with using geospatial online social networks. Discovering socially popular locations on geospatial social networks became more important for many applications such as public transportation system planning, tourist trajectory planning etc. In the literature, there are some studies conducted for this purpose. However, most of these studies focused on only location information and ignored time data of check-in. In this study, we analyzed geospatial social network data by dividing it into time slots. Also, the vast majority of studies in the literature do not provide visual analysis results. This reduces the intelligibility of the results. Our system uses advanced heat maps to provide easy visually interpretable results. The developed system determines the tendency of the check-in intensities at the time of day and the seasons of the year. Using QGIS, which is an open source geographic information system, we obtained check-in data from dataset within Turkey country boundary. Also, Istanbul province’s check-in data was used for more specific analyzing with 3-hour ranges of a day. Furthermore, the density of spatial check-in points was obtained by using heat maps.
