Use of Spatial Visualization Techniques in Analyzing Customer Transaction Data in Banking Industry

Spatio-temporal data analysis has gained a growing degree of importance with the emergence of sensor technologies and applications that collect location data. This talk will introduce an interactive tool that effectively visualises spatio-temporal data using two-dimensional data clustering heatmaps along with temporal histograms. The presented methodology creates grid-based heatmaps, and calculates pairwise similarity scores of map images to help detect recurring patterns. The tool is employed in analyzing a GSM friend-finder subscriber activity data and a bank credit card transaction data. Examples of patterns are reported that are not observable from the tabular data, but easily observable using the tool.
