Even in this age where sensors are abundantly available, situational awareness (SA) is far from certain. The objective of this study is therefore to investigate the potential of geospatial video tracking application to enhance SA. Two research questions were formulated focusing respectively on the performance and on potential use cases of geospatial video tracking. To test the performance both a single and multi-camera video tracking application were developed and evaluated based on the CLEAR method (Bernardin and Stiefelhagen 2008). For evaluation purpose the Performance Evaluation of Tracking and Surveillance (PETS) 2009 dataset was used. The found accuracy for the multi-camera video tracking application is 65% lower than the standard single camera tracking application. Found tracking precision of the multi-camera video tracking application is 8.5% higher compared to the single video tracking application. Secondly an expert survey was performed to gather more insight in potential use cases for geospatial video tracking. The performed expert survey clearly indicates numerous applications in which geospatial video tracking could contribute. Overall it can be concluded that geospatial video tracking has a significant potential, but needs serious improvements before it can be used in practice. A number of improvements are provided for further research.
