The Geomatics Synthesis Project 2014 consisted of three seperate projects, this poster is about the GeoFort project. The aim of this project was to make the visitors of the ‘GeoFort GeoExperience’, an educational attraction in the field of Geo-Information, aware of passive WiFi tracking and inform them about the possibilities of this technique. Two deliverables were created for this purpose, the first a map of the location of all devices on the island in (near) real time and the second a map with the track an individual visitor has walked over the island. The data was collected using the method of passive WiFi tracking. For this, BlueMark innovations provided us with scanners. These scanners are passive, this means that they only read the signals send out by WiFi enabled devices. Every WiFi enabled device sends out a signal every so often, this signal consists of information about the device and information about known networks from the device. This signal is then picked up by the BlueMark scanners. With the signal and the location of the scanners, the location of the device can be calculated. This information is presented via a webpage, where two different maps are available. The first map is a map of the GeoFort with the last location of all the devices that are present on the island. This map has a delay of five minutes due to processing time. The second map is a map of the GeoFort with the path of the visitors that are in the project room at that time, on this path, a marker is ‘walking’ in the same order the visitor has walked. There are also two posters created that explain the technique and the possibilities of the technique. During the project, research has been done on other localisation techniques and on the role of privacy regulations in this project.
