System for processing of GPS data from multiple mobile devices
Jurča, Josef ; Červenka, Vladimír (referee) ; Lattenberg, Ivo (advisor)
The aim of this thesis was to create an information system which consists of a mobile application, server and web application. Mobile application is designed for operating system Android and it is used for sending GPS coordinates of mobile devices to the server. These data are later processed by server and stored in database. Web application displays the current location of mobile devices in user group on a map, it also displays location history and statistics. Accuracy of the station location can be enhanced by using DGPS assuming that one of stations in a group does not change its location. The system was designed and then developed using modern web technologies and frameworks including PhoneGap, Ionic, Node.js, Express, MongoDB, Mongoose and AngularJS. Further measurements, that were performed, are supposed to present the effect of DGPS to location accuracy determination.

Mapping Time of Creation of Multimedia File to Position where It Was Taken
Jurča, Josef ; Rozman, Jaroslav (referee) ; Horáček, Jan (advisor)
The aim of the bachelor thesis is to create a web application which enables uploading and localization of photographs and video sequences and displaying them on the map. The position of photos is to be extracted from its EXIF metadata. If necessary information is not contained in the EXIF metadata, coordinates are to be assigned by use of external log from GPS receiver and the time of creation of the photo. Location of photo is to be displayed with use of the points on the map. The GPS coordinates are to be assigned to the video with help of external GPS log and time of last modification of the file. The application is to enable displaying actual position and route during video playback. The thesis also describes formats of multimedia data and its metadata, the GPS system and possible ways of using the system. Afterwards existing solutions of localization of multimedia data on the map are compared and consequently it is focused on design and implementation of the new application. The thesis also deals with the process of testing of the final application and summarizes its software requirements and limits. In conclusion achieved solution is evaluated and proposals of future progress of the application are made. The outcome of the thesis is functional web application which enables user to upload multimedia data and subsequently assign their position and display them on the map.
