Differential GPS
Lebó, Denis ; Hrubý, Martin (referee) ; Rozman, Jaroslav (advisor)
My thesis studies the navigational technology for determining the current location of an object -- differential global navigational system (DGPS) with real-time kinematic (RTK) enhancement. The use of this technology is calculating the position of an object in real-time using two GNSS recievers. These recievers are used to acquire positional information from GNSS satellites (GNSS technology), which is then made more precise by the exchange of information between the recievers(DGPS/RTK technology). The thesis also provides a way to visualize the acquired location and provides a channel of communication for the GNSS recievers using the internet. The channel of communication will be provided by the program SNIP made by SubCarrier Systems. The correctional data from the GNSS recievers will be transmitted using the NTRIP (Network Transport of RTCM via Internet Protocol) protocol. For the creation of the website the web application framework Flask, written in Python, was chosen. For the visualization of the acquired location the Mapy.cz platform with use of the application programming interface developed by Seznam.cz for this platform -- Mapy API was chosen.

Coordinate System Conversion Options for Web Application
Fiala, Marek ; Michal, Bohumil (referee) ; Kašpárek, Tomáš (advisor)
The aim of this work is to find and compare tools and libraries for conversion of coordinates between Coordinate System WGS84, S-JTSK, UTM zone 33N and Pseudo-Mercator, which could be used in Web Application. Found options are then tested with focus on speed and accuracy of conversion. The main result of this work is list of usable possibilities for coordinate system conversion including comparison of performance and accuracy and its advantages and disadvantages.

Analysis of real estate market using information on Internet
Bulín, Martin ; Zeman, Václav (referee) ; Komosný, Dan (advisor)
This thesis was created as a helping tool to estimate the price of properties by comparative method, which needs a database of properties. This database is created by a program. The main aim of this thesis is to create an application in Python language, which will search through contents of websites of a chosen real estate portal in Czech Republic. The next aim of this thesis is to create program which will search for real estate according to chosen criteria. The purpose of these criteria is to compare and estimate the price of properties. In the theoretical part of this thesis I will describe data mining and architecture of data mining. In the practical part I will design an aplication and in the end I will implement it. This aplication will go through websites and obtain data about real estate offices, their advertisements and photos of advertisements. For easier work with the output file that contains the advertisements, I created an application for searching individual advertisements based on users specification. This program allows to quickly search for the requested data from the output file. These data are subject to further work, it is possible to analyse them and create interesting statistics and maps.
