Support for Spatial Data in Oracle
Volf, Tomáš ; Chmelař, Petr (referee) ; Zendulka, Jaroslav (advisor)
This work acquaints with support for working with spatial data and mentions the possibility for spatio-temporal data in the Oracle database server 11g. On the basis of acquaintance with support for spatial data was designed sample application that uses this support. The sample application provides to display spatial data, which are stored in the database, graphically and also displays information about spatial objects. Finally, there are reviewed achievements and the possibilities how to continue in the project.

Automatic detection of driving lanes geometry based on aerial images and existing spatial data
Růžička, Jakub
The aim of the thesis is to develop a method to identify driving lanes based on aerial images and existing spatial data. The proposed method uses up to date available data in which it identifies road surface marking (RSM). Polygons classified as RSM are further processed to obtain their vector line representation as the first partial result. While processing RSM vectors further, borders of driving lanes are modelled as the second partial result. Furthermore, attempts were done to be able to automatically distinguish between solid and broken lines for a higher amount of information contained in the resulting dataset. Proposed algorithms were tested in 20 case study areas and results are presented further in this thesis. The overall correctness as well as the positional accuracy proves effectivity of the method. However, several shortcomings were identified and are discussed as well as possible solutions for them are suggested. The text is accompanied by more than 70 figures to offer a clear perspective on the topic. The thesis is organised as follows: First, Introduction and Literature review are presented including the problem background, author's motivation, state of the art and contribution of the thesis. Secondly, technical and legal requirements of RSM are presented as well as theoretical concepts and...
