Object Database Spatial Extension
Polách, Ondřej ; Křivka, Zbyněk (referee) ; Rychlý, Marek (advisor)
Still increasing requirements are made on database systems, because users need to work with still more complex data. Because of the historical development of database systems, post-relational database systems are mainly used today. As follows from their name, post-relational database systems are built on relational database systems and expand them so that they are able to work with complex data. The vast majority of today's spatial database systems is based on post-relational databases. However, this work is trying to find a connection between object and spatial databases. The obtained knowledge is reflected in the implementation of the object database spatial extension.

Design of an application for the visualization of geographic data documenting the development of defunct landscapes
Nekola, Lukáš ; Čábelka, Miroslav (advisor) ; Laštovička, Josef (referee)
This thesis deals with the design and subsequent creation of a 3D map application for visualization of geographic data documenting the development of the landscape in the cadastral area of Holešice. The added value is the creation of different variants of spatial SQL queries for the representation of changes in elevation and land use in the form of polygons. In the first part, the available technologies for the creation of the application are properly described together with the basic algorithms enabling the creation of polygons. The practical part starts with the preparation of a dataset of points created by data fusion representing the height division, which was stored with other data in a spatial database. This is followed by the creation of the application itself based on the proposed client-server architecture. The principle is to store the output of one of the queries in the form of a materialized view. Map service based on the query is created in GeoServer technology and displayed in the CesiumJS library. The specific choice of the output and the selection of the query variant depends on the submission of the form by the user. Key words: spatial database, 3D visualization, map application, defunct landscapes, Most region, web

GEO Information System for Passportization and Visualization of Wide Computer Networks
Fibich, Ondřej ; Burget, Radek (referee) ; Kolář, Dušan (advisor)
The thesis is focused on the problem of the passportization and the visualization of wide computer networks with the usage of geographic information systems. It discusses principals and properties of geographic information systems and spatial databases that are frequently used as data carriers for geographic information systems. The main part of the thesis is dedicated to the passportization of computer networks with focusing on the physical network structure. After the definition of the passport format the thesis continues with the analysis, the proposal, the implementation and the testing of the geographic information system for managing and visualization of the passport in this format. The thesis is ended by a case study that demonstrates the passportization process of an access computer network in the implemented system.
