Evaluation of suburbanization in Prague's hinterland - influence on landuse and on territory function.
Bromová, Petra ; Kupková, Lucie (advisor) ; Potůčková, Markéta (referee)
Evaluation of suburbanization in Prague's hinterland - influence on landuse and on territory function The main goals of this thesis are to describe land use changes in three time periods in cadastral units Dobřejovice, Modletice and Jažlovice situated in Prague's hinterland, to evaluate their influence on the territory function and to create a database of commercial objects in this area. There is a theme introduction in the first part. Furthermore, the thesis describes methods used for the data processing. The main part of the thesis is focused on the characteristic of the area of interest and describes the detected land use and territory function changes based on spatial overlays of time series of very high- resolution image data. The outputs of this work are maps of land use in 1994, 2004 a 2007, maps of land use changes in the particular time periods and the database of the commercial objects with their utilization purpose.

Analysis of forest canopy density based on textural features of hight resolution imagery and airborne laser scanning data
Bromová, Petra ; Potůčková, Markéta (advisor) ; Hájek, Filip (referee)
Analysis of forest canopy density based on textural features of high resolution imagery and airborne laser scanning data Abstract The objective of this thesis is to assess the forest canopy density in the Šumava Mountains, Czech Republic. The spruce forests in this area have been suffering from the bark beetle outbreak for almost 20 years resulting in a mixture of dead and young trees, mature forest stands and peat bogs. The canopy density was evaluated using a very high spatial resolution panchromatic imagery and low point density LiDAR, combined with an object oriented approach. The classification based on three GLCM texture measures (contrast, entropy and correlation), which were derived from the image objects, resulted in a kappa index of accuracy of 0.45. Adding the information from the LiDAR data, the accuracy of the classification improved up to 0.95.
