Visual data aplication by examples of expertises in forensic ecotechnique: forest and trees and other forest evaluation projects
Introvičová, Sabina
The aim of the article is to compare aerial data usage in Forensic Ecotechnique: Forest and Trees (FEFT) present practice with current pictorial data processing technology. The method of visual data usage standardization is based on finding a unified process in data obtaining and data interpretation for particular types of expertises in terms of FEFT expertises typology. Forest evaluation by remote sensing is a non-destructive method which we can use in preserve natural areas, furthermore remote sensing offers possibility of the evaluation of a surveyed object that does not exist at the time of an expertise submitting.

Standardization of Remote Sensing Usage for Forensic Ecotechnique: forest and trees
Introvičová, Sabina ; Čermák, Jan (referee) ; Ulrich, Radomír (referee) ; Alexandr, Pavel (advisor)
The thesis presents the main points of standardization of remote sensing (RS) usage for Forensic Ecotechnique: forest and trees (FEft). Based on the study FEft expertise database, the types of expertise, which remote sensing data have already been used and the types where the use of remote sensing increases the exactness of solutions were analyzed. RS data are essential in a problematic situation when an examined object does not exist or has been changed at the time of the assignment. This situation may be solved by obtaining information about the investigated object via retrospective image data, as described in the model example. There are chosen categories of image data relevant to the needs of experts in this thesis. These categories of RS data and their products are described with an indication of their possible use in the expertise processing, including freely available or paid resources and archives of image data.

Land use GIS in a selected municipality
Sekanina, Michal ; Plánka, Ladislav (referee) ; Bartoněk, Dalibor (advisor)
The thesis content study of land use in municipality Lelekovice and its connection with software for geographic information system. It describes processing data especially historical cadastre maps, archival aerial imagery and orthophotos which were used for analyzing of this area. Analysis were performed in software ArcGIS. Appendixes of thesis are graphs and visualization of development of study area.

Porovnání metod zjišťování škod černou zvěří na porostech zrnové kukuřice firmy Agroservis Višňové
Krejčí, Miroslav
The first part of the thesis contains a literary review which sums up extracts from books and atricles from Myslivost magazine on the topic of wild boars' population and foraging ecology. Next part is devoted to the work on corn growths where the damage was evaluated. Three methods were used which determine the amount of damage in different ways. Then it was evaluated which of the methods is more accurate and more feasible. In the thesis all the methods are described in detail and evaluated. Moreover the benefits of preventive measures are valorized (growing corn in a certain distance from the wood and sowing a different crop plant around corn fields in order to facilitace shooting of wild boars).

Mapování současného stavu vegetace při horní hranici lesa na území NPR Praděd
Vršanová, Marie
The aim of the thesis was to derive complex information of the current vegetation cover in the alpine treeline ecotone in Praděd Reserve by using remote sensing. Particularly thesis focuses on an area and expansion of dwarf pine (Pinus mugo Turra) at site above the alpine treeline ecotone around the peak Praděd. Two types of aerial photograph from 2000 and 2012 and satellite images from Landsat 7 (yaer 2000) and Landsat 8 (year 2013) were used for mapping vegetation. Supervised and unsupervised classification accesses and also "per-pixel" and objected classification methods were used in image processing. All the classifications confirmed expansion of dwarf pine stands in the alpine treeline vegetation. Most precise method was based on supervised objected classification.

Historical development landscape in ORP Domažlice focused on forest areas, floodplain areas and residence areas
ŠPEIERL, Martin
This batchelor thesis is focused on mapping the historical development of forest, floodplain and residential areas in ORP Domažlice. This batchelor thesis was created in collaboration with the Planning Department in Domažlice. To assess the historical development is selected three time periods. 30s of the 19th century, when there was mapping Stable cadastre, next time period is 50 years of the 20th century, when there was taken aerial photography and last term, which represents the current state is 2011. For the 50s and 2011 are used aerial photographs in the form of orthophoto. Map data are georeferenced and vectorized in GIS environment. The acquired data is used to analyzed historical development and the creation of maps, tables and graphs.

Sledování sukcese dřevin po požáru s využitím leteckých snímků na lokalitě Havraní skála v NP České Švýcarsko
Krůček, Martin
This work explores the expansion of natural regeneration after the forest fire in the National Park Bohemian Switzerland, which occured in June 2006. Aerial photography were acquired in years 2009 and 2011 and both were used. The resulting accuracy achieved in the natural regeneration classification was 96 % in the year 2009 and 94 % in the year 2011. Natural regeneration covered 14% of the territory in year 2009 and in the year 2011 it was 51%. Furthermore comparison between the coverage of the natural regeneration and amount of individuals on the permanent research areas was made. The resulting correlation coefficient and coefficient of determination were low. The reason is, that the natural regeneration coverge detected using remote sensing is affected by dry crowns, high diversity of natural regeneration and also the absolute positional accuracy of aerial images.
