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.

Using the unmanned technology for determining the drainage systems and their failures on the agriculturally managed soils
FÜRST, Vojtěch
Objective of this dissertation was to study possibilities of detection of subsurface drainage systems by unmanned aerial vehicles. Unmanned aerial vehicles, "drones", served to military purpose in the past. Nowadays these unmanned aerial vehicles helps to map drainage on fields because it is hard to get draining plans today and a big part do not match with the actual implementation of drainage systems. We can also add that nobody cares about drainage today. Drainage drains of soaked soil and improve its harvest. Drainage facilitates transport of nutrients (nitrogen and phosphorus) to watercourses. Fields changes over time to parcels. There is description of sorting and functionality of drainage systems as well as description of malfunctions and used material in theoretical part. There is also description of unmanned aerial vehicles and a method of detection of subsurface drainage systems . Besides there is detailed description of the locality, function of drainage system and evaluation. There is description of indication of drainage on specialized aerial photography. Indications are compared with period plans. Methods of highlighting indications are applied and evaluated by programs Agisoft PhotoScan Professional and Arc GIS 10.1. Main results are photographies that demonstrate location of drainages. Using ground control points the image converted into the coordinate system.

Key steps in standardization of aerial photography (remote sensing) usage for forenzic ekotechnique: forest and trees needs
Introvičová, Sabina
The description of key steps for remote sensing data usage as base data for forensic ecotechnique expert opinions is a topic of the article. In accordance with systematic methodology in forensic ecotechnique, all accessible information about an object of examination should be employed. It follows that remote sensing data usage for expert opinions working out in the field of Forensic ecotechnique: forest and trees is necessary. Remotely sensed data was divided into three categories: aerial photography, radar imaginary, and satellite data; all with basic characteristics. The main problem of the standardization of remotely sensed data usage is in its dynamic development which has an impact of conditions for obtaining the data from different subjects dealing with pictorial data processing.

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.
