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.

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.

Remote sensing data usage for solving of illegal permanent stands cut down issues
Introvičová, Sabina ; Hájek, Filip
It is possible to use remote sensing data for Forensic Ecotechnique: Forest and Trees expert’s assessment processing. The image data from some satellites are free on line at present time. Also electromagnetic bands numerical depiction can be obtained from the on line satellite imagery using the open source GIS Viewer QGIS. The way of remote sensing data usage for forensic experts is shown on an example of expert’s assessment regarding the cut down forest. A significant change in forest cover is possible to find when two Landsat-8 satellite images acquired at the different time are compared. We are able to obtain the height of the cut trees from the normalized Digital Surface Model. The height is a quantity needed for the cut trees reconstruction.

Status quo and development trends of remote sensing usage for forensic ekotechnique: forest and trees
Introvičová, Sabina ; Janata, Přemysl
This paper refers to possibility of Unmanned Aerial Vehicle (UAV) usage for FEFT experts’ needs. Different Remote Sensing Stations (Czech Geological Survey, Forest Management Institute and others) obtain Czech territory actual pictorial data from satellites together with aerial images, LiDaR data from Ministry of Agriculture, Ministry of Defense and Czech Office for Surveying Mapping and Cadastre (COSMC) joint project that deals with regular two years scanning of the Czech Republic. Remote Sensing Stations also have resources for obtaining actual aerial photographs of investigated objects and localities through commercial subjects operating own airplanes. State organizations initiating expertise do not have resources for actual scanning of the investigated localities with airplanes. Forensic experts depend on COSMC products. COSMC is the only one of the organizations dealing with Czech territory scanning which has authority to sell actual aerial images if are available. Remote-controlled UAVs can aboard equipment for remote sensing. UAVs service expenses are many-times lower than aircraft service expenses. Department of Geoinformation Technologies at Mendel University Brno has a multirotor UAV available that is equipped to gain optical and infrared band data.
