Extrakce linie stoku vody z rozptýlených dat

Abstract

Diploma thesis deals with extraction of a line, which represents stream line on the surface. Line is extracted from diffuse data, which are created by applying Monte Carlo method on process of computing the flow accumulation. At the beginning, work deals with explanation of uncertainty. Next parts of work consist of issues with generating diffuse data and explanation of Monte Carlo method. After that work deals with extraction of stream line itself. It describes tested methods, functions and their usability. It also consists of design and description of created procedures which lead to extraction of stream line from diffuse data. The end of the work consists of comparison of created procedures and evaluation of achieved results.
