Priprava podatkov za prikaze na interaktivni mizi : diplomska naloga

Omić, Elvira (author), Oštir, Krištof (mentor), Tekavec, Jernej (comentor)

Diplomska naloga se osredotoča na proces priprave in predstavitve prostorskih podatkov na interaktivni mizi, ki deluje za aplikacijo ESA Vayu TT. V nalogi so opisani postopki pridobitve in obdelave satelitskih posnetkov, vključno z uporabo QGISa in vtičnika Semi-Automatic Classification Plugin za izračun NDVI indeksa in sestavo večspektralnih posnetkov. Analizirani so učinki požara na Krasu iz leta 2022, pri čemer sem ustvarila prikaze za obdobja pred in po požaru. Uporaba NDVI indeksa omogoča oceno sprememb v vegetaciji, kar razkriva vpliv požara na ekosistem. Aplikacija ESA Vayu TT se je izkazala kot učinkovito orodje za interaktivno prikazovanje podatkov, čeprav se pri večjem številu prikazov pojavi zmanjšana preglednost. Na koncu naloge so navedena priporočila za izboljšanje uporabe interaktivnih prikazov in predlogi za prihodnje raziskave ter širšo uporabo aplikacije v strokovnih področjih, kot so geoinformatika in upravljanje naravnih virov.

Abstract

The thesis examines the methodology for preparing and visualizing spatial data on an interactive display, employing the ESA Vayu TT application. The work outlines the steps for processing satellite images, including applying QGIS and the Semi-Automatic Classification Plugin for computing the NDVI index and generating multispectral images. The study evaluates the impact of the 2022 wildfire in Kras region by creating visual representations for the periods before and after the fire. Utilizing the NDVI index facilitates the analysis of vegetation changes, highlighting the fire's influence on the environment. While the ESA Vayu TT application has proven effective for interactive data presentation, more visualizations can lead to decreased clarity. The thesis concludes with insights on enhancing the use of interactive displays. It offers recommendations for future research and applications of the software in fields such as geoinformatics and natural resource management.
