magistrsko delo
Abstract
Termalni satelitski posnetki prikazujejo termično sevanje zemeljskega površja in so uporabni na
mnogih področjih. Njihova prednost je, da je zajem podatkov brezkontakten, celovit in periodičen, kar
omogoča časovno primerjavo podatkov. V tej nalogi smo s termalnimi satelitskimi podatki opazovali
jamske vhode. V prvem delu naloge so predstavljeni program Landsat in značilnosti satelita Landsat 8.
Postopek določitve temperature tal s satelitskimi termalnimi posnetki je opisan na splošno in za
različne rabe tal. Kraške jame imajo posebno mikroklimo, ki je odvisna od mnogih dejavnikov.
Opredelili smo značilnosti jamskih vhodov, ki so pomembne za potrebe magistrske naloge. Drugi del
predstavlja praktični del naloge, kjer so izbrani primerni jamski vhodi in termalni satelitski posnetki. S
slednjimi smo opazovali temperaturo jamskih vhodov glede na njihovo okolico v obliki dveh
pravokotnih prečnih profilov. Zaradi spremembe jamske klime med različnimi letnimi časi smo
opravili obdelave poletnih in zimskih posnetkov. Analiza rezultatov je pokazala, da je pri nekaterih
jamskih vhodih mogoče opaziti temperaturno anomalijo, a bi to lahko povezali tudi z reliefom. Pri
veliki večini jam ni opaziti pričakovanih temperaturnih razlik.

Secondary title: |
Observing cave entrances with thermal satellite data |
Secondary abstract: |
Thermal satellite images show thermal radiation of Earth's surface and are useful in many fields. Their
advantage is that the data capture is non-contact, comprehensive and periodical, which enables
comparing the data through time. In this master thesis we observed cave entrances with thermal
satellite images. First part of thesis presents the programme Landsat and characteristics of the satellite
Landsat 8. Process of ground temperature determination is described in general and for different land
usage. Karst caves have special microclimate which is dependent of many factors. We defined the
characteristics of cave entrances that are important for this master thesis. Second part presents
practical work where we have chosen suitable cave entrances and thermal satellite images. With the
latter we observed temperatures of cave entrances compared to their surroundings and created two
perpendicular cross profiles. Because cave's climate change through the year, we processed summer
and winter images. The analysis of results shows that there at some cave entrances there is a
temperature anomaly. But that can also be related to the relief. At most cave entrances there are no
temperature differences which we expected. |
