Název v původním jazyce

Use of digital aerial photography for sub-alpine vegetation mapping: A case study from the Krkonoše Mts., Czech Republic

Popis výsledku v původním jazyce

Multispectral aerial photographs from 1986, 1989 and 1997 were used for mapping and assessment of changes in sub-alpine vegetation of the Krkonoše Mts Plateau (1300 to 1400 m a. s. l.), Czech Republic. Scanned aerial photographs were digitally processedby various remote sensing methods. The results were geometrically corrected by registration into orthophoto images. In comparison to the field survey, aerial photography provided less detail and vegetation was characterized mostly by dominant species. The approach failed to map small patches of heterogeneous or atypical vegetation and to differentiate vegetation types with dominants of similar appearance. Nevertheless since this method is comparably less time- and labour-consuming, it seems suitable formapping distinct vegetation types, surveying larger areas and identifying changes over time.
