- The area under investigation described in this paper is located in the Outer Carpathians in the western part of Beskid Wyspowy mountain ridge, in the Rača Subunit of the Magura Nappe and partly in the area of Tectonic Window of Mszana Dolna. A purpose of the study was to use of aerial photographs for assessment of readability of geological structure of above mentioned area. There is a lot of factors that determine the readability of geological structure on air photos: scale of the photographs, kind of films and filters, treatment of negatives and positives, season and time of the day when the photos were taken. The following photo interpretation criteria were considered the greatest importance during interpretation of the geological structure: morphology, tone of the air photos, colour, objects‘ size and shape, image pattern and shade. Also a hydrographical network and vegetation cover were taken under consideration as they are strongly connected with the geology. A geological sketch was executed as a result of the study. The sketch was compared with geological maps. It turned out that there are a few geomorphological elements that could be recognised in air photos as valleys, mountain’ chains, rivers’ terraces and landslides. There was no problem with distinguishing such geological structures as: intersectional lines, lithology, bedding of rocks, faults, the boundary of the Magura Nape’s thrust. In some cases there was incompatibility between elaborated geological sketch and geological maps due to a way the map was prepared, dislocalization of an element on the geological map, and problems with an interpretation of the areas with an abundant vegetation.
