Selected Multimedia Tools as a Tool to Compare Changes in the Landscape

Abstract

Remote sensing is one of the most widely used methods of acquiring spatial data describing the Earth's surface, which is associated with subsequent data analysis and processing. Most often, the imagery was obtained using an aeroplane or satellite as a sensor carrier, but due to technological advances, unmanned aerial vehicles (UAVs) are increasingly used. UAVs provide very-high spatial resolution data. Multimedia tools are essential during the whole processing and visualization procedure. The paper demonstrates that UAV-borne RGB data can be successfully used to detect water surface, bare land and vegetation as key land cover types. Both supervised and unsupervised classification methods are used.
