英文摘要: This paper reports on the advantages and disadvantages of motor-glider use in studying topoclimates.Despite the widespread use of images taken from low-altitude flying platforms (planes, helicopters,UAVs), the use of a motor-glider for imagery collection has not been reported in environmental stud-ies. In presented study, the low-altitude remote sensing techniques were used to increase the spatialresolution of thermal maps derived from Landsat ETM+ thermal bands. Thermal images from motor-glider were taken by a thermovision camera. At the local scale, land surface temperature (LST) is oneof the factors influencing topoclimatic diversity hence, by analysing LST distribution one can determinetopoclimatic variability. Topoclimate has been the subject of previous studies, however, they have notused thermal remote sensing in the research process but instead relied on ground measurement network.The presented research contributes to better understanding of the thermal environment of the Earth byemploying an innovative data collection method suitable for relatively large areas under specific weatherconditions. The data collection with motor glider offers good spatial resolution of less than 1 m and facil-itates the compilation of good quality LST maps. The paper discusses the influence of spatial resolutionon LST variability and demonstrates gain in information granularity resulting from sub-meter resolutionof collected data. © 2014 Elsevier B.V.
