Generation of an orthophoto from close range aerial images in the area of Sečovlje salina nature park

In the last few years new technologies have allowed wider use of unmanned aerial vehicles (UAV) for spatial data acquisition. For the purpose of this thesis the UAV was used as a platform to photograph the area of Sečovlje salina nature park. From the acquired images an orthophoto mosaic of the area was produced. The client needs this orthophoto as a raster layer in GIS in order to make further analysis. This thesis describes and outlines the used UAV and the related computer program required for the planning and acquisition of close range aerial images. After completing the fieldwork, the thesis focuses on processing the acquired data and producing a final as well as for the client in semantic terms improved orthophoto. The results were evaluated by analyzing the impact of particular influences on the quality of the final product. Conclusions are given in the final part of the thesis
