In the planning of measures of environmental protection, it is important to detect or locate, for example, the most valuable natural sites for several species, the best habitats for some particular species, or the source areas of nutrient emissions into waterways. Remote sensing data sets and other spatial or geographic information facilitate the studying of these phenomena if suitable computational methods are used for analyzing them. In our research, we acquire by UAV, collect from national data sources, process and analyze these kinds of spatial data sets and try to promote the minimization of harmful environmental impacts in land use planning situations.
