For the monitoring of ecologically valuable areas, terrestrial measurements and a precise actual thematic map are needed. For the creation of this, several methods can be used. In less accessible or inactive areas, remote sensing or aerial methods are suitable. For remote measurement, they are satellite data, aerial data or Remotely Piloted Aircraft Systems (RPAS) data respectively. The satellite data has sub meter geometric resolution (50cm per pixel), aerial data in decimeters; both data types are often too expensive or designed for larger areas. RPAS have a geometrical resolution of about a cm and can be used for small areas in one flight only, but from an economical point of view, it is low cost and environmentally friendly. This contribution deals with the use of unmanned aerial vehicles in cartographic tasks. The eBee drone system that is introduced in this paper is used for mapping specific tasks. The problems of planning, data acquisition and processing are illustrated by the creation of orthophoto and NDVI. The theoretical preparation of data acquisition deals with mission planning and operation. “Božídarské rašeliniště” moorland is a national nature reserve in the district of Karlovy Vary, the largest area in the Ore Mountains. It is located west of the city of Boží Dar at an altitude of 940 to 1,115 meters. Peat extraction took place here until the Second World War. The protection of this natural area was declared in 1965 over an area of about 1000 hectares. The laboratory of photogrammetry at the Czech Technical University in Prague (CTU) monitored this area to obtain comprehensive databases for ecologists, biologists and municipalities (touristic access and activity planning) as a case project.
