The position of the products from the images recorded with a remote-controlled aircraft is influenced by the configuration of the photogrammetric block. In the course of the task, the Gmoznica Bistrica area was established by the geodetic network of points, which represent the offset and checkpoints in the compensation of the photogrammetric block. The area was recorded at different heights and using transverse flights. From the acquired images we have composed different photogrammetric blocks, formed with a combination of images recorded at different heights and in different directions of the year. The accuracy of photogrammetric blocks is estimated on the basis of differences on checkpoints. In addition, by comparing the existing data, the change in the volume of the material on the landfill is estimated.
