Best Paper 2021
The U.V. Helava Award, sponsored by Elsevier B.V. and Leica Geosystems AG, is a prestigious ISPRS Award, which was established in 1996 to encourage and stimulate submission of high quality scientific papers by individual authors or groups to the ISPRS Journal of Photogrammetry and Remote Sensing, to promote and advertise the Journal, and to honour the outstanding contributions of Dr. Uuno V. Helava to research and development in photogrammetry and remote sensing.
The Award is presented to authors of the best paper, published in the ISPRS Journal during the four-year period. The Award consists of a monetary grant of SFr. 10,000 and a plaque. For each year of the four-year evaluation period, the best paper is selected, and among these four papers, the one to receive the U.V. Helava Award is selected.
The Jury appointed by the ISPRS Council evaluated papers from volumes 171-182 (2021) and announces its decision for the Best Paper. The winner of the 2021 Best Paper Award is:
