Best Paper 2019
The U.V.  Helava Award, sponsored by Elsevier B.V. and Leica Geosystems AG, is a  prestigious ISPRS Award that 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, written in English and published  exclusively in the ISPRS Journal of Photogrammetry and Remote Sensing during  the four-year period from January of a Congress year, to December of the year  prior to the next Congress. The Award consists of a monetary grant of SFr.  10,000 and a plaque. A five-member Jury, comprising experts of high scientific  standing, whose expertise covers the main topics included in the scope of the  Journal, evaluates the papers. 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 will be selected. 
  The U.V.  Helava Award will be presented at the 24th ISPRS Congress in Nice,  France, 4-10  July 2021. The Jury appointed by the ISPRS Council, evaluated  papers from volumes 147-158 (2019) and announces its decision for the Best  Paper. The winner of the 2019 Best Paper Award is: 
 
 "Design and evaluation of a full-wave surface and bottom-detection algorithm for LiDAR bathymetry of very shallow waters".
 
"Design and evaluation of a full-wave surface and bottom-detection algorithm for LiDAR bathymetry of very shallow waters".

Jury's rationale for the paper selection
This paper presents a new contribution to  multimedia lidar methodology for shallow water bathymetric mapping. The  authors’ SVB (surface, volume and bottom) algorithm represents a new,  innovative contribution to underwater topographic mapping. A considerable  advantage of their method is that it relies only on a single laser wavelength.  The Jurors were impressed with the detailed modelling of the return waveform,  the clarity of the explanation, the convincing experimental results and  potential for broader applicability of the method.
  On behalf of  the ISPRS and the U.V. Helava Award Jury, I would like to congratulate the  authors for this distinction and thank them for their contribution. I also hank  the sponsors of the Award and the Jury members for their thorough evaluations.
