3-Dimensional pre- and post-fire comparison of forest areas

Akça, Mehmet Devrim; Stylianidis, Efstratios; Poli, Daniela; Gruen, Armin; Altan, Orhan; Hofer, Martin; Smagas, Konstantinos; Martin, Victor Sanchez; Garcia, Alejandro; Jimeno, Elisa; Walli, Andreas (International Society for Photogrammetry and Remote Sensing, 2018-03-06)

Forest agencies give special attention to forest fires where post-disaster loss can rarely be gauged in a quick and economic way unless an appropriate technology is adopted. Determination of the planimetric and volumetric ...
A precision estimation method for volumetric changes

Akça, Mehmet Devrim; Stylianidis, Efstratios; Gruen, Armin; Altan, Orhan; Hofer, Martin; Smagas, Konstantinos; Sanchez Martin, Victor; Walli, Andreas; Jimeno, Elisa; Garcia, Alejandro (IEEE, 2019-06)

Earth surface changes are often computed by comparing the sequences of digital elevation models (DEMs) so called the DEM of difference (DoD) method. We present an operational DEM generation, co-registration and DoD comparison ...
Quality assessment of 3D building data

Akça, Mehmet Devrim; Freeman, Mark; Sargent, Isabel; Gruen, Armin (Wiley-Blackwell Publishing, 2010-12)

Three-dimensional building models are often now produced from lidar and photogrammetric data. The quality control of these models is a relevant issue both from the scientific and practical points of view. This work presents ...
