A novel cloud removal method by fusing features from SAR and neighboring optical remote sensing images. [PDF]

open access: yesPLoS ONE
Optical remote sensing images were prone to extensive cloud coverage, especially under mountainous conditions with frequent weather changes. To address this issue, this paper proposed a novel cloud removal method that integrated features from SAR and ...

REPRESENTATION AND RECONCONSTRUCTION OF TRIANGULAR IRREGULAR NETWORKS WITH VERTICAL WALLS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
Point clouds obtained by aerial laser scanning are a convenient input source for high resolution 2.5d elevation models, such as the Dutch AHN-2. More challenging is the fully automatic reconstruction of 3d city models.
