A graph-based model to locate rooftops and demolished buildings based on older
footprint maps is introduced.

A contextual global registration of partially overlapping point clouds in urban scenes is
presented. The approach extracts feature points, establishes correspondence candidates
using a contextual rule-based method which is pruned by a new penalization strategy.

Pavement marking visibility is automatically evaluated based on retroreflectivity using
mobile lidar sensors such as the Leica Pegasus. The paper introduces a calibration
approach to perform the task. Various configurations to quantitative assess the accuracy
of the proposed approach are discussed.

Authors propose a comprehensive total vertical uncertainty (TVU) model for topo-bathy-
metric lidar systems. The TVU model consists of a combination of analytical uncertainty
propagation for the subaerial portion and Monte Carlo simulation models for the
subaqueous portion. Tests on a topo-bathymetric lidar datasets show that the approach
captures the variability of uncertainty with depth while providing conservative estimates
of uncertainty.

An incremental updating method for land cover maps based on image cosegmentation
and a geo-eco zoning rule database is presented. Cosegmentation of images is first
used to extract changed pixels which is then improved by using the geo-eco zoning rule
database to detect and remove spurious changes.
