Lidar datasets of Merrill Field Airport
in Anchorage, Alaska. These
dense, highly accurate 3D models
are generated from data collected
by two Optech lidar solutions:
the ALTM Airborne Laser
Terrain Mapper, and the ILRIS-36D
laser scanner. Large-scale coverage
is obtained by ALTM, which
operates from a helicopter or airplane
at altitudes ranging from 80
m to 3,500 m. Datasets produced
by ALTM feature vertical accuracies
as high as 5 cm. Close-range coverage is obtained by the tripod-mounted
ILRIS-36D scanner, which features a dynamic scanning range of 3 m to
beyond 1 km. With modelling accuracies as high as 3 mm, ILRIS-36D captures
the fine details quickly, safely and accurately. The data collected by
these systems stands on its own, but can also be combined in post-processing
to produce incredibly high-resolution, dimensionally accurate 3D models.

1029 Sensitivity of Digital Landscapes to Artifact
Depressions in Remotely-Sensed DEMs
John B. Lindsay and Irena F. Creed
The effectiveness of inadequate representation of surfaces
by grids and random errors in elevations to
cause artifact depressions in digital elevation models
of a range of landscape types is quantified.
1037 Image Misregistration Error in Change
Measurements
Hongqing Wang and Erle C. Ellis
The effect of image misregistration on feature-based
change measurements.

Lei Ji and Albert J. Peters
AVHRR NDVI Response to Precipitation in the northern

time series models that account for time lag and
seasonality effects.
1063 Triangulation of Well-Defined Points as a
Constraint for Reliable Image Matching
Qing Zhu, Jie Zhao, Hui Lin, and Jianya
Gong
The reliability and accuracy of stereo image matching
are improved by making use of the triangulation of
well-defined points as a constraint.
