Cover Image
This month’s cover image is provided
by NIIRS10, the Madison, Alabama based
company that has developed
GeoCue, a family of geospatial
workflow management tools. The
cover images are a series of views of
a large county-wide lidar project being
managed in GeoCue. The background
image portrays the lidar strips
outlined with their true ground footprint.
The upper left image (with
smaller inset) shows the project partitioned
into 975 lidar “working segments” of approximately 1.5 million
points each superimposed on a lidar“
Ortho” backdrop. The center inset demonstrates using the lidar ortho
for
coverage analysis by rendering void areas as transparent and viewing the
image superimposed on a red backdrop. Note that gaps between adjacent
flight strips are clearly visible. The lower inset shows the utility of visualizing
voids caused by water body mirror effect by superimposing the lidar ortho
over EarthSat’s NaturalVue LANDSAT data. These tools provide enterprise
(multi-user) management of large projects, significantly reducing the time
spent in analysis and production management. The March issue of PE&RS will
include an in-depth GeoCue product family article.

Capabilities for automated mapping of stream channel
characteristics are assessed using a spectral angle
mapping approach on 80 cm multispectral imagery.
The main ground deformations of Paris, France are
revealed by a least squares adjustment of radar interferometry
data coupled with a temporal filtering.
