AND REMOTE SENSING
This month’s cover, provided by BAE Systems, shows how geospatial data supports
national security AND the national pastime. The image shows the site of the Little League World Series
to be held in Williamsport, PA this August. Event security planners will make use of one-foot and six-inch
color orthophotos, generated by BAE Systems as part of the Pennsylvania PAMAP program. PAMAP consists
of orthophoto and lidar data covering the entire
Pennsylvania Commonwealth. One third of the state
is fl own and processed each year. The orthophotos
are color, one-foot pixel resolution and the lidar is
capable of supporting two-foot contours.
BAE Systems uses SOCET SET® photogrammetric
software to georeference, orthorectify, and mosaic
the aerial imagery data. These images of the Little
League World Series site are particularly exciting,
since this is the League’s 60th anniversary for holding
this event, and will be very useful in ensuring a safe
and secure competition. Play Ball!
The accuracy of digital elevation models derived from digitizing
contours on topographic maps and from autocorrelation
of stereo photographs is investigated throught comparison
with elevation data from a ground survey.
Object-based classification applied in vegetation mapping at
alliance level with 1-meter resolution airborne imagery compared
with conventional pixel-based classification.
A variogram-based texture analysis was tested for classifying
detailed urban land-use classes, such as mobile home, singlefamily
house, multi-family house, industrial, and commercial,
from a digital color infrared aerial photograph.
The development of automated classification methods for
vegetation and biotope type mapping from the new generation
of ultra high-resolution remote sensing data.
