corporate entities recognize these infrastructure needs.
In forming corporate partnerships and distribution
alliances, each of the companies is using different
strategies, providing many consumer alternatives for
value-addedimages (georegistration,orthorectification,
feature enhancement, radiometric intensification, etc.)
and value added products (DTM's, orthophotos, image
mosaics, fused MS and pan scenes, etc.). This total
service capability environment will strongly influence
the entire GIS/mapping community to coalesce many
of its traditionally fragmented, small (what is
colloquially known as Mom and Pop outfits) corporate
businesses into large corporate entities or limited
liability coalitions. This should not be considered a
negative sign, but rather a sign of technological,
industrial and scientific maturation. The market will
increase as consumers become more sophisticated and
less concerned with the technical complexities of
image processing, which has been a traditional
necessity.
Institutional Issues
International acceptance of the concept for high
resolution space imaging systems to commercially
deliver image data on a daily basis, which heretofore
has been the privileged domain of governmental
organizations, is a primary issue which will soon be
tested. As these commercial systems come on-line, it
can be expected that the need for an international
consortium may arise (Perhaps an INTEOSAT along
the lines of INTELSAT). Issues and needs of
common interest to the commercial operators include
open skies policies, coordination of orbit allocations,
pricing competition with government systems, data
copyright protection, ombudsmanship to address
sensitive political events, exclusivity, etc. It is quite
conceivable that the growth of these commercial
ventures will lead to significant commercialization of
many government mapping programs.
Benefits of Commercial Digital Imaging Systems
Even with the high capitalization costs of satellite
systems, their advantages of imaging timeliness, rapid
delivery, digital form, simultaneous pan and MS
coverage, superior coverage per processing unit, temporal
repetitivity, radiometric dynamic range and stereometric
fidelity make them very cost competitive with aerial
images. In fact, for square unit of coverage, aerial
images are projected to be more than twice as
expensive to acquire.
A Look into the Future
It is uncertain how many of these commercial ventures
will survive in the competitive marketplace. The
future is promising for many of them because of the
increasing reliance of modern technological tools and
social services for identification of locations and
attribution of people, places and things. Digital
technology is here to stay and digital imaging
technology is in the forefront of automated
information systems. Societal needs for information
from imagery will migrate from basic mapping
products to temporal, site specific updates. These data
and information revisions will be requested frequently
on an annual to hourly basis, in many ways the
requests will be analogous to today's weather updates.
Spatial resolutions available from satellites will
increase with international recognition of the benefits
of all-digital imaging and processing technology. The
aerial imaging industry will be transformed to digital
imaging and mostly integrated with the commercial
satellite companies. Many more constellations of
Earth observing satellites carrying varieties of
advanced sensors, from dial-a-band hyperspectral to
precise pointable dial-a-scale will be launched. On-
board storage and processing capabilities will permit
on-satellite image comparison (change detection) and
filtering so that only specified change data need be
transmitted to ground processing information systems.
As we in the spatial information sciences mature and
learn to integrate our technologies into the
information market of the future, the burden of
educating our consumers to our technology will
diminish and the imagery origin of our products may
well be transparent to the majority of our future
sophisticated users of information from imagery. The
future is very bright and promising for the
photogrammetry/remote sensing/GIS community.
