Image Search and Acquisition Services |
|
Archer Geographic is a leading edge
imagery provider focused on value added services, as
distinct from a satellite or airborne system operator or
raw data provider. We work with every commercial and
public source of satellite and aerial imagery to provide
client-driven imagery solutions. Other value added
imagery providers typically align with one satellite
operator, and therefore end up pushing one data source
whether or not it is the best source for a project or
client. Archer Geographic works for our clients only,
not a data provider, with the needs of a particular
project determining which imagery data source to
utilize.
Archer Geographic offers a comprehensive image search and
acquisition capability. We can search millions of image records to search for a
particular site or location across the entire array of
satellite and aerial image data providers in both the
public and commercial sectors to find the optimal
imagery for a project, based entirely on the needs and
budget of the project. If suitable imagery for a project
does not exist, we can task a satellite or contract with
one of our aerial data providers to acquire the
necessary imagery.
For attorneys and other legal
professionals, our Satellite Image Evidence (SIE) Group
offers specific image evidence
searches. For clients
with an ongoing need to image a site or location, Archer
Geographic offers site monitoring
services.

SATELLITE IMAGERY
SOURCES

The following is a list of the
primary imaging satellites, all of which Archer
Geographic works with. As of 2008, there will be a constellation of
nine super high resolution satellites in global
operation with a spatial resolution of one meter or
less. Additionally, there will be several others with
around a two meter resolution, and two high resolution
radar satellites offering all-weather capability. Medium
resolution satellites are also useful in regional scale
mapping and applications.

Archer Geographic also utilizes current and
historical aerial photography to compliment satellite
imagery in many projects. Sources of historical and current
aerial photography for a site depend upon its region,
state, and specific location, but generally include
numerous private companies as well as a host of
government sources. Federal sources of aerial imagery
include the National Aerial Photography Program (NAPP)
and its predecessor program the National High Altitude
Photography Program (NHAP), the U.S. Geological Survey,
NASA, and declassified satellite photos. State, county,
and municipal governments are also often excellent
sources of aerial photography.
The needs of a specific project will determine the type of
satellite and aerial imagery most suitable for a
particular application. Archer Geographic specialists
regularly work with all image types, with color imagery being the most
prevalent, but also black and white (or panchromatic),
color infrared, multispectral, hyperspectral, radar, and
low resolution meterological imagery being utilized for
many applications.
