GeoEye-1

GeoEye-1 launched on September 6, 2008

Next-generation satellite with the highest resolution and most advanced collection

capabilities of any commercial imaging satellite

GeoEye-1 offers unprecedented spatial resolution by simultaneously acquiring 0.41-

meter panchromatic and 1.64-meter multispectral imagery

Imagery from the panchromatic and multispectral sensors can be merged to create0.5 meter color imagery (pan-sharpened) products

It can collect 700,000 square kilometers (sqkm) of panchromatic imagery (350,000

square kilometers in multi-spectral) in a single day, downlink imagery in real-time to

ground stations, and can store 1.0 terabits of data on its solid-state recorders



9/33

IKONOS

Worlds first commercial satellite to collect black-and-white (panchromatic) images

with 0.82-meter resolution and multispectral imagery with 3.28-meter resolution

Imagery from the panchromatic and multispectral sensors can be merged to create

0.82-meter color imagery (pan-sharpened)

IKONOS has collected more than 320 million square kilometers of imagery over

every continent From a 423-mile high orbit, IKONOS has a revisit time of once every three days and

downlinks directly to more than a dozen ground stations around the globe

Capacity

IKONOS and GeoEye-1 both are built to paint a target

area

Based on the average scene size each can collect

(4,000 sqkm for IKONOS and 5,100 sqkm for GeoEye-1), total capacity is quite large

Combined capability up to 650,000 square kilometers

per day in multispectral mode and even more area in

panchromatic only

GeoEye-1 Bi-Directional Scanning



14/33

Quality and Access

Two key points to satisfy the SDMI requirements (to be defined)

Image quality is essentially dependent on three factors: sensor

performance, ground processing, and quality assurance

ISO 9001:2000 certification provides a foundation to control and measure

performance against these factors GeoEye-1 delivers NIIRS 5.7 imagery and IKONOS delivers NIIRS 4.5

imagery

This constellation affords the SDMI access to a high capacity constellation

with global access to virtually any location on the Earth

Operating in a polar, sun-synchronous orbit, each satellite will orbit the earth

approximately 15 times per day with 3-4 passes per day over Alaska

Product Offerings

GeoEye recommends our GeoProfessional product at 10-meter CE90

Ortho-rectified using proprietary processes perfected in our production facilities and optimized for

the data collected by both sensors

Available in two levels of accuracy allowing delivery of the most suitable and precise terrain

corrected color products

Precision level product is available in a key areas at 4-meters CE90, but requires more accurate

terrain models and ground control

Perfect product for projects requiring high-resolution and medium-scale accuracy when ground

control can be costly and/or very difficult to acquire, such as in many parts of Alaska

Available in multiple band combinations: panchromatic, 4-band multi-spectral (red, green, blue

and near-infrared), and pan-sharpened(color)

GeoProfessional meets an accuracy specification of 15-meters CE90 at 1 meter and 10-meters

CE90 at 0.5 meter. Available in both 8-bit and 11-bit

Both sensors have the unique capability to do same pass stereo collection, which allows for bothimages in the pair to be collected at the same time maintaining consistent environmental

conditions in both images

Stereo products are so accurate that they suitable for use as control for other sensor data in

remote Alaska areas

18/33

Horizontal Accuracy

Native Horizontal Accuracy: GeoEye-1 image accuracy is 5-meterCE90 (5.7-meter CE95). IKONOS image accuracy is specified at 15-meter

CE90 (17-meter CE95), but operational tests show actual performance is 7-

meter CE 90 (8-meter CE95). RPC data is provided with Geo and Stereo

products at no extra cost

Improved Horizontal Accuracy: GeoEye image accuracy can approach

the accuracy of the applied ground control, limited only by pixel resolution.

With suitable GCP, IKONOS image accuracy is 2-meter CE95 and GeoEye-

1 is 1-meter CE95. These image accuracies are at nadir, and thus, exclude

terrain displacement due to DEM errors



19/33

Horizontal Control Distribution

As control is only necessary for the 4-meter CE90 product, GeoEye does

not anticipate the need for ground control points to meet Alaska SDMI

objectives

However, for the Precision products, we space ground control

approximately every 50 km down the length of each image strip

Control points located in the strip overlap areas reduce costs. GeoEye can

obtain ground control points (GCP) or accept them as Customer Furnished

Information(CFI)

We do not, however, anticipate needing GCP for the GeoProfessional ortho-

image products we propose to deliver for the current requirements



20/33

DEM Requirement

To achieve the SDMI specification of

1:24,000 NMAS (12.2 meters CE90),

GeoEye would require a DEM of 19-

meters LE90 or better



21/33

Ortho-Mosaic Production

GeoEye leverages a strong network of partners all over the globe

Specifically in the state of Alaska, there are partners on which we

would rely to assist with the ortho-image production

These partners have not only production knowledge and many years

of experience with IKONOS data and now GE-1 data, they have adeep knowledge and understanding of SDMI needs

GeoEye can also provide ortho-mosaic imagery directly to the SDMI

The production time, regardless of who processes, would depend on

the size of the ortho-image and on the necessity to re-collect for

cloud cover patching

23/33

Swath Width

Nadir swath width for IKONOS is 11.3 km, and 15.2 km for GeoEye-1

Collect large areas, such as Alaska, in one-degree (112km) long strips

IKONOS and GeoEye-1 can each collect three to four strips per pass

Adjacent strips are collected to facilitate tonal balance during ortho-mosaic

generation GeoEye-1 averages 2,500 sqkm per minute for large area collects

A 1,000 km long pass takes 2.45 minutes, so just over 6,000 sqkm are

collected on said pass

With three to four passes per day over Alaska, GeoEye-1 will collect over

20,000 sqkm per day

IKONOS averages 1,900 sqkm per minute; 4,655 sqkm per 1,000 km pass;

or16,300 sqkm per day.



24/33

Rapid Delivery and Ground Receiving

Station Options

Network of ground stations strategically located around the world to

command and control our spacecraft

Responsive direct downlink and rapid imagery processing and

dissemination

Ground station placement is optimized to afford maximum opportunities to

downlink, process, and deliver imagery to our customers to meet stringent

timelines

GeoEye-1s electronic image delivery worst case scenario is 2 hours 20

minutes from collection to delivery

Our Antarctic ground station uniquely enables GeoEye to provide this timely

and flexible downlink service. With access to this Antarctic ground station,we are able to download and start processing imagery instead of waiting for

the sensor to complete a full orbit of the Earth before downloading

Ground stations in Barrow and Fairbanks, Alaska, that will be leveraged for

the SDMI



25/33

Production Volume

GeoEye can collect 5.4 million sqkm in the 150-day season by combining

16,300 sqkm per day from IKONOS with 20,000 sqkm per day from

GeoEye-1 (Alaska)

Clouds are, however, significant during the collection season in Alaska

After accounting for clouds, feasibility analysis shows it will take 791 in-

season days to collect mainland Alaska

Some of the outlying islands may take two years to collect because of poor

weather conditions



26/33

Delivered Products

We complete delivery of raw imagery and/or ortho-products by several modes ranging from

physical electronic media (DVD, Firewire, etc.) to File Transfer protocol (FTP), as well as through

dedicated, high-bandwidth communication links

We provide a direct uplink and downlink capability to customers with the necessary receiving and

processing capabilities.

We deliver our data ready for ingestion and use by standard commercial exploitation software,

Geographic Information Systems, and specialized systems Multiple formats including industry standard GeoTIFF, as well as National Imagery Transfer

Format (NITF) Versions 2.0 and 2.1.

Shipped with a text metadata file, license file, shape files, JPEG overview image and JPEG world

file

Shapefiles show area of interest (AOI), delivery component layout, and source image footprints

with acquisition geometry

The metadata text file includes GeoEye contact information, order parameters (area of interest,spectral bands, and coordinate system), source image description (acquisition date, sun angles

and viewing geometry), and product file descriptions (file names, sizes, and coverage)



27/33

Licensing and Pricing

As the requirements for the SDMI have not been fully realized, GeoEye will be very

flexible with pricing and licensing to best suit SDMI budget and product needs

Very open to considering other license types, such as a Non-commercial

Unrestricted license that allows unlimited distribution (uplift factor to consider in this

scenario)

Once requirements are determined, GeoEye will work very closely with the SDMImembers to address licensing needs that are mutually satisfactory

Alaska has already purchased a fair amount of monoscopic and stereo IKONOS data

that could be re-licensed for an uplift fee in such a way to allow for use across the

state and data could be re-processed to meet the specifications of the SDMI

The National Geospatial-Intelligence Agency (NGA) has identified the state of Alaska

as a priority for collection on the new GeoEye-1 satellite

GeoEye is open to discussing with Alaska and the NGA how we may leverage this

collection to meet the SDMI needs. Options include ensuring the states collection

priorities are met, and/or licensing the NGA-collected data via uplift for SDMI use



28/33

Licensing and Pricing Contd

We consider project size and other factors that allow us to provide the best

possible value for the SDMI

We will work through our strong allegiance of partners and/or directly with

SDMI to deliver the best products, licensing, and pricing

If the SDMI finds exploring pricing for the entire state an overwhelming

prospect, we wish to emphasize that we can work with SDMI and our

partners to identify priority areas to collect and process

GeoEye will support developing a license and pricing model that works for

all parties
