Early Images Series
The images listed along with selected enlargements below are
available for viewing. Note that the images have been
deliberately sub-sampled so that they are small enough for
display on the web. Consequently, the amount of detail visible
is drastically reduced from the original data sets. We
recommend you use a display monitor with a resolution of at
least 600 x 800 pixels with 256 colors to appreciate the
remaining detail.
Perth, Australia
This RADARSAT image of the west coast of Australia extends
approximately 100 kilometres south of Perth, capital Western Australia. The image clearly shows the two dominant
landforms in this area, the coastal plains and the uplands of
the Darling Range along the right side of the image.
The bright areas along the coast at the top of the image are
from the city of Freemantle just south of Perth. A series of
round lakes can be seen to the east and south of Freemantle.
The two southernmost lakes are Thompson Lake (closest to the
coast) and Lake Forrestdale. The causeway to Garden Island
from Freemantle is clearly visible as are several jetties in
the bay north of Freemantle. South of Freemantle, the cities of
Rockingham and Mandurah can also be seen along the coast. The
lower half of the image shows a coastline which is largely
uninhabited, with low-lying coastal vegetation (grey tones)
interspersed with areas of open water (dark tones).

St. Lawrence River, Quebec, Canada
This portion of a ScanSAR image shows where
the Gulf of St. Lawrence at
the Gaspé Peninsula. It covers an area of about 140 by 159 km. The original ScanSAR scene was 300 km
square.
The image shows the landforms on either
side of the St. Lawrence.
Thicker river ice is compressed along the north shore of the
Gaspé Peninsula. In the water to the north, strips and
patches of newly formed ice can be seen.

Maui, Hawaii
This first RADARSAT image of the Hawaiian Islands was acquired by the
Canadian Space Agency to support the opening activities of the
Pacific Disaster Center on Maui, Hawaii, February 21 to 23, 1996.
This image was acquired on 10 February 1996, 06:08 hours,
local
Hawaii time, received by the Canadian Centre for Remote
Sensing, and processed by RADARSAT International.
The Pacific Disaster Center (PDC) is a cooperative United
States federal and State initiative, with a mandate to bring
new resources to emergency management, which could be
supported by RADARSAT's international partners: the National
Oceanic and Atmospheric Administration (NOAA) and the National
Aeronautics Space Administration (NASA), and/or RADARSAT
International (now MDA Geospatial Services).
The Maui image features the Haleakala Volcano near the center
of island along with evidence of previous lava flows toward
the ocean.
Two features can be seen to the south (beneath) of the
island may be coral reefs, but this is
unconfirmed.
On a subsequent pass, RADARSAT collected additional data in
Fine Beam 5. Shown here is an enlargement of the Kahului
Airport, in the northwest portion of the island.

Osaka, Japan
This Standard beam mode (S3) image was acquired using one of
RADARSAT'S two on-board tape recorders in the vicinity of
Osaka and Kobe, Japan. The water body (nearly black) is Osaka
Bay with Kobe visible along the top shore and Osaka to the
right. The two reclaimed islands visible near Kobe were
severely damaged during the January 17, 1995 earthquake. There
is a distinct contrast between the urban areas and the steeper
mountainous terrain which appears as darker tones along the
north (upper) shore of Osaka Bay. There are many ships in Osaka Bay.

Oregon, United States
During Flooding
The first image (left) near Portland Oregon was
taken February 13, just following the peak of the flood. It shows
portions of the Columbia River and the nearby flooded areas.
Post Flooding
The second image (right ) was taken on February
14, of areas which appear to have been damaged by the flood
waters.
