Downtown Perth and Freemantle
Downtown Perth, seen by the SPOT satellite with the Swan
River. In fact the river forms in this section a swan with the
Heirisson Island at its breast. Two data set from 1986 and from
2004 have been combined. In a span of only 18 years the dynamic
development of Perth is clearly visible also from space. In the
image new buildings, reconstructions or enlargements of smaller
houses are presented in red, while light blue and white shows
constructions or places older than 18years.
Freemantle 1986 and 2004 seen from space. is found
here. Two images from
SPOT satellite combined into one show in red new buildings or
enhanced reconstructions. Very clear are the enlarged port
facilities. These changes have also changed the ocean current:
red shows accumulation and light blue erosion along the beach.
In the city many reconstructions can be discovered such as new
large construction in the image centre or entire quarters as
visible in the lower right corner.
Technical information
