5. MAPPING CAPABILITY 
As stated above sections, the ALOS system design is optimized 
for satellite mapping. Unlike current high-resolution 
commercial satellites, the ALOS realizes: 
global coverage by wide swath (up to 70km) and 
high resolution (2.5m) optical sensors, a massive data 
storage (96G bytes) on-board and longer visibility 
from a ground receiving station using a Japanese data 
relay satellite in geostationary orbit, 
better quality and frequent stereo/triplet images, 
with the height accuracy of 5m, even in cloud-capped 
area by in-track optical sensors and/or SAR in con- 
junction with a highly stable attitude control system, 
GCP-free pixel position determination by highly ac- 
curate position and attitude determination with very 
low thermal distortion structure. 
The ALOS will provide *homogenous quality data for 1/25,000 
scale global maps" including elevation, vegetation, land use and 
land cover data. 
6. CONCLUSION 
We are convinced the specification and performance of PRISM, 
AVNIR-2, PALSAR and other subsystems are fully met 
mission requirements, e.g. mapping. The ALOS data will be 
utilized mainly by Japanese governmental ministries, agencies 
and institutes, e.g. Ministry of Land, Infrastructure and 
Transport, Ministry of Agriculture, Forestry and Fisheries, 
Ministry of the Environment, Geographical Survey Institute, 
Japan Coast Guard, and so forth. In addition, we hope many 
312 
foreign countries try to use ALOS data as the source for their 
public purpose.
