The China Center for Resources Satellite Data and Application (CCRSDA) announced on Thursday that it will launch six geographical survey satellites in five years.

The center will also establish a high-resolution land observation project and build a data center for the satellites.

Set up in 1991, the CCRSDA completed China's first application system for resources satellites in August 1999. CBERS-1, the first in a series of earth resources satellites, was launched two months later.

Data from the satellites has been used in agriculture, forestry, city planning, environmental protection and disaster monitoring.
