There are several types of space technology applications including
(i) remote sensing, (ii) satellite navigation
systems such as the
Global Positioning System (GPS), and (iii) satellite communication
systems. In this report, the main emphasis
is on projects that rely
on the results of remote sensing applications.
Remote sensing is a technique to observe the earth’s surface or
the atmosphere with cameras or sensors installed in satellites. Its
advantages include
(i) the ability to record data for
inaccessible or dangerous
areas;
(ii) a comparatively low cost per unit of area;
(iii) wide, objective,
frequent, and periodic data collection; and
(iv) the availability of historical data.
These advantages enable remote monitoring of project sites
and cost-effective long-term periodic
monitoring of the wide
area necessary for development activities such as environmental
monitoring and climate change impact assessment. Remote
sensing is particularly effective in developing member countries
(DMCs) that suffer from the lack
of infrastructure for data
acquisition. Table 1 shows typical applications in each sector in ADB.
