lmagery is used to map various 
geographic features such as land- 
use, crop patterns, types of soil 
and classification of salinity areas. 
The imagery is recorded with the 
help of SPOT satellites, launched 
and owned by France. 
IIMI also conducts field sur- 
vey. Field data is collected to 
interpret and validate the satel- 
lite data and both are stored and 
matched using Geographical In- 
formation Systems. Results re- 
ceived from mutual contribution 
through statistical approach to- 
wards collected data from vari- 
ous disciplines serve as a bench- 
mark to obtain the above- 
mentioned features in respect to 
all the areas. 
Conclusion 
Pakistan lags far behind in re- 
mote sensing technology. The 
quantity of work, done so far at 
government level, is negligible. It 
will be prudent if work is acceler- 
ated in this field without further 
delay. Pakistan should launch its 
own Earth Imaging Satellite and 
introduce remote sensing technol- 
ogy in WAPDA, Soil Survey of 
Pakistan, Survey of Pakistan and 
Irrigation Departments, etc.. Now 
is the time to discard obsolete and 
outdated methods and endeavour 
to adopt new techniques in agri- 
culture. 
Ultimately to have thriving 
crops, to become self sufficient in 
grain production and agricultural : 
development of the country. 
There is no alternative except to 
have the water management to use 
modern techniques without any 
more loss of time. The motto 
should be "That not a single drop 
of water be wasted and not a sin- 
gle inch of land be left unwa- 
tered".
