rather lt has been that in the application of 
geographical data obtained from other media have 
been found rather dissatisfying. However, if the 
digital maps of the area to be studied are available, 
it should be preferred to use these maps instead of 
redigitizing to obtain data, in order to save time, 
money and personnel. 
e To spend out the GIS to countrywide is highly 
necessary and inevitable. This should be achieved 
with the contribution of all concerned individuals and 
institution. 
e The difference between mapping systems and GIS 
should be clearly established. Institutions and bodies 
forming GIS ,have to be very careful to select the 
software which is most functional and independent 
from the hardware employed. 
e Continuing efforts should be made to faster 
cooperating between government, industry and 
universities. The red tape(bureaucracy) experienced 
in the data exchange among the sectors must be 
avoided as much as possible . 
€ More support needs to be provided for research at 
the universities. Sources of funds must be created 
for technology transfer. 
The last decade has seen a growing awareness and 
concern regarding the effect of the local and global 
environment on human health and nature. In the face of 
this concern ,there is an increasing need for accurate 
and reliable information to underpin epidemiological 
research. GIS offer powerful instruments for the 
construction of environment model , but to be widely 
useful they must make maximum use of the limited and 
disparate data available on both environmental 
conditions and health come. In Turkey, these data are 
not available in every region therefore, we have to 
establish stations which collects these data in certain 
time intervals .
