the world are researched and the ones that Turkey has to apply 
are determined, considering the criteria below (Batuk, 2004): 
e The definition of the data, the coordinate system, 
datum/ellipsoid information, digitizing type, 
accuracy/scale, data quality, exchange format, 
documentation standards 
» The definition of the product, symbology, accuracy 
and quality, documentation standards 
e The definition of the process and documentation 
standards. 
e Geometry, topology and raster data storing structure, 
query language, interoperability, web portal, software 
standards and etc. 
e Hardware standards 
3.2.2 Organizational Structure of the System 
This system is designed, containing the relationships about data 
and information access, disaster management communication, 
risk reducing and preparation, post-disaster problems between 
prime ministry, governorship and other institutions. The service 
and duty of the institutions are taken into consideration and 
adapted to the system, without making crucial modifications in 
their existent organizational structures. On the other hand, a 
particular care is taken to create a structure that will not be 
influenced by the public management reform that is being 
discussed in TBMM.

3.2.3 Data Design 
Disaster and emergency management is vertical application 
from the view of GIS, that is to say, it is connected to the 
several institution and data. It is determined that there are 3 data 
groups as base for disaster and emergency management (OAS, 
1990). These are as follows: 
eo Natural hazards information, which denotes the 
presence and effect of natural phenomena. This 
information should ideally include the location, 
severity, frequency, and probability of occurrence of 
286 
a hazardous event. Location is the easiest for planners 
to find; the rest can often be obtained from scctoral 
agencies, natural hazard research and monitoring 
centers, and, increasingly, integrated development 
planning studies. 
* Information on natural ecosystems (e.g., slopes and 
slope stability, river flow capacity, vegetation cover), 
which provides the basis for estimating the effect 
natural hazards can have on the goods and services 
these systems offer and also determines the factors or 
conditions that create, modify, accelerate, and/or 
retard the occurrence of a natural event. 
e Information on population and infrastructure, which is 
the basis for quantifying the impact natural events, 
can have on existing and planned development 
activities. Large scale data describing lifeline 
infrastructure and human settlements, for example, 
are critical elements for preparing vulnerability 
assessments and for initiating disaster preparedness 
and response activities. 
e And other inventory data. 
Depending on this basic information the data that has to be used 
while designing AFAYBIS is grouped at below and classes are 
created according to that. The classes in these data groups are 
designed using object oriented methodology. The class 
diagrams are created in UML 
e Base Data: Buildings, administrative boundaries, 
hydrography, elevation information, referance points, 
city development plans, land usage, soil and geology 
maps, Existing ortophotos and large scale maps, 
cadastral information etc. 
e Transportation Data: Land-sea and airways etc. 
e Infrastructure Data: Gas, electricity, water, sewer 
system and telecommunication etc. 
e Data about Critical Areas: Important or hazardous 
areas (Fuel-oil stations etc.), historical places, high 
populated settling and business centers, health, 
education, security etc. 
e Data for disaster- emergency conditions: Temporary 
residences to be built after the disaster; disaster 
management centers and the staff in charge etc. 
e Institutions and inventory data: Equipment inventory 
to be used during the disaster (working machines, 
transportation vehicles etc.), medical equipments, 
food and water stocks, inventory for the staff in duty 
(medical, security). 
e Data for the Risky Arcas: Risky arcas that are 
planned according to various scripts (erosion, 
landslide, soft ground etc.) 
3.2.4 Work Flow and Process Design 
This part is considered as the chain of duties before, during and 
after the disaster that will reduce the risk taken. On the other 
hand, to manage the work flow and process design on the 
electronic media, the question of which institution will be 
renewing which data is answered. (Table 3.1 and Table 3.2)
